This study determined the laboratory school’s performance and developed a three-year strategic plan to enhance its organizational performance. The researcher used a descriptive survey design, and the survey results were analyzed using frequency count and mean. The participants consisted of the school management, alumni, faculty, nonteaching staff, and students. Purposive sampling was used to select 101 participants within a school year for the study. The analysis and synthesis of data showed that the areas that needed attention were reducing the number of students per class, formulating faculty development programs, conducting in-service training, and hiring competent teachers. Further, developing the laboratory school’s purpose, values statement, objectives, key improvement strategies conducting operational research, publication of research studies, funding for faculty research, providing incentives for researchers, and preparing the vision-mission for the laboratory school are recommended in this study. These findings are addressed in the strategic plan developed for review and approval of the management committee to achieve organizational effectiveness and raise the performance of the laboratory school. Finally, this study may ensure the continued operation of the laboratory schools in state universities and colleges.
