The Effects of Repeaters on Test Equating.
Andrulis, Richard S.; And Others
The purpose of this investigation was to establish the effects of repeaters on test equating. Since consideration was not given to repeaters in test equating, such as in the derivation of equations by Angoff (1971), the hypothetical effect needed to be established. A case study was examined which showed results on a test as expected; overall mean was lower for repeaters. Applying these data to the available equating equations, it was shown that an additional 3 percent of the examinees was categorized as having "passed" than should if repeaters were taken into account. The practical solution offered is to hold separate the score of repeaters, execute the equating on the others, and then apply the conversion to all the examinees. (Author)
