- Sinai Preschool is accredited by the National Association for the Education of Young Children (NAEYC). We serve families with children 12 months to 5 years of age. The preschool provides a fun-filled, play-based learning environment designed to promote cognitive, social and emotional growth. We offer an opportunity to extend your childâ€™s day with an Enrichment program for those who are over the age of 3 years. The mission of Sinai Preschool is to provide high quality preschool education to our Sinai community and to the wider Chicago area by incorporating reform Jewish values and traditions within a broader, relationship-based curriculum. We are a neighborhood preschool in a Jewish setting. Our families come from a variety of religious and cultural backgrounds. We pride ourselves on introducing children to Judaism within a broader context of acceptance and respect for a multiplicity of religious and cultural experiences.
