In 1994-95, a study identified over 50 Texas schools that were heavily impacted by poverty but had high scores on state achievement tests. Specifically, the schools received Title I funds and were implementing Title I schoolwide programs, and at each school, over 60 percent of students met free or reduced-price lunch criteria; at least 70 percent passed the reading section of the Texas Assessment of Academic Skills (TAAS); and at least 70 percent passed the TAAS math section. Case studies of 26 of these schools found much diversity in instructional programs and approaches. However, seven common areas or themes emerged: (1) focus on the academic success of every student; (2) no excuses; (3) careful experimentation; (4) inclusion of everyone in problem solving; (5) sense of family; (6) collaboration and trust; and (7) passion for learning and growing. Profiles of the 26 schools include a brief description, demographics, awards, TAAS results, and principal and teacher comments. Excerpts of case-study interviews include success stories related by parents, teachers, and staff. A self-study and planning guide draws on the seven common themes of successful schools to provide a structured process through which school communities can begin the evaluation and planning necessary for school improvement. Seven modules corresponding to the themes contain worksheets with questions to promote critical reflection and self-evaluation, goal setting, and planning. Suggested readings and a feedback form are included. Suggestions for technical assistance providers include topics and rationale for professional development. (SV)
