Cornerstone effectively combines academics and clinical supports and interventions to assist the students in developing academically and emotionally. The academics are tailored to each students current abilities AND current mental status (i.e. current emotional state. ) When a child is in a therapeutic school, both of these need to be considered together if the child is to make progress academically and emotionally. The school strongly encourages and supports family involvement , including weekly family sessions, and rightly considers this involvement to be an integral part of the child's programming. As a family, we have been very pleased with the school and our child's progress.

Reading the other reviews of Cornerstone makes me feel I should remind readers to keep in mind why you and your child need for them to attend a school like this, and compare that to what they experience in the alternatives. When taken in that context, it is easy to appreciate the integrated approach provided by Cornerstone. Yes, there are distinct threads that need to be addressed (medical, psychological, educational, administrative) and those threads are handled by different people within this structure. You shouldn't expect to be 100% hands off because of that. If your child were outside this environment, you'd be coordinating all of those things, so it won't kill you to pay attention and have a hand in the process here. Regarding academics, this is a place where they can be challenged if they are psychologically able to handle it, so the first step is getting them to that state, and this can take some time. Your child didn't likely end up with their issues overnight, so don't expect them to be solved overnight, nor on their own.

Cornerstone Day School is like no other. Not only do they take care of the students but also take care of the families. Family counseling is provided as part of your child's curriculum which might seem to the average person overkill but it is very important to help your child. The counselling staff are wonderful. The academics are great and the administration in conjunction with your school district work very hard to accommodate each child's academic needs. If you have a child with any emotional or psychiatric conditions they would be lucky to be enrolled in this school.

The academics are poor. The teachers are uneducated and most of the class time is wasted talking about irrelevant subject matter. If you want your son or daughter to have a future, as in attending college, there are other schools that will better prepare them for the world. Cornerstone does not heal the student in a holistic way. There narrow use of psychoanalytic therapy demands that a student feels 'sick' instead of motivated or confident. Overall, the school is underfunded and poorly directed.

Posted October 7, 2011

Cornerstone Day School should be considered a very short term placement for many reasons. The education provided there (text books, intervention, teacher effectiveness) is poor and without parental involvement on a regular basis (outside 5 min meetings a few times a year). Educational policies, accommodations, and adherence to IEP's is inconsistent. The quality of psychiatric and psychological care there is HMO like in quality and access and when care is accessed, it is disconnected to the educational process even though it's under one roof. The directors are better at "marketing" the school rather than running it. Only kids with less severe emotional issues and those with little educational needs who are bright and self-directed may benefit here for a very short period.

About these ratings

The Community Rating is the school’s average rating from its community members (e.g., parents, students, and school staff). The highest possible rating is five stars; the lowest is one star.

We currently do not have any test score information for this school. Unlike public schools, private schools are not always required to report data about their schools or not required to take the same tests as public schools. Many private schools take different standardized tests; however, that information is often made available only to families of enrolled students. We strive to acquire additional private school data whenever available.

What is the GreatSchools Rating?

The GreatSchools rating is a simple tool for parents to compare schools based on test scores, student academic growth, and college readiness. It compares schools across the state, where the highest rated schools in the state are designated as “Above Average” and the lowest “Below Average.” It is designed to be a starting point to help parents make baseline comparisons. We always advise parents to visit the school and consider other information on school performance and programs, as well as consider their child's and family's needs as part of the school selection process.
