A <strong>Cost</strong>-<strong>Benefit</strong> <strong>Analysis</strong> <strong>of</strong> <strong>Rural</strong> <strong>Secondary</strong> <strong>School</strong> <strong>Consolidation</strong><br />
Executive Summary<br />
1. This cost-benefit analysis <strong>of</strong> rural secondary school consolidation<br />
aims to take into account all the major relevant social and economic<br />
impacts <strong>of</strong> the policy in accordance with H M Treasury guidelines. As<br />
Treasury documentation makes clear in the context <strong>of</strong> central<br />
government, an education authority focus exclusively on financial<br />
outlays is not required by the pursuit <strong>of</strong> efficiency and effectiveness<br />
on behalf <strong>of</strong> the taxpayer when the authority has other policies and<br />
obligations to take into consideration as well.<br />
2. A hypothetical example is studied in which a rural secondary school<br />
<strong>of</strong> 350 pupils is closed and the students distributed to two others,<br />
one a school initially also <strong>of</strong> 350 and one initially <strong>of</strong> 500. This<br />
reconfiguration can be expected to reduce authority financial costs<br />
per pupil and ‘empty places’. But it does so by imposing other costs<br />
on the authority through its obligations to provide more transport<br />
for the students who must now travel greater distances.<br />
3. In addition greater costs are imposed upon the pupils, who must<br />
spend more time travelling. Standard UK transport project appraisal<br />
procedures value such extra time saved or spent and therefore<br />
consistency in the allocation <strong>of</strong> public funds requires that school<br />
consolidation policies should do so as well.<br />
4. A third cost imposed by the hypothetical school closure is a loss <strong>of</strong><br />
local income and employment- with the attendant social disruption.<br />
While the relocation may be expected to benefit income and<br />
employment in other local communities, the authority may not<br />
consider this redistribution as consistent with their social policies.<br />
5. On the benefit side <strong>of</strong> the policy balance there may be educational<br />
pay<strong>of</strong>fs for students in larger schools <strong>of</strong> the size considered here. An<br />
attempt is made to estimate their monetary value – that is how<br />
much extra must be spent to obtain equivalent educational<br />
performance in the school configuration before the hypothetical<br />
consolidation, compared with how much after. Even more<br />
4
uncertainty is attached to the disposal value <strong>of</strong> the hypothetical<br />
school site. Therefore a sensitivity analysis is conducted to see what<br />
values are sufficient to tip the net benefit balance between positive<br />
and negative.<br />
6. The conclusion <strong>of</strong> the study is that comparing the above costs and<br />
benefits, calculated on as plausible and as robust assumptions as<br />
possible, yields a negative balance from the hypothetical school<br />
closure. What this means is that the authority would not be obliged<br />
on grounds <strong>of</strong> efficiency and effectiveness to close the rural school.<br />
However, if for example, the authority decided that it was<br />
appropriate to shift the full costs <strong>of</strong> educational provision more on<br />
to students and away from the taxpayer, it might chose to do so, at<br />
least if other policies affecting the remaining components <strong>of</strong> the<br />
cost-benefit analysis also pointed to such a decision.<br />

A <strong>Cost</strong>-<strong>Benefit</strong> <strong>Analysis</strong> <strong>of</strong> <strong>Rural</strong> <strong>Secondary</strong> <strong>School</strong> <strong>Consolidation</strong><br />
1. Introduction<br />
This report is an appraisal, broadly following the guidelines laid down in HM<br />
Treasury's Green Book, <strong>of</strong> secondary school closure policy. The Welsh Assembly<br />
Government is signed up to following this Treasury guidance on project and<br />
programme appraisal and evaluation. Although the guidance refers to ‘central<br />
government’, local authorities are mainly funded from the centre, and therefore<br />
the use <strong>of</strong> the same principles for ensuring effectiveness, efficiency and economy<br />
in public spending makes sense.<br />
The Treasury states that the Green Book principles are relevant<br />
‘to any analysis used to support a government decision to adopt a new policy, or<br />
to initiate, renew, expand or re-orientate programmes or projects, which would<br />
result in measurable benefits and/ or costs to the public.’ (S1.8)<br />
The guidance recommends procedures for cost-benefit analysis – in particular for<br />
