In December 2015, Kate Williams (Aberystwyth University) and Katy Holloway (University of South Wales) were commissioned by Welsh Government to undertake an evaluation of Phase 1 of the pilot of the Young Persons’ Outcome Monitoring Tool (YPOMT). The results of the evaluation are presented in this report. The Executive Summary provides both an overview of the background to the pilot and a summary of the methods used in the evaluation, highlights the key findings and makes tentative suggestions to guide Phase 2 of the pilot.
