This study was designed to investigate what aspects of teacher education (if any) affect student success. Questionnaires were mailed to a random sample of high- and low-performing urban and rural public high schools across Arizona. Quantitative variables that were researched include the level of degree a teacher attains, the route a teacher chooses to achieve certification, teachers’ attendance at core-subject related workshops, teacher mentoring, and teacher collaboration using data based information to drive decision-making. Qualitative research enabled teachers to state a valuable skill learned in college that promotes student success and to reveal what they felt their current school does to promote student success. A mixed methodology approach was used to analyze the data; quantitatively through regression analysis and qualitatively through coded themes.A detailed explanation was presented with accompanying data to support the statements. The results of this research support teacher mentoring and attendance at core subject related workshops as vehicles to promote student success. This dissertation provides information for policy makers, administrators, and teachers who are invested in promoting student success.