valuations <strong>of</strong> outcomes. This involves taking into consideration wider social<br />
impacts as well as immediate financial outlays and savings.<br />
‘Wider social and environmental costs and benefits for which there is no market<br />
price also need to be brought into any assessment. They will <strong>of</strong>ten be more<br />
difficult to assess but are <strong>of</strong>ten important and should not be ignored simply<br />
because they cannot easily be costed’. (s5.12)<br />
Such social costs and benefits might include quality <strong>of</strong> educational provision, as<br />
well as the educational experience <strong>of</strong> the pupil in the wider sense such as travel<br />
time, length <strong>of</strong> day, and safety.<br />
The present report considers the following cost and benefits <strong>of</strong> rural secondary<br />
school consolidation;<br />

2. Measurement Issues<br />
To weigh costs against benefits <strong>of</strong> secondary school consolidation both must be<br />
in comparable time units and preferable valued in monetary terms.<br />
Conventionally magnitudes are capitalised into present values but the present<br />
study instead considers annual flows <strong>of</strong> benefits and costs. It does so because<br />
education provision is a permanent obligation (there is no project end point) and<br />
because projecting costs and benefits into the future creates additional<br />
uncertainties and margins <strong>of</strong> error, which it is judged desirable to do without. So<br />
implicitly this exercise assumes that conditions this year will continue into the<br />
future.<br />
While financial outlays are readily available, other costs and benefits are less<br />
easily measured in monetary terms, which may explain, but not justify, why<br />
they are <strong>of</strong>ten ignored in assessing the merits <strong>of</strong> a policy. In the case <strong>of</strong> travel<br />
time, (English) Department <strong>of</strong> Transport estimates are widely used. But the<br />
value <strong>of</strong> a local community or <strong>of</strong> the quality <strong>of</strong> educational provision is more<br />
problematic. On occasion, as will be shown below, an analysis allows these<br />
intangibles to be treated as residuals so that values at which the policy decision<br />
would be altered can be calculated, and compared with policy makers’<br />
judgements.<br />
3. <strong>Cost</strong> per Pupil and <strong>School</strong> Size<br />
The apparent financial advantages <strong>of</strong> school consolidation are illustrated by<br />
figure 1. Each cross represents a particular school. The figure shows the fall in<br />
costs per pupil with secondary school size in Wales in 2010. There is a<br />
substantial scatter around the line <strong>of</strong> best fit because other school characteristics<br />
may influence costs, as well as size. But the relationship is helpful because<br />
secondary schools in Gwynedd are close to this Welsh average line.<br />
Suppose a school <strong>of</strong> 350 pupils was closed, and 150 <strong>of</strong> those students went to<br />
another school <strong>of</strong> similar size, raising numbers to 500. The remaining 200<br />
students travel to a school that originally educated 500, but is now expanded to<br />
700. The figure shows that around £200 a student is saved by putting the 150 in<br />
7
the school <strong>of</strong> now 500 students. But also the costs <strong>of</strong> educating those 350<br />
original students in the now expanded school are cut by around £200 a student.<br />
This element <strong>of</strong> the consolidation then saves £100,000. The gains from the<br />
consolidation with the larger school are greater. On the 200 students moved<br />
there around £500 a head is saved. The costs <strong>of</strong> educating the 500 students<br />
already attending larger schools also fall by perhaps £300. The ostensible<br />
financial total saved by this rationalisation amounts to about £350,000 or £1000<br />
per pupil.<br />
Figure 1 Budget cost per pupil in relation to school size, Wales 2009-10<br />
In Appendix A are average cost functions estimated for Gwynedd secondary<br />
schools between 2002 and 2010. The calculation with the parameters <strong>of</strong> the<br />
preferred equation yields about the same conclusion as above; that the<br />
immediate financial savings from the hypothetical consolidation would be about<br />
£1000 per affected student. Taking into account proportions <strong>of</strong> pupils entitled to<br />
free school meals, numbers in sixth forms and percentages not achieving any<br />
qualifications, does not significantly affect the results.<br />
8
