Ya know - when a local private school converted to Charter, they had to operate via new rules. State was paying so tuition was now free. But it required enrollment by a certain deadline. I literally saw children whose feet barely touched the ground as their parents (fueled by the school's prior academic prowess and dreams of miracles) were dragging them out of the car and sprinting to the school door to sign up.
Seriously (although the above is true)
Some prospective private school parents don't know how much they may be hurting their student's chances by being so overt and so controlling. That's why, when some disappointed parents speculate that a less qualified student took their child's spot, I suspect it had more to do with a equally qualified, less coached, more communicative, more enjoyable (fill in the blanks) student took it. And that the newly admitted student's parents were deemed to be likely to generate 90% less drama and complaint calls to the school afterwards
