Welcome to Cornerstone Day School

Cornerstone is a private therapeutic school for students in grades 5-12 with major emotional and psychiatric problems. Since its founding in 2006, Cornerstone has changed the nature of special education for such students in New Jersey, building a reputation for clinical and academic achievement. Our students must be in a school setting that can accommodate their unique needs with small classes, specially trained teachers, and individualized clinical services. Students with a primary diagnosis of oppositional defiant disorder, an active alcohol/drug abuse diagnosis or who are dangerous to others in any way, are not appropriate for Cornerstone

Finding the appropriate placement for a child with emotional or psychiatric problems can be a confusing and difficult task. We are pleased that you are considering Cornerstone Day School, and we hope our site will provide helpful information and increase your understanding of, and interest in, our school.
