This study applies a procedure which yields estimates of true score change on the Scholastic Aptitude Test (SAT) adjusted for regression effects and student self-selection. It is shown that student self-selection in deciding to repeat an admissions test probably involves factors in addition to the measurement error attributable to variations in aspects of test specifications and to variations in responses of test candidates across forms, and that estimated true score change remains nearly constant across initial score levels in contrast to the negative slope of observed score change across initial score levels.
