The Preschool Integrated program is located at South Mountain School.  Three-year-old students attend class in the mornings; four-year-old students attend class in the afternoons.  The ratio of regular education students to special needs students is approximately 50-50, with the scales more often leaning toward the regular education population.  This integrated program (inclusionary) follows a general education preschool curriculum. All of the preschool integrated teachers are additionally Teacher of the Handicapped Certified. The special needs students receive in-class support through their teacher, and related services are provided in accordance with their IEPs.  Each preschool integrated class is additionally staffed by a paraprofessional.  Behaviorist support is provided on an as-needed basis. 

Special needs students are automatically admitted to the program upon determination of eligibility for special education and related services.  Regular education students are admitted through a yearly lottery process.  There is a tuition fee for regular education students. It is the philosophy of the Millburn Preschool Program to foster developmentally appropriate programs for its students and to encourage them to become independent, confident learners.
