Yen, Wendy M. – 1982
Test scores that are not perfectly reliable cannot be strictly equated unless they are strictly parallel. This fact implies that tau equivalence can be lost if an equipercentile equating is applied to observed scores that are not strictly parallel. Thirty-six simulated data sets are produced to simulate equating tests with different difficulties…

Jaeger, Richard M. – 1980
Five statistical indices are developed and described which may be used for determining (1) when linear equating of two approximately parallel tests is adequate, and (2) whan a more complex method such as equipercentile equating must be used. The indices were based on: (1) similarity of cumulative score distributions; (2) shape of the raw-score to…

Angoff, William H.; Schrader, William B. – 1982
In a study to determine whether a shift from Formula scoring to Rights scoring can be made without causing a discontinuity in the test scale, the analysis of special administrations of the Scholastic Aptitude Test and Chemistry Achievement Test and the variable section of an operational form of the Graduate Management Admission Test (GMAT) is…

In October 1981, the Graduate Record Examinations (GRE) Program introduced a new version of the General Test (GT) that differed from the previous version in three major ways. The GT was altered to: reduce the verbal measure's speededness and allow the addition of several quantitative items; delete two item types from the analytical measure; and…

Angoff, William H.; Schrader, William B. – 1981
The purpose of this study was to determine whether it would be possible to equate rights-scored to formula-scored tests without causing a discontinuity in the meaning of the score scale. Several other subsidiary studies--of the characteristics of the two scoring methods, of nonresponse and guessing, and of reliability and parallelism--were also…

Lenel, Julia C.; Gilmer, Jerry S. – 1986
In some testing programs an early item analysis is performed before final scoring in order to validate the intended keys. As a result, some items which are flawed and do not discriminate well may be keyed so as to give credit to examinees no matter which answer was chosen. This is referred to as allkeying. This research examined how varying the…
