Generation Y represents a growing number of student-teachers who will impact the future of educational practice, yet little research has been conducted for this demographic group. The purpose of this mixed-method study was to identify motivational factors of neophyte teachers and the retention implications these findings had on Kindergarten through 12th grade (K-12) leaders. Quantitative data were collected via a survey from 50 Generation Y, K-12, student-teachers from a private, accredited university in Ohio, and from 32 K-12 educational leaders. Quantitative data were analyzed using independent t tests and results showed statistically significant differences in 11 of the 15 motivational factors (student achievement t (47) = -4.97, p less than 0.05; having success with colleagues t (80) = 2.04, p less than 0.05; working with students t (80) = -5.41, p less than 0.05; relationships with subordinates t (57) = 5.24, p less than 0.05; being trusted with responsibility t (45)=-3.85, p less than 0.05; personal life t (80) = 2.37, p less than 0.05; career advancement opportunities t (80) = -2.03, p less than 0.05; career growth t (80) = - 3.49, p less than 0.05; yearly salary t (80) = 2.78, p less than 0.05; relationships with supervisors t (80) = -3.04, p less than 0.05; and supportive supervision t (80) = -2.22, p less than 0.05). Qualitative data were collected from eight administrators using the focus group interview model and analyzed for themes and patterns. Areas of high motivation for student-teachers, as noted in the qualitative findings, included student-centered working responsibilities, gains in student achievement, higher levels of responsibility and trust, career growth potential, and positive relationships with supervisors. Recommendations include the need for professional development training for K-12 administrators to meet identified needs of Generation Y teachers. Future research could identify generation-specific teaching applications and investigate whether these findings can be used by administrators in urban school districts to promote teacher retention.
