Intended primarily for secondary school administrators, teachers, and counselors, this booklet summarizes the information available, as of 1965, about the ways special coaching or tutoring may affect students' scores on the College Board's Scholastic Aptitude Test (SAT). Coaching refers to the variety of methods used in attempting to increase, in a relatively short time, students' mastery of the particular skills, concepts, and reasoning abilities tested by the SAT. Seven studies of the effects of coaching on SAT scores are summarized; four of these studies were conducted by Educational Testing Service for the College Board. The subjects varied in ability and academic background; they included public, private, and vocational high school students. The amount of coaching, instructional materials used, and coaching experience of tutors also varied. The net result across all studies was that score gains directly attributable to coaching were, on the average, fewer than ten points--a difference of such small magnitude on the SAT score scale of 200 to 800 that the College Board considered it unreasonable to expect it to affect college admissions decisions. The magnitude of the gains resulting from coaching were always small, regardless of the coaching method used or the differences in the students coached. (Author/GDC)
