The purpose of this mixed-methods study was to evaluate the efficacy of 14 Mathematics, Science and Technology Teacher Preparation (MSTTP) academies located across the state of Texas. The aim of the academies was to increase the number of highly qualified mathematics, science and technology teachers, while also improving the quality of certified teachers in these areas by focusing on seven established goals. A mixed-methods design was utilized to analyze both quantitative and qualitative data. The results revealed that the 14 MSTTP academies demonstrated three key strengths: focusing on strengthening content knowledge; developing professionally committed teachers; and providing funding for participants. Additionally, all 14 academies were charged with accomplishing seven goals; however, none of the academies fully implemented all of these goals. Specifically, all of the academies struggled to accomplish two goals: the integration of the areas of science, technology and mathematics; and the infusion of technology into curriculum. Finally, the study revealed that the goal of strengthening content knowledge was a good predictor for participants' content qualifications, while strengthening content knowledge and strengthening pedagogical skills were good predictors of participants' pedagogical qualifications. This research study contributes to the fields of teacher preparation and professional development.
