This report represents one of two outputs from the third strand of this project which has the overall aim of developing a framework for the evaluation of Teachers’ Professional Learning (TPL). The project consists of detailed desk-based research, including a literature review (Rawdon, Sampson, Gilleece, & Cosgrove, 2020); a survey of teachers and principals in primary, post-primary, and special schools (Rawdon, Gilleece, Denner, Sampson, & Cosgrove, 2021); consultation with TPL providers (Rawdon & Gilleece, 2022); consultation with children and young people; and a case-study focusing on an evaluation of a specific TPL opportunity (in the area of student wellbeing).
