This document describes what quality rating systems (QRS) are, why they matter, and how to advocate for them in early care and education. Quality is defined by five core elements: (1) standards, (2) accountability, (3) outreach to programs and providers, (4) financing incentives specifically linked to the standards, and (5) parenting education to empower families to use the QRS effectively. Research indicates that QRS can provide an accurate graded indicator of program quality.
