* Smaller group sizes and lower staff/child ratios have been found to be strong predictors of compliance with indicators of quality such as positive interactions among staff and children and developmentally appropriate curriculum. Variations in group sizes and ratios are acceptable in many cases where the program demonstrates a very high level of compliance with criteria for interactions (A), curriculum (B), staff qualifications (D), health and safety (H), and physical environment (G).
