“…There are a number of studies that examine associations among aggregate quality ratings from QRIS, which typically average multiple indicators of quality (e.g., child-adult ratio, global environment) across multiple classrooms into one rating. Across a number of different state QRIS, there is little evidence of associations between quality ratings and children's outcomes (Karoly, Schwartz, Setodji, & Haas, 2016;Sabol, Hong, Pianta, & Burchinal, 2013;Sabol et al Thornburg et al, 2009;Zellman, Perlman, Le, & Setodji, 2008). However, it is unclear whether average center quality on each of the quality measures included in the QRIS ratings relates to children's outcomes.…”
