In May 2021, Global Partnership for Education (GPE) Knowledge and Information Exchange (KIX) launched the project, Strengthening In-service Teacher Mentorship and Support, which involves a teacher support model called School-based In-service Teacher Training (SITT) in Kenya, Tanzania, and Zambia.
SITT is a practice-based approach that involves training experienced teachers and college tutors to mentor other secondary school teachers through peer learning exchange, model lessons, and team teaching. It has now published various reports on its findings.
