The Together for Early Childhood Evidence (T4ECE) project aims to make progress on early childhood education (ECE) systems in Africa by supporting cross-country learning and a better use of data and measurement for decision-making. In October 2022, T4ECE hosted a two-day workshop in Mauritius. Project participants had the opportunity to exchange experiences, learn from each other, and initiate the development of action plans to further their ECE data and measurement work in their countries. This brief focuses on key insights and lessons gleaned from the Mauritius convening that took place in October 2022. A full summary of the event can be found here.
