We are pleased to offer eight Key Indicators that together lead to high-quality family engagement in early childhood care and education settings. This research-based resource is part of a series designed to support early childhood state systems-building efforts to advance family engagement. You can link the Key Indicators of family engagement to QRIS Indicators and Standards in any phase of QRIS development. The Key Indicators may also be useful in informing state policy and systems change efforts that increase family engagement opportunities. You can choose to use the Key Indicators in ways that best address families' unique strengths and interests, state contexts, and local circumstances. (author abstract)
