Background identification of children at risk of developmental delay and/or impairment requires valid measurement of early child development (ECD). ECD measurement tools were systematically assessed for accuracy and feasibility for use in routine services in low income and middle-income countries (LMIC).
Building on World Bank and peer-reviewed literature reviews, available ECD measurement tools for children aged 0–3 years used in ≥1 LMIC were identified and matrixed according to when (child age) and what (ECD domains) they measure at population or individual level. Tools measuring <2 years and covering ≥3 developmental domains, including cognition, were rated for accuracy and feasibility criteria using a rating approach derived from Grading of Recommendations, Assessment, Development and Evaluations
