if additional testing is in the offing, you have to tell them that you had testing, and what the instruments were, or you will end up putting your child through a slate of useless, invalid testing. (The re-test time for the same cognitive instrument is actually 24 months.) ... they have to select different instruments...
I agree with the ethics of the situation, and parents ought to share which test(s) their child has been exposed to. Some may find it easy for things like this to (willfully) slip through the cracks. Overexposure to tests, and validity of test results, are serious concerns with far-reaching impacts on many people.
Prior to test administration, are parents required to sign a form attesting that their child has not been exposed to the specific test instrument(s) within a 2-year period?
Sadly, unless/until there is enforcement such as laws under which parents will be penalized for falsification of records related to withholding prior test information (resulting in their child re-taking a test within the 2-year wait interval), some parents may find this an expedient way to game the system in order to achieve a higher IQ score.
