This brief is part of a series of three briefs which aim to document technical assistance (TA) within the DFID-funded Technical Assistance for Nutrition (TAN) programme, particularly exploring best practices and lessons learned from TA provision. The first brief considered TA ways of working within the TAN project and a third brief explores the value of TA provision within countries. This, the second brief, aims to explore the landscape of TA provision by the TAN partners, unpacking common TA themes and reflections on trends within TA provision during the four years of the TAN programme.
