Depending on how far down the road their start date was they may not have finished interviewing. Parents are busy with their lives just as providers are and not everyone sets aside a couple weeks to do an interview every evening and a few on the weekends. Not hearing back till 2-3 months before the start date can actually be perfectly normal. Parents are afraid to make the wrong choice and always keep hoping for something else to be out there. When they reach a certain point they look at everything they saw and pick one.
