Both of our daughters thrived in this school. It is a safe and responsive environment, and because it's a Montessori model, it allowed our bright girls to excel and become independent learners. Our older daughter had struggled in a traditional classroom because she was easily distracted but this model was a perfect fit for her.
Our younger daughter was thriving and reaching beyond her potential from the first days in the school at 3, which led us to transfer our older daughter into the school. Both are doing great and more than meeting academic standards, while also maintaining their love of learning. Check out what it costs to send your child to a private Montessori school and then do the smart thing and send them to #53. They'll have a more diverse set of classmates, too! (The only reason this review isn't 5 star is really beyond the control of the school. The Common Core curriculum has been forced on the teachers and it pushes out some of the Montessori model, especially in the upper grades. But it is a good transition into the high schools, which can't offer Montessori.)
Don't be put off by the low rating given by this website. This academic year, 2012-2013, Montessori Academy took over the designation for a failing that was closed to enable it to receive school improvement grant money to expand their successful school. We were willing to do this because we have no doubt we can turnover the test scores from the previous school.
