There are various resources at the London School of Hygiene & Tropical Medicine (LSHTM) for training in process evaluation. The School's module on Evaluation of Public Health Interventions includes teaching on process evaluation.

An important resource is the UK Medical Research Guidance to Process Evaluation. It offers a comprehensive review of process evaluation theory and a practical guide on the planning, design, conduct, reporting and appraisal of process evaluations of complex interventions. A summary article (Moore et al 2015) can be found in the BMJ, and the full guidance is available on the MRC website.
