2.5.3. Adolescent academic aptitude

PT60 included tests of vocabulary, English language mastery, reading comprehension, logical reasoning, creative problem solving, math concepts, math reasoning, elementary algebra, fractions, percents, basic geometry, and square roots. Combined, these elements comprised PT60's general academic aptitude composite with 829 total possible points. We standardized this score. These academic tests were developed using past research and experience in test construction. After detailing test specifications, items were constructed and piloted in a group of schools. Statistical analysis of the pilot test items led to decisions regarding which items to maintain and how to improve items if necessary (for more information on sources and processes see (Flanagan, 1962)).