4. ‘Empty Places’ and <strong>Cost</strong> per Student<br />
Education authority cost per pupil cannot be the sole index <strong>of</strong> efficiency or school<br />
performance. A school delivering a better education may be more expensive<br />
than another, but it is not necessarily less efficient; it may be worthwhile<br />
incurring higher costs for a ‘better’ school. Conversely it is not necessarily fair<br />
simply if all state schools incur the same costs per pupil. A pupil may receive<br />
different standards <strong>of</strong> education depending on the state school attended.<br />
Similar considerations apply to the idea <strong>of</strong> ‘empty (school) places’. This is a short<br />
run (with given school buildings and staff) equivalent <strong>of</strong> the cost per pupil<br />
indicator. If a school can take more students with the same resources, the<br />
financial cost per student falls – which in itself is clearly desirable. But as an<br />
over-riding goal <strong>of</strong> education policy it can be misleading. If students do not want<br />
to attend a particular school for good reason, such as the quality <strong>of</strong> education or<br />
the distance required to travel, it is likely to be an error to focus solely on filling<br />
the empty places – rather than for instance improving school quality.<br />
Demographic change may give rise to ‘empty places’ at particular schools but it<br />
does not necessarily follow that such schools must be closed or that students<br />
should be bussed in from elsewhere. The purpose <strong>of</strong> policy appraisal is to judge<br />
whether it is. Ultimately the elected authority must make decisions about the<br />
distribution <strong>of</strong> all the benefits and costs <strong>of</strong> school consolidation or maintaining<br />
the status quo with the best available information about their magnitudes.<br />
A school consolidation policy may be expected to increase travel time costs<br />
imposed upon students in exchange for a lower financial burden for the<br />
taxpayer. Even when the financial savings exceed the time costs, the authority is<br />
not obliged to conclude the policy, on these grounds, is desirable. It is only<br />
appropriate to do so if the outcome is consistent with their other objectives and<br />
policies<br />
5. Increased Student Travel Time<br />
What are the wider social and economic costs and benefits? Some are easier to<br />
quantify than others. These include greater pupil travel costs. When the<br />
(English) Department <strong>of</strong> Transport appraises priorities for road improvements<br />
9
the principal benefits that they weigh against the outlays are travel time and<br />
costs and safety. They have developed procedures for measuring these in<br />
various circumstances (Department <strong>of</strong> Transport 2009).<br />
‘The majority <strong>of</strong> journeys ... take place .... in the traveller’s own time. However,<br />
people implicitly put a value on their own time, in that they will trade a cheaper,<br />
slower journey against a faster, more expensive one.’ (1.2.11)<br />
In their guidance the Department <strong>of</strong> Transport note their valuations in their<br />
Table 2 includes those <strong>of</strong> retired people.<br />
It might be questioned whether non-earning school students should be treated<br />
as equivalent to retired persons. The democratic principles under-pinning <strong>Cost</strong>-<br />
<strong>Benefit</strong> <strong>Analysis</strong> imply that for present purposes there is no reason to treat<br />
young people and children differently from adults, economically active or retired.<br />
As the Transport department explain;<br />
If values <strong>of</strong> time for appraisal are based on an individual’s willingness to pay<br />
which are related to income, then strategies and plans will be biased towards<br />
those measures which most benefit travellers with higher incomes ...Investment<br />
will then be concentrated into high-income areas, and the interests <strong>of</strong> those on<br />
lower incomes, who may already suffer from relatively lower mobility and<br />
accessibility, will be given less weight. For this reason, multimodal transport<br />
appraisal should normally adopt the values for non-working time which is<br />
common across all modes and journey purposes.’(s1.2.14)<br />
In short, the journey to and from school should not be appraised any differently<br />
from other non-work trips.<br />
The 2002 value recommended by the English Department for Transport for noncommuting<br />
leisure travel time is £4.46 per hour. Uprating the leisure travel time<br />
to 2011values takes the figure over £5 an hour. Students travel for about 5<br />
days a week for 40 weeks a year – say 188 days. To how much extra travelling<br />
