The fourth year of the Test Preparation Program for Gifted and Talented Sophomores (TPPGTS) is evaluated. This 6-week, 75-hour test coaching program was developed to teach high-achieving students principles/strategies required for doing well on the Preliminary Scholastic Aptitude Test (PSAT)/National Merit Scholarship Qualifying Test to increase the number of National Merit semifinalists and finalists. The TPPGTS emphasized language arts, mathematics, and guidance, and was conducted at the Lane, Lindblom, and Curie High Schools in Chicago, Illinois. Pretests and posttests were completed by 93 of the 148 enrollees; 72 of these took the October PSAT. The comparison group initially included 137; of these, 47 completed practice tests and 37 took the PSAT. There were nine teachers and three teacher aides in the TPPGTS. Student and teacher questionnaires and classroom observations were analyzed concerning the degree to which summer program students outperformed the comparison group from pre- to posttest and whether this effect was attributable to the program. The TPPGTS appeared to be implemented as designed; an overall positive math program effect equivalent to 42 SAT points was found. Neither general nor site-specific verbal coaching effects were seen. Students were generally satisfied with the TPPGTS and thought they had learned effective strategies. Teachers noted the diversity of instructional materials and activities, and made recommendations for improving the program. (SLD)
