Yes, my children attend public schools - fortunately very good ones. But they are all the same in that respect. You have to be willing to keep shovel in hand to dig info out. Info that should clearly be available to you.
So, your kids attend "good" ones, whatever that means in this era of dumbed-down standardized tests.
Read the stoy again. This mother did not know BEFOREHAND what the school was going to do, and AFTERWARDS has to deal with the consequences.
You can dig all you want for the info, but when you only get it after the fact you are in fact powerless to protect your children.
Anyone who has kids in public school is asking for problems.
