The REACH-6 program was a concerted effort by the Houston (Texas) school district to revamp the instructional quality in six of its elementary schools, with the primary purpose of improving the schools' student academic performance. This report describes the academic performance of the students in the REACH-6 program on the TEAMS and MAT-6 tests between 1986 and 1989. Several instructional activities, resources, and educational opportunities were offered to schools in order to facilitate the following improvements: (1) the development of effective building level leadership; (2) the use of effective teaching strategies; (3) the infusion of high expectations into the schools; (4) the improvement of student motivation to learn; and (5) the enhancement of parental involvement in school activities. The findings for each school are discussed separately; and each grade cohort, from third through fifth, is also discussed separately. The following evaluation points are addressed in this report: (1) the percentages of students passing the TEAMS each year; (2) the changes in the percent of students passing the TEAMS each year; (3) statistically significant differences between 1986-87 and 1988-89 TEAMS passing rates; and (4) the mean grade equivalent scores of the students each year. Overall, the findings indicate that the program was instrumental in improving the performance of students in the program schools. Generally, it seems that the grade that had the largest gains from the program was the third grade cohort. Twelve figures and 12 tables are included. (JS)