time are students committed with a school re-organisation? In relatively sparsely<br />
populated rural areas the position can be markedly different from in cities. There<br />
is some evidence that an extra 20 minutes each way (Appendix B) could be<br />
imposed on the average former pupil <strong>of</strong> a closed hypothetical school. If this were<br />
so, then conventional cost-benefit analysis registers a cost in the hypothetical<br />
10
example <strong>of</strong> the 350 students considered earlier, <strong>of</strong>;<br />
350x(40/60)x5x188˜£220,000 each year.<br />
6. Additional Vehicle Operating <strong>Cost</strong>s<br />
In addition to these extra time costs, there are those associated with the<br />
vehicles operation. Estimating these costs requires knowledge <strong>of</strong> how many<br />
students travel by bus, by car, by bicycle or by foot, as well as the distances <strong>of</strong><br />
each. Obviously the mix will change from year to year so only an average or<br />
approximation is possible. In order to get a downward biased idea <strong>of</strong> the extra<br />
vehicle costs, assume all the students travel the extra distance by bus (cheaper<br />
than private cars in cost-benefit analysis). In 2009/10 bus operating costs per<br />
kilometre in Wales were 114 pence (DfT Bus). If the same number <strong>of</strong> buses<br />
could carry the extra student the marginal costs <strong>of</strong> the present exercise would<br />
be zero, but, in the long run at least, certainly more buses would need to be laid<br />
on and the marginal costs would be positive.<br />
If 200 <strong>of</strong> the 350 hypothetical students’ journeys required more buses, with an<br />
extra average journey per day to and from school <strong>of</strong> 20 kilometres say, and an<br />
average bus occupancy <strong>of</strong> 8, the extra vehicle costs per year would be<br />
£200x20x200x1.14/8˜£110,000<br />
An alternative exercise based upon detailed consideration <strong>of</strong> particular schools,<br />
yields an annual cost larger by almost one half. The exercise as before focuses<br />
on closing one 11-16 <strong>Secondary</strong> school <strong>of</strong> 350 students. Pupils would transfer to<br />
two other <strong>Secondary</strong> schools depending on where they live. Pupils are assumed<br />
to attend their nearest school. In Appendix B are the estimates <strong>of</strong> the length <strong>of</strong><br />
the journey travelled and the travelling times.<br />
<strong>Cost</strong>s are based upon the use <strong>of</strong> buses (Arriva trains are not willing to put extra<br />
carriages on their trains at present). Single deck buses must be run because the<br />
Assembly are at present considering the abolition <strong>of</strong> the use <strong>of</strong> double-decker<br />
buses for school transport.<br />
Total cost <strong>of</strong> transporting pupils to their two new schools as described in the<br />
Appendix: £270,000<br />
11
Present costs <strong>of</strong> transporting pupils to school considered for closure by bus and<br />
train from catchment area primary schools: £107,166.<br />
Implementing the closure according to the above model therefore increases<br />
travel costs by<br />
£162,834 per annum,<br />
a considerably higher figure than the first, rather abstract, exercise.<br />
7. Local Incomes and Employment<br />
‘Proposals might have differential impacts on individuals, amongst other<br />
aspects, according to their:... geographical location.. It is important that these<br />
distributional issues are assessed in appraisals.’ H M Treasury Green Book<br />
(2003) Annex 5 s.1 p.91<br />
In addition to the obligation to ensure that expenditure is efficient and effective,<br />
spending authorities are advised to take into consideration the distributional<br />
consequences <strong>of</strong> policies, programmes and projects.<br />
<strong>Rural</strong> secondary school consolidation undoubtedly impacts upon local<br />
employment and income, in view <strong>of</strong> the distances between schools and the low<br />
incomes and part-time work <strong>of</strong> much ancillary employment. Part-time and low<br />
income workers are less likely to find it financially feasible to travel substantial<br />
distances to work regularly. Consequently, rural school closure would certainly<br />
deprive local cleaners, catering assistants, maintenance staff, lunchtime<br />
supervisors and probably classroom support workers, <strong>of</strong> sources <strong>of</strong> income.<br />
Their pay and numbers in a particular case are given in Table 2.<br />
It is true that the area in which the expanded schools are located would benefit<br />
from greater income and employment opportunities as a result <strong>of</strong> school<br />
