This article suggests that mechanical application of Golden Rule-like procedures is inappropriate. The fundamental idea embodied in them, namely, that of taking issues of equity into account in test construction, may reasonably be done without doing violence to test validity. (JAZ)

This article discusses the application of the Golden Rule procedure to items of the Scholastic Aptitude Test.

This synopsis of the Committee on Ability Testing report (see ED 213 770 and ED 213 771) discusses recent controversy over testing limitations, test fairness, admissions testing, test disclosure, and test use in public schools to improve substandard performance. (CM)

This article rebuts comments by G. R. Anrig (1987) on the Settlement Agreement that resolved the racial discrimination suit brought by the Golden Rule Insurance Company against the Educational Testing Service (ETS) and the Illinois Department of Insurance. (TJH)

A broad description is given of admissions procedures to Israeli universities. In Israel, a single unified test, the Psychometric Entrance Test, is used for admission to the various universities.
