IQ SCORES WERE AVAILABLE FOR 97 PERCENT OF THE PUPILS ENROLLED IN GRADE 10A IN PHILADELPHIA. THE MEDIAN IQ OF PUPILS REPEATING GRADE 10A WAS 93. THE MEDIAN IQ FOR PUPILS NOT REPEATING GRADE 10A WAS 98. WHILE ONLY 37 PERCENT OF THE PUPILS WERE ENROLLED IN COLLEGE PREPARATORY CLASSES, THE COLLEGE PREPARATORY STUDENTS REPRESENTED 88 PERCENT OF THE PUPILS WITH IQ'S OF 110 AND ABOVE, AND 46 PERCENT, IQ'S BELOW 90. STUDENTS WITH HIGHER IQ'S WERE ENROLLED PRINCIPALLY IN AN ACADEMIC CURRICULA, STUDENTS WITH AN IQ BELOW 90 WERE IN INDUSTRIAL ARTS PROGRAMS. INDIVIDUAL SCHOOLS SHOULD MAKE A STUDY OF THE IQ DISTRIBUTION WITHIN THE CURRICULA OFFERED TO DETERMINE IF THE NEEDS AND LIMITATIONS OF THEIR STUDENTS ARE BEING MET. ALTHOUGH IQ CANNOT BE TAKEN AS THE SOLE CRITERION FOR INDIVIDUAL PLACEMENT, THE PERCENTAGE OF PUPILS WITH HIGH IQ'S OR WITH LOW IQ'S GIVES A FAIRLY ACCURATE ESTIMATE OF THE PERCENTAGE OF PUPILS LIKELY TO SUCCEED IN EITHER COLLEGE OR NONCOLLEGE PREPARATORY COURSES.
