Just to clarify my previous post:
As some of the other girls have said, it's not going to be a 'schooling' test - it will be assessments for cognitive ability, and there will be follow up assessments because of the way these results change in this age range. If they don't talk about monitoring it like this then ask the questions of them. These are not really predictive tests, just tests to see where children are at at the time of testing and indicative of what they need, if anything, to 'catch' up to a certain range.
The test can be suggested and recommended by the teachers, but they are conducted by people competent and qualified to do the testing (not like the stupid MCHN 'development' tests that are conducted like a game of monopoly...unless that was just MY nurse, grrrr!!) - they are not done by the teachers. It's then up to you to take the results and discussions back to the teacher or the school to see how you can best serve your daughter's educational needs.
It's not a reflection on you, it's just about giving your daughter a fair start
