The preschool (also called Pre-K) at Dr. William L. Cobb Elementary School serves children ages 3 through 5, and is part of the SFUSD Early Education Department and Early Childhood Special Education Services. We have one inclusive classroom and one special education classroom.


Children and families in the Early Education Department have access to high quality early childhood programs and services that promote and support the right of every young child and his or her family, regardless of cultural and linguistic background, family composition and/or ability to participate in a broad range of activities and contexts as full members of a school community. Children with and without disabilities will feel a sense of belonging and membership; create and maintain positive social relationships and friendships; and receive support for their development and learning in order to reach their full potential.
