What if the Louisiana state government in Baton Rouge declared that you and every person in the state must take the same medical test which would require a week of your time away from work plus a lot of lost days for preparation before the test? Further, suppose that the test results would be of no use to you individually to diagnose any medical problem and that all test results would be available for interpretation only by politicians and their supporters.
Test results would be used for political purposes supported by large campaign donors.
Would you willingly take this test? Certainly NOT!
OK, now think about whether you should opt your kids out of PARCC.
