This study was designed to ascertain whether group achievement test data can determine special education referral accuracy. One hundred eighty-nine special education referrals from four school districts in Texas were examined. The demographics were limited to group achievement test data: grade equivalents and percentiles in the subject areas of reading, spelling, language arts, and mathematics. Also examined were referral and eligibility outcomes to special education.

The purpose of the study was to compare the relative benefits of treating at-risk students, those considered to be potential dropouts, by separating them into special classes at a separate facility—a pullout program—versus having them remain in regular classes with periodic supplemental counseling based upon individual needs—a mainstream program. To carry out the purpose of the study, students enrolled in the two types of treatment programs were compared in respect to retention in school, attendance, academic achievement based upon pretest and posttest scores, report card grades, and attitude toward school.
