Child Outcome Summary (COS)

The purpose of Washington’s Child Outcome Measurement System (COMS) is to assure stakeholders that early intervention makes a difference for infants, toddlers and families. Families are a crucial source of information about their children, and this enhances the quality of the data. The COMS is one way for families to see their child’s progress and to give input on program improvements. The data is analyzed at state and local levels to help improve services and meet federal and state reporting requirements.
