My kids are still too young for testing like that. But I have two friends who's kids had to take LEAP tests in the 3rd grade last year. All the teachers did was push the kids to teach them what was on the test, not what was part of the curriculum. The school board, principles, and teachers alike we focused on one thing and one thing only, making those kids pass so they could look like they did a great job. Both my friends' kids struggle now, it seems they misssed out on some skills they should have learned while taking a million practice leap tests. This stressed the kids out, the parents out, and the teachers. Of course if the child failed they are held back a year. But these tests are suppose to be indicators of where the kids are, the teachers shouldn't be wasting valuable class time trying make sure the kids pass. Its a test for a reason, to assess the child's capablities.
As a matter of fact, last year during testing, a principle at a local elementary school was walking around monitoring the kids testing. She whispered to a student "You might want to recheck that answer". She was immediately fired.
