- 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 child’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.