consolidation. But authorities may not regard this redistribution as in accordance<br />
with their policies. They are not obliged to treat losses to some people as <strong>of</strong>fset<br />
by gains to others – even when the magnitudes are balanced – if a major policy<br />
concern, such as maintaining rural communities, was involved.<br />
To estimate how much income and employment might be involved each year in<br />
a rural secondary school closure, it is probably appropriate to assume teaching<br />
and more highly paid ancillary staff would be able to commute. Though this<br />
12
imposes an additional cost upon them, if they lived locally their job relocations<br />
would not much affect local incomes and employment.<br />
Taking the following ancillary staff costs (Table 2) as illustrative, even excluding<br />
the classroom assistants and those earning more than approximately £7000, the<br />
low and part-time incomes in the locality would be cut by about £74,000 a year<br />
in the event <strong>of</strong> school closure. The spending <strong>of</strong> the affected people would also<br />
support other employment – though judging by a study <strong>of</strong> Welsh National Parks<br />
this multiplier effect is small. The National Parks Study (National Trust 2006)<br />
estimated across all three parks an extra 20 percent <strong>of</strong> indirect income and<br />
within the Parks perhaps an extra 2 percent. These numbers justify adding a<br />
little on to the illustrative £74,000. The margins <strong>of</strong> uncertainty as to how much<br />
to add are considerable so here the figure is simply rounded up to £75,000 to<br />
include multiplier effects.<br />

8. Disposal <strong>of</strong> <strong>School</strong> Site<br />
When a small Primary school building becomes available, it is first <strong>of</strong>fered for<br />
community use and then in the absence <strong>of</strong> takers, placed on the open market.<br />
The building might be an pportunity for a small business premises, or a local<br />
developer might, subject to planning permission, use the site to build houses.<br />
<strong>Secondary</strong> school sites are, however, large and complex, with laboratories,<br />
gymnasiums, halls and other unusual features. They might be attractive for<br />
large developments such as supermarkets but there would otherwise be limited<br />
demands for the site in a rural community. Local developers would not be so<br />
easily attracted and any large housing development would not be popular or<br />
needed- and therefore would not be granted planning permission. The site could<br />
become a liability rather than an asset, especially in the short term.<br />
If demolition had to be considered, then these costs could be high. Some <strong>of</strong> the<br />
rural schools are also within the National Park which would present considerable<br />
planning issues for any new developments. By contrast, if a school in one <strong>of</strong> the<br />
more urban areas was considered for closure then there would be a possibility <strong>of</strong><br />
substantial gains.<br />
Since the present study estimates annual costs and benefits rather than present<br />
values, any sum from sale <strong>of</strong> the site must be converted into an annual figure.<br />
At the 3.5 percent real discount rate recommended by the Treasury, for every<br />
£100,000 <strong>of</strong> the net value <strong>of</strong> the site sold, the annual value would be £3,500.<br />
9. Educational Achievement and <strong>School</strong> Size<br />
There is evidence that many Welsh secondary schools are larger than desirable<br />
for the best educational performance (Foreman-Peck and Foreman-Peck 2006).<br />
However, schools in Gwynedd are generally below, close to, or not far above this<br />
calculated optimum. A scatter plot (figure 2) <strong>of</strong> the relationship since 2002<br />
between school size in Gwynedd and school Key stage 3 percentage score shows<br />
no relationship between the variables. On the other hand there is a relationship<br />
between school size and per pupil cost (as predicted by equation 1 Table A1)<br />
(figure 3). And the (predicted) costs per pupil appear to rise with KS3 score<br />
14
performance (figure 4). At first sight then it would seem that funding is allocated<br />
to schools so that they may maintain a target educational standard regardless <strong>of</strong><br />
their size. There appears to be no size penalty once the higher running costs <strong>of</strong><br />
small schools are taken into account.<br />
However, there is evidence <strong>of</strong> a cost penalty for achieving a given school Key<br />
Stage 3 educational standard for schools <strong>of</strong> the size <strong>of</strong> the example considered<br />
