The State Family Outcomes Measurement System Framework (S-FOMS) is a framework originally developed by the Early Childhood Outcomes (ECO) Center that identifies seven key components of a high-quality family outcomes measurement system at the state level. This document contains background information about the framework's seven components, 15 quality indicators, and their associated elements of quality. The framework is intended to assist states in developing a measurement system that captures various aspects of family outcomes and experiences, such as the benefits that families receive from program participation, family satisfaction with services, perceived helpfulness of the services, and family involvement with the service delivery system. The S-FOMS and two related resources were developed for state Part C and Part B 619/Preschool programs to evaluate and improve their family outcomes measurement system. The ECO Center had developed the original Family Outcomes Measurement Framework (FOMS) in 2011 for state use. It was renamed the S-FOMS in November 2017 to align the naming convention with a similar framework for child outcomes, the State Child Outcomes Measurement System (S-COMS) framework.
