Getting children ready to learn and thrive - Research into implementing effective and quality Early Childhood Development at scale The THRIVE Early Childhood Development research programme will deliver research on how to implement effective ECD interventions at scale in LMICs. Through an innovative model of research co-designed and aligned to DFID country programmes, THRIVE will support four DFID bilateral programmes to improve the effectiveness and efficiency of ECD interventions emdedded in their education and human development programmes, and commission globally-relevant research into optimal ECD service delivery and scale up strategies. Through the proposed COVID-19 pivot, the programme will generate real time evidence on impact of Covid-19 on young children's learning and development, and test at scale innovation on approaches to mitigate the crisis of learning and care. This programme directly responds to the manifesto commitment on girls' education.
