As states and territories make decisions about child care policies, they may find it useful to collect data from child care providers. Existing administrative records, such as child care licensing data or workforce registries, offer answers to many questions but may be limited. New data—in the form of surveys, interviews, or focus groups—are useful to answer questions about providers’ motivations, experiences, and perceived benefits and challenges of programs and policies. Surveys can collect important information from providers but can be difficult to create. For example, poorly worded questions can lead to inaccurate and unusable survey responses. This brief describes best practices for developing and testing a survey of child care providers (see appendix A for glossary of bolded terms). (author abstract)
