Cornerstone Day School

Cornerstone Day School is a special education school serving grades 5–12 in Cranford, NJ, designed specifically for students with learning differences, ADD/ADHD, and non-behavioral emotional challenges. With small class sizes averaging 8 students and a therapeutic approach, the school provides clinically certified programming to help students build academic and social-emotional skills in a structured, supportive environment.

The school's clinical model is grounded in a clear progression: students work toward returning to their home district or mainstream private school when ready, transitioning to a less intensive setting, or—for high school students—preparing for post-secondary success in work or college. Faculty are highly qualified, with 60% holding advanced degrees. The school is licensed by the New Jersey Department of Health and Human Services as an outpatient mental health center, ensuring clinical oversight alongside academic instruction.

Tuition is covered by school district referrals, making the school accessible through your child's IEP or 504 process. Rolling admissions are available year-round. The school also offers summer programming and extracurricular activities including sports and recreational options to support whole-child development.
