The original purpose of the Training Future Faculty (TFF) program was to assist graduate students and post-docs with gaining teaching experience and skills. There is a greater need for these individuals to gain inclusive teaching experience, as there is an increased need for equitable teaching in STEM. Persistence in STEM education is low, especially in historically marginalized and excluded groups . This poster shares a curriculum in developing inclusive teaching, preparing a foundation for persistence in STEM, and data and reflections from mixed-methods research with TFF participants and alumni. The potential impact is increased confidence in teaching skills, improved learning climate, and retention of students in STEM fields.
