InquiryMasters Program forAdvancingContent forTeachers
Funded by the United States Department of Education
Goals of IMPACT• Increase the number of high quality science teachers in
Toledo Public Schools and the Toledo area by adding 20 science teachers with a MS in Biology degree.
• Maintain a minimum of 90% retention of participants.• 100% of program completers will remain as science teachers
in TPS or other high needs schools for at least two years after degree completion.
• Improve student academic achievement in science in IMPACT classrooms.
• Increase the number of secondary school students enrolled in upper level science courses by 20% in the schools where participants teach.
• Increase the number of secondary school students who plan to pursue postsecondary education in a science-related field by 15% in the classes taught by IMPACT teachers.
