Tetra Tech’s Evaluation and Research team will be sharing our expertise and knowledge at the upcoming UK Evaluation Society conference themed Bridging the gap: evaluation to action.
With extensive experience in delivering large complex multi-country, multi-sector, multi-project monitoring, evaluation and learning programmes, our monitoring, evaluation, research and learning specialists are joining the discussion on how evaluation can help drive real-world change at the UK Evaluation Society conference 2026.
Our colleagues will present three insightful sessions, drawing on our range of expertise, skills, thematic knowledge and lessons from programmes such as the FCDO-funded Somalia Monitoring Programme III (SMPIII), Monitoring Evaluation Research and Learning in Yemen Programme (MERLY) and wider scaling assessments work. We will provide insights on how evaluation can inform decision-making, adapt programming in complex contexts and support meaningful policy and programme change.
