Abstract
Criterion-referenced assessment has made promises that it is unable to keep. The idea that a criterion-referenced test may afford a clear and direct interpretation in terms of exactly which tasks an examinee can perform is unattainable for the kinds of learning promoted in complex curricula, such as the National Curriculum in England and Wales. However, examining more carefully the origin of these claims suggests that they reflect a particularly narrow view of criterion referencing, founded on some dubious assumptions. A reanalysis of the notion of criterion referencing shows that there are advantages to adopting an approach that references assessment outcomes to an underlying educational construct, not only in clarifying how those outcomes should be interpreted, but also in terms of manageability. The introduction of level descriptions for National Curriculum assessment is discussed in relation to this approach.
