QRIS quality standards are used to assign ratings to programs that participate in QRIS, providing parents and the public with information about each program's quality. States typically use licensing standards as the starting point, or base, of the system, on which higher levels of quality standards are built. Every QRIS contains two or more levels of standards beyond licensing, with incremental progressions to the highest level of quality as defined by the State. Systems vary in the number of levels and number of standards identified in each level. The types of standards used by QRIS to assign ratings are based on research about the characteristics of programs that produce positive child outcomes. The following tables provide the Web sites for States' QRIS standards compiled by the National Center on Child Care Quality Improvement (NCCCQI). (author abstract)
