Building on the draft literature review and conceptual framework for the Home-Based Child Care Supply and Quality (HBCCSQ) project, we reviewed the existing measures and indicators important for understanding quality in HBCC. This review was designed to answer two key sets of research  questions: 1. How well do existing quality measures and sets of indicators measure the features of HBCC quality? What is the validity and reliability of current measures and sets of indicators? What procedures are used to engage, assess, and support HBCC providers? 2. What measures, indicators, or tools are needed to assess the features of HBCC quality in ways that provide reliable and valid data, and are affordable and feasible for the end users (including researchers, professional development providers, and accountability systems)? This compendium gives the CCEE field an overview of existing measures and indicators for assessing HBCC quality. It includes detailed profiles of measures and indicators that could be used for various purposes, such as conducting process and implementation evaluations, informing professional development, and pursuing other initiatives to improve quality in HBCC settings.
