No. Private schools could just fill in the dots without reading the questions and still excell over the public school kids. They're just plain dumber than a box of rocks.
Most private and homeschools do not use state tests. How could they answer a question that has been changed to PC lingo and paganism?
Or a question like this:
Mother Earth is:
1)Our world Goddess.
2) Living in a tree.
3) The source of all love.
4)All of the above.
Of course a normal child could not answer a question like this. The correct answer "None of the above" is not there!
