3.5 Statistical Analysis of <strong>Pupil</strong> Attainment Data: Data Sources,<br />

Collection <strong>and</strong> Processing<br />

A small scale study explored the impact of the increase in IWB acquisition on pupil<br />

performance in the core subjects using data on the number of IWBs in departments<br />

in October 2003 <strong>and</strong> October 2004 <strong>and</strong> timetable data collected directly from<br />

schools. <strong>The</strong>se were combined with pupil-level attainment data from the National<br />

<strong>Pupil</strong> Database. This combination of data was successfully collected for 9% of<br />

London schools <strong>The</strong> data were used in separate sets of regressions to analyse<br />

whether changes in the ‘value-added’ achieved at school level, at teacher level <strong>and</strong><br />

by departments at KS3 <strong>and</strong> KS4 between 2003/04 <strong>and</strong> 2004/05 could be due to the<br />

increase in the number of IWBs in departments. <strong>The</strong> small scale study concluded<br />

that there was no evidence of any impact, positive or negative, of increased IWBs in<br />

subject departments on attainment at KS3 <strong>and</strong> KS4 in Maths, Science <strong>and</strong> English.<br />

This conclusion was corroborated by estimating the change in London schools’ value<br />

added in these subjects between 2004 <strong>and</strong> 2005. <strong>The</strong> positive <strong>and</strong> negative changes<br />

in some of the subject value added estimates found in the small scale study mirrored<br />

the general trend in value added changes between the two years for London schools<br />

compared to schools nationally. Full details of the analysis will be found in Section 8<br />
