I can't say enough good things about PLA. My son went through 3 other daycares before joining PLA. The positive impacts PLA has on him are immediate and very visible. He learns so much and loves going to school every day. He even complained when he didn't have homework :) (hope that continues).
My only regret was not finding PLA sooner. My son will start kindergarten in a couple of months and I have no concerns now about his readiness because of PLA.
