Question 2: Explain the difference between standards- (criterion-)<br />

referenced, and norm- referenced assessment, and the link between<br />

them.<br />

Two types of assessment commonly used both in schools and the wider<br />

community are norm- and standards- (criterion-) referenced assessment.<br />

These two assessment forms seem quite different: norm-referenced<br />

assessment compares individuals’ performance in relation to one another,<br />

whereas standards-referenced assessment focuses on whether the set criteria,<br />

or standards, have been met. However, there is a relationship between them,<br />

as assessment is often both standards- and norm-referenced. In the following,<br />

I will explain in more detail the difference between norm- and standardsreferenced<br />

assessment, and the link between them. It is my conclusion that<br />

both forms of assessment are useful and valid, although to different extents<br />

depending on the context in which learning and teaching takes place.<br />

Norm-referenced assessment emphasises the individual differences of learners.<br />

As Biggs and Telfer (1987, p. 137) explain, ‘in norm-referenced evaluation, the<br />

final grade … is determined by how well the student compares with other<br />

students in the class.’ Learners may also be compared with established norms<br />

of achievement, such as student performance in previous years or students<br />

from another class or school. Norm-referenced measures are most useful when<br />

we want to compare individuals’ results, and often those students are given a<br />

ranking as a result. Consequently, norm-referenced evaluation emphasises<br />

competition (Biggs and Telfer, 1987, p. 137). The most prominent example of<br />

this in Western Australian schools are the Tertiary Entrance Examinations (TEE)<br />

where all students are given a competitive Tertiary Entrance Rank (TER).<br />

Smaller scale teacher measurements may also be norm-referenced. As<br />

McInerney and McInerney (1998, p. 298) describe, ‘whenever a teacher<br />

compares an individuals’ score with the average score of the class on an<br />

activity, he or she is using a norm-referenced approach’. These scores do not<br />

give specifics about what learners actually did, but represent students’<br />

achievement in relation to the standardising group at the time.<br />

A criticism of norm-referenced assessment is that the distribution of scores is<br />

generally made to follow a bell shaped curve. This is problematic because<br />

learners who perform objectively no worse than other learners in previous years<br />

or other classes may be graded lower just because their particular reference<br />

group scores higher (McInerney and McInerney, 1998, p. 298). Additionally, in<br />

order to be fair and valid, norms should reflect the background cultural, social<br />

and learning experiences of the individuals being tested. Unfortunately, this is<br />

rarely the case (McInerney and McInerney, 1998, p. 298).<br />

An alternative to norm-referenced assessment is standards-referenced<br />

assessment. This is also called criterion-referenced assessment because the<br />

focus is on whether or not learners have satisfied the set criteria. The criteria<br />

should be explicit, and may be individualised to take into account a range of


learner characteristics (McInerney and McInerney, 1998, p. 299). Criteria may<br />

also be set for a whole class (i.e., are syllabus-specific), and scores generally do<br />

not follow a bell shaped curve. Furthermore, standards-referenced assessment<br />

does not place an emphasis on competition, and often gives specifics about<br />

student achievement and progress: very useful in formative evaluation<br />

processes.<br />

Forms of evaluation that assesses whether students have achieved a particular<br />

outcome of the Curriculum Framework (1998), and to what level as indicated by<br />

The Curriculum Framework Progress Maps (2003) are examples of standardsreferenced<br />

assessment. Teachers may use a range of assessment strategies to<br />

determine whether students have met the criteria of a particular level, and<br />

hence are ready to progress to the next stage. In a multi-levelled classroom,<br />

standards-referenced assessment is often more valid than norm-referenced: if<br />

one student is working at level two and another at level four, it hardly seems<br />

fair to award them grades based on a norm-referenced approach.<br />

One link between standards- (criterion-) and norm-referenced assessments is<br />

that tests may be both standards- and norm- referenced. A student may be<br />

assessed against set criteria, but their evaluation is influenced by comparison to<br />

the work of other students. For example, this assignment has set criteria<br />

concerning whether the question has been addressed, structure, referencing<br />

and so on. However, some students may answer their chosen question better<br />

than others, and thus be awarded a higher grade according to their<br />

comparative performance.<br />

Another link between standards- and norm-referenced assessments is that<br />

criteria are often set according to the comparative work of individuals, i.e.,<br />

using norm-determined standards (Biggs and Telfer, 1987, p. 467).<br />

Theoretically in standards-referenced assessment, criteria should be set before<br />

the learning takes place and the task completed. If they are set afterwards, the<br />

criterion becomes less of a criterion than a norm (McInerney and McInerney, p.<br />

299). In many cases, the issue is one of emphasis (E244 Unit Materials, 2003,<br />

p. 1.6).<br />

Therefore, although norm- and standards-referenced assessments take quite<br />

different approaches, there is a strong relationship between them – they are<br />

constructed using similar criteria, and the extent to which an assessment is said<br />

to be norm- or standards-referenced may only be one of emphasis. In K-10<br />

classes, it is increasingly more common for teachers to use criterion-referenced<br />

assessment due to the outcomes-based nature of the curriculum. However,<br />

students are often compared to one another and competitive ranking occurs.<br />

Furthermore, due to the nature of the TEE, TEE students generally undertake<br />

more norm-referenced assessments than standards-referenced, and criteria are<br />

often norm-determined standards. Since the Curriculum Framework (1998)<br />

emphasises that judgements on student progress must be based on multiple<br />

kinds and sources of evidence, the use of both norm-referenced and standardsreferenced<br />

assessment in the classroom is pedagogically sound, although one


may be more ‘valid’ than the other, depending on the learning and teaching<br />

context.<br />

Explain the concepts of validity and reliability showing why they are<br />

important in assessment.<br />

Assessment is an essential component of the learning and teaching process,<br />

and in order to find out what students know, value and are able to do as a<br />

result of their schooling, that assessment must be valid and reliable. In the<br />

following, I will briefly explain the concepts of validity and reliability showing<br />

why they are important in assessment. The reliability and validity of<br />

assessment is central to its usefulness for….<br />

As LeFrancois (1997, p. 469) explains, ‘probably the most important<br />

characteristic of a good test from the students’ point of view is that it be fair.<br />

Indeed, fairness is emphasised throughout the Curriculum Framework (1998),<br />

and in order to be fair, assessment must first be valid. Assessment is valid if it<br />

measures what it is intended to measure (LeFrancois, 1997, p. 469), and many<br />

types of evidence should be accrued to support the validity of those<br />

measurements (McInerney and McInerney, 1998, p. 293).<br />

There are four main types of validity in assessment: face validity, construct<br />

validity, content validity and criterion-related validity. The first, face validity,<br />

refers to whether or not the assessment appears valid on the surface. That is,<br />

it looks like it is supposed to. A maths test should look like a maths test, and a<br />

language test should follow a format familiar to language students and so on.<br />

It needs to be explicit on the face of things what is expected in the assessment<br />

in order for it to be valid (E244 Unit Materials, 2003, p. 3.3).<br />

Construct validity is often seen as ‘the essential kind of validity’ (E244 Unit<br />

Materials, 2003, p. 3.1), overarching all other aspects of validity. Indeed, it<br />

may be said that face, content and criterion validity are evidence for construct<br />

validity (E244 Unit Materials, 2003, p. 3.0). In order for assessment to have<br />

construct validity, all components of the test must reflect the intended<br />

construct.<br />

A test may be reliable, but not valid.
