The purpose of this study is to investigate if there is a positive relationship between principals mentored through the NewLeaders Assistance Service and the retention of the participants who continued their career in educational administration. The participants for this study were first-year principals from 2001-2016 in the NewLeaders Assistance Service program. The NewLeaders Assistance Service was a comprehensive principal mentoring program with experienced and highly trained mentors. The program was personalized with professional development, on-going support, and individual mentoring. Results indicate that a high percentage of respondents felt the program was critical to their success in the profession with 83.5% remaining in the profession. Additional research needs to be conducted on the ongoing demands of the ever-changing political landscape over extended periods of time.
