The evaluation of Minnesota's 11 demonstration sites for the Teacher Assistance through Mentorship Program included 3 activities: on-site visits in which an evaluator interviewed 10-15 persons in each project; administration of the Teacher Mentoring Scales to mentees and mentors; completion of the Minnesota Mentorship Survey by mentees, mentors, principals, and board/advisory committee members. All sites interpreted their data, and an evaluator prepared a data report for each of the sites plus a combined report. Teams from the 11 sites, along with the mentorship task force, met in workshops with the evaluator to review the data, identify accomplishments and problems, and plan changes. The greatest impact of the program was on the mentees' understanding of teacher roles and responsibilities. The impact was slightly less on teaching performance and personal development. The specific influence of the mentor was greatest on the mentee's development as a person; impact on the mentee's teaching performance was less than expected. One-to-one mentoring was the key to success, and support for the program by school administrators was positive. Data are presented on mentoring outcomes, mentee-mentor relationships, Teacher Mentoring Scales, components of the mentorship program, training and support for mentors, preferences for one or two years of mentoring, and leadership and support for the mentorship program. Summaries of accomplishments and disappointments for the public school districts involved are included. (SM)
