This is a very serious question, and I think the answer lies in 2 different parts.

1. What is there to gain (or lose) by testing? If it will make a difference in the services available to your little one, it might be worth your while.

2. How fair is the test? If the test can be administered in a fair manner, then it might be worth considering.

Our local school district wanted to test Calvin a few years ago, and we almost shouted NO! in unison.

First of all, their assessment of his abilities was the lowest of everyone he worked &/or played with.

Secondly, there was nothing to gain by testing – it didn't matter if he did really well, since they had already proven they couldn't teach him. But if he did not score well, they would have the option of moving him into a lower-functioning class where he wouldn't need to be "taught".

Thirdly, they couldn't administer a fair test. They agreed that he had (has) apraxia and is non-verbal, yet they weren't willing to make accommodations for the test. Everyone else who worked with Calvin (ABA, Speech, OT, PT, NMT, and friends and family) would attest that he knew everything that was being spoken to him. He just needed to communicate via alternative communication methods, such as PECS (Picture Exchange Communication System), word cards, or Facilitated Touch.

This is one of those questions that doesn't have a right or wrong answer, per se. Just think about who wants the test, and why, and remember that the results will become part of your little one's permanent record...
