The purpose of this study was to compare the results obtained from four methods for estimating reading potential when they were applied to twenty-nine high ability eighth grade students. The estimates were obtained by using the Bond and Tinker formula, the Harris Reading Expectancy Age formula listening capacity level, and the Analysis of Learning Potential Test. The Peabody Picture Vocabulary Test was administered to identify high ability students, and an informal listening inventory was administered to define listening capacity level as an estimator of reading potential. The Reading Prognostic Subtests of the Analysis Learning Potential Test were administered to provide estimates of reading potential. The estimates of reading potential obtained from the Bond and Tinker formula closely approximated high ability eighth grade students' reading achievement levels. The Harris Reading Expectancy Age formula provided estimates of reading potential which averaged 0.7 of a grade level higher than students' reading achievement levels. Listening capacity estimates were approximately one and one-half grade levels higher than students' reading achievement levels. (Author/WR)
