Score Linking Issues Related to Test Content ChangesThis chapter addresses issues of score scale continuity in the event of changes to a test. A testing program needs to evolve from time to time to strengthen its alignment with school reform, curriculum changes, and changes in the test-taking population.

Some Further Thoughts on ConcordanceBoth preceding chapters in this part treat the limitations of concordance tables (tables that relate scores on tests that measure similar, but not identical, constructs). Dorans and Walker (Chapter 10) discussed requirements for equating and statistical indicators of concordance quality.

A Framework and History for Score Linkingor scaled scores (Angoff, 1971). Linking transformations can be developedin a variety of ways that reflect the similarities and differences between thetests as well as the uses to which the links are to be put.

Data Collection Designs and Linking Procedures more statistically based linking functions that relate scores on one test or form to scores on another test or form. The purposes of the present chapter are to describe commonly used designs for collecting data and statistical procedures for linking scores.

Sizing Up Linkagescan be of different types. For example, any score can be predicted from any other score(s) via an asymmetric regression equation. Alternatively, symmetric relationships can be established between pairs of scores, given the correct data collection designs.
