Although scholarship and research have demonstrated that achievement disparities continue to be a major area of concern in public schools, an inadequate amount of research has examined how culturally responsive professional development can impact teachers' awareness of their implicit bias and a deficit perspective of disenfranchised students. Nor is there sufficient research that examines how this type of transformative learning is associated with teaching for equity, diversity, and social justice. This Interpretative Phenomenological Analysis (IPA) explored the transformative learning experiences of teachers that participated in a cultural proficiency professional development (CPPD) program and examined how these experiences impacted teachers' implicit bias, previously unquestioned assumptions and belief systems. The study provides an asset-based solution to the achievement disparities that exist between African American and Latino students and their White and Asian Counterparts in public schools. Results indicated that exposing teachers to culturally relevant professional development facilitates transformative learning. Teachers in this study demonstrated that their experiences in a CPPD program shifted their belief systems and transformed their practices both in and outside of the classroom. After discussing the findings, implications for practice, theory, and research are offered.

I love you all dearly, thank you for being you. Finally, I could not have survived this program without my village. I have the most amazing network of friends. This type of work is so involved that it would have been impossible to accomplish without support. Thank you my friends for helping with carpooling, school functions, keeping my kids busy when I couldn't, girl's nights when I needed a break, and your encouragement and kind words when I needed a pick-me-up. I am blessed to have such an amazing group of women in my life. The old adage "it takes a village" could not have been more true for me these last five years! Thank you, I am forever indebted to you all.
