NQF Endorsed Measures

In Janurary of 2022, National Quality Forum (NQF) endorsed 14 NCI-IDD measures. This endorsement followed a rigorous review of scientific methods, consensus panel analysis, and a public comment period. It was issued in recognition of the high demand for quality measures in home and community-based services. The endorsement is an important step toward enhancing the quality of services and supports provided to people with intellectual and developmental disabilities across state systems.
