While measurement precision is relatively easy to establish for single tests and assessments, it is much more difficult to determine for decision making with multiple tests on different subjects. This latter is the situation in the system of final examinations for secondary education in the Netherlands and is used as an example in this paper. This…

The purposes of this paper are five-fold to discuss: (1) when item response theory (IRT) equating methods should provide better results than traditional methods; (2) which IRT model, the three-parameter logistic or the one-parameter logistic (Rasch), is the most reasonable to use; (3) what unique contributions IRT methods can offer the equating…

This paper looks at some of the problems arising from the procedures used by the Queensland, Australia, Board of Secondary School Studies to compile percentile scores known as Tertiary Entrance Scores. Although efforts to equate across schools and across subjects are being challenged, at present there is no alternative. (LMO)

Although there are many advantages to using computer-based tests (CBTs) linked to computer-based instruction (CBI), there are also several difficulties. In certain instructional settings, it is difficult to conduct psychometric analyses of test results. Several measurement issues surface when CBT programs are linked to CBI. Testing guidelines…

A specific application of test equating is described, namely that of credentialing examination programs in the health professions. Considered are: (1) the role of test equating in the credentialing process; and (2) the issues that must be considered when implementing test equating in a credentialing examination program.
