Over the last year or so, several countries and programs have developed service standards for their OVC programs in order to improve the quality of services provided to children, and address the variation in, and lack of equity among, OVC service providers on what constitutes “an OVC served.” These draft standards are an important step in improving OVC programming and reflect current practice, common sense, and the collective wisdom of people involved in programs. Yet, the evidence base that the application of these standards will result in improved outcomes for vulnerable children is very thin. This document outlines a suggested strategy that programs and countries could use to strengthen the standards themselves and knowledge about how best to implement them. It will also expand the evidence base that other countries and programs can use to improve their own OVC programs.