throughout this study – 350 pupils - from estimated costs function for Gwynedd<br />
schools. The interpretation <strong>of</strong> this result is not entirely clear. Ideally an<br />
educational value added measure would be related to school costs, but<br />
experiments with the %tl2 score and KS3 did not yield statistically significant<br />
results.<br />
With the KS3 score alone the results appear to show that the cost <strong>of</strong> achieving a<br />
given KS3 score not only decline with school size but are actually negative over<br />
the range <strong>of</strong> pupils 300+. This raises questions as to what the KS3 score is<br />
actually measuring. A possibility is that it is measuring an input into secondary<br />
education rather than an output; perhaps it captures the achievements <strong>of</strong><br />
students arriving from primary schools. If it does then the possibility that<br />
achieving a given standard <strong>of</strong> education is cheaper the higher the attainments<br />
<strong>of</strong> the new students makes sense, but does not indicate stronger performance <strong>of</strong><br />
larger schools and an additional disadvantage <strong>of</strong> smaller schools. But the cost<br />
functions reported in Appendix A table A1 show negative coefficient on the<br />
interaction between school size and KS3 score. One interpretation is that larger<br />
schools have catchment areas with higher achieving pupil intakes in Gwynedd.<br />
The number <strong>of</strong> schools is sufficiently small that it is not possible to distinguish<br />
this possibility from the negative marginal or average costs <strong>of</strong> KS3 score with<br />
size option.<br />
It turns out, in any case, that the apparent size penalty for achieving a given<br />
percentage KS3 score is small (Appendix A). According to the preferred equation<br />
the lower cost <strong>of</strong> achieving a given KS3 score with the larger school<br />
configuration amounts to merely £3700.<br />

10. Summary<br />
The estimated cost and benefits <strong>of</strong> the hypothetical rural secondary school<br />
consolidation are shown in Table 3 below (columns a). All <strong>of</strong> the figures in the<br />
Table are surrounded by a substantial margin <strong>of</strong> uncertainty. In the case <strong>of</strong><br />
school site disposal it is hard to arrive at a figure other than zero at all.<br />
However, with other the numbers in the table, a site net value <strong>of</strong> £2 million,<br />
when converted into a permanent annual value to be commensurate with the<br />
other figures, would not be sufficient to turn the balance <strong>of</strong> net benefits from<br />
consolidation positive in the best estimate case <strong>of</strong> columns a.<br />

determine the appropriate policy, not concerns with ‘empty places’ or ‘cost per<br />
pupil’.<br />
True efficiency involves achieving desired objectives with the least possible<br />
resource cost. It is important to recognise that there is usually more than one<br />
policy objective, more than one resource and that in these circumstances priority<br />
cannot always be claimed for policies that minimise cash outflows.<br />

Appendix A Gwynedd secondary school cost functions 2002-2010 *<br />
<strong>School</strong> costs per pupil (AC) are determined by wages (T, assumed to grow at a<br />
steady annual rate), staffing levels, school buildings, number <strong>of</strong> pupils (Q) and<br />
perhaps educational standards (<strong>School</strong> %Key stage 3 here, KS3). The following<br />
cost function is estimated from a panel <strong>of</strong> 14 schools 2002-2010, with the years<br />
2003-5 excluded.<br />
AC=a + bQ + cQ 2 + dKS3 + e KS3*Q + fT + .. + u<br />

On top <strong>of</strong> this there is the gain on 200 students from moving from a school <strong>of</strong><br />
350 to one <strong>of</strong> 500, i.e. from the first calculation £267*200=£53,400. So the<br />
total financial cost reduction from school consolidation is ;<br />
134000+171200+53400 = £358,600,<br />
broadly similar to the £350,000 calculated by visual inspection <strong>of</strong> figure 1.<br />
Turning to school quality, the extra cost <strong>of</strong> achieving a given KS3 score from<br />
having smaller schools, or the lower costs <strong>of</strong> achieving a given KS3 score with<br />
the larger school configuration, must be calculated for the cost-benefit analysis.<br />
Again using Eq.1 Table A1, the cost reduction for the school ending up with 500<br />
students is; ? AC=-.0174*150= -2.61, with ? TC=1305<br />
For the 700 pupil school ?AC = -.0174*200 =-3.48, with ? TC=-2436<br />
Therefore total quality incremental cost is merely £3700.<br />
