We recommend p[ersonally visiting the school, talking with personel, and gathering information directly. This way you will be able to arrive at a clear understanding based on your direct personal impression as opposed to one based on the value system of others.
We also have children attending the school so can answer personally and professionally.
It is unlikely that you will get much response here. The rating are still so seldom. In the mean time you might try contacting some parents in the area and get their impressions. It won't be easy but maybe you will be willing to undertake the task of calling around the school and finding some parents. Good Luck!!
