This report presents a comprehensive overview of the intents, activities, and results of the New York State Mentor Teacher-Internship (MT-I) Program. Part 1 provides an introduction and overview of the evaluation study; it includes information regarding the purpose of the study, the study design and analysis, and the issue of confidentiality. Part 2 focuses on the nature of the pilot mentor-intern projects--their goals, structures, and resources--and a variety of issues that are related to developing and sustaining a local project. The third part deals with the mentor-intern relationship specifically; it provides information on who the mentors and interns were, on how the matches between mentors and interns were made, how the relationships formed and grew, what the mentors and interns did together or individually, and other issues related to this central feature of the MT-I Program. Part 4 focuses on the impact the local projects have had on participants and other educators in the local setting, as well as on the school as an organization. The final part draws a set of conclusions from the three middle parts, and on that basis offers a set of recommendations regarding future policy, planning, and practice related to the work of the MT-I Program.
