The study proposed to determine if an 8-weeks' summer preparatory program in English, math, reading, study aids, science, and group dynamics would enable a particular group of 51 students to compete academically in the first semester of the 1968-69 school year with 51 regularly admitted students. The experimental group was chosen from those required to take the 8-week program before admittance to the college; the control group, from regular students whose academic load was limited to four courses. The pairs were matched by college board scores within plus or minus 20 points. After the summer session, students from the experimental group were enrolled in the regular session. At the end of the first semester, GPA's for both groups were analyzed by a t-test. The analysis showed that the experimental group surpassed the regular group in academic achievement, though not to a significant degree. The author concludes that the summer program is therefore worthwhile. He recommends (1) that the developmental program be continued, (2) that a follow-up study be made at the end of five years to see if the difference between the groups remains the same, and (3) that similar studies of wider scope be made to confirm or refute these findings.
