The Iowa Quality Preschool Program Standards (IQPPS) represent an essential component of providing young children with early learning experiences that support the foundation for positive child outcomes and success. The implementation of IQPPS and criteria is part of continuous improvement efforts for districts and their community partners and is an ongoing process. Districts must routinely review the preschool program policies, procedures, and data to assure the programs are meeting the IQPPS and criteria. Programs may collect evidence to inform continuous improvement processes. Resources and tools have been developed to support implementation of IQPPS and criteria and continuous improvement of preschool programs.
