Building Blocks Developmental Preschool has been providing programs and services to young children and their families since 1984. Presently we offer a range of programs and services to children from 2 through age 5.

A toddler separation class is offered for 2 hours daily. This group is intended to be a first school experience and is designed to promote language, cognitive skills, and positive social emotional development.

Children between the ages of three and five attend preschool classes. Preschoolers with special needs receive special education and therapy services as authorized by their school districts. The New York State Department of Education regulates the preschool program.


Typically developing children attend preschool classes through parent paid tuition. Building Blocks Developmental Preschool is also licensed by the New York Office of Children and Family Services as a Child Care Center. This means that our program must follow specific regulations in order to maintain this license.

In 1994, Building Blocks began offering integrated classes which enroll both children with and without special needs. Four year old children from Commack School District’s Universal Pre-Kindergarten (UPK) program began attending these integrated classes in the 2000/01 school year.

Building Blocks' programs for children with special needs are funded by Suffolk County and New York State. Parents of typically developing children pay tuition. Children from Commack School District, who are enrolled as Universal Pre-kindergarten students (UPK) have their tuition paid for by Commack Union Free School District.

Presently Building Blocks has a staff of over 150 teachers, therapists and paraprofessionals. Our staff includes registered nurses as well as psychologists, speech and language pathologists, occupational therapists, physical therapists and a social worker. All staff are fingerprinted and cleared through the New York Child Abuse registry and Justice Center.


Parents are encouraged to be active participants in all of Building Blocks' programs. Parent support groups and parent workshops are available on a regular basis. Participation in classroom activities is encouraged and parents are invited to special events. 

Building Blocks parents and staff work together to ensure that the children receive high quality education and services that support growth and development.
