The purpose of this mixed methods study was to examine the impact of the quality of facilities on the educational environment in high schools located in northeast Texas. The intent of this research study was to determine the relationship between school facilities and the school-learning environment. This study was a mixed method research that used questionnaires and interviews to identify and appraise school facilities and learning environment. The problem was that school facilities were negatively impacting student learning and faculty, and administrators were not properly supporting stronger facility management.

This study used descriptive statistics to analyze the data. The independent z-test was conducted to determine the difference in student performance before vs. after the new facility. The results of the data analysis findings indicated that quality and educational adequacy of educational facilities were statistically significantly associated with student performance and teacher turnover rate showing a statistical change also.
