How to word my response to principal?

I have an 8 yr old son who has mild Cerebral Palsy due to brain bleeds at birth. Last year he was also diagnosed with ADHD. After he brought home his most recent progress report and was failing 3 out of 6 classes with grades in the 50's, I wrote a formal request to have him evaluated for services. He currently recieves no services and is not classified as special ed or 504. Each week my son has a regular schedule of homework (Ex: Monday, write words 3 times each, Tuesday, write 8 sentences, Weds, put words in ABC order, etc). Due to his ADHD, tasks like homework and keeping track of things/turning things in a issues for him that affect are reflected in his grades. I sent the request for formal evaluation to the principal yesterday and today my son comes home and tells me that before lunch today he was told by his teacher that he was not allowed to go to recess after lunch and instead was to go to study hall to do the rest of the weeks homework in advance. My opinion is that he is being punished because I requested that they evaluate him and that the are having him do this so that they can make sure that his work is all done completely to improve his grades so that they can later justify not providing testing. He was the only student singled out today to go to study hall and work on homework that wasn't even due yet. In addition, as a child with ADHD, he needs that energy outlet that recess provides.
It was suggested to me that I email the teacher and find out what happened while playing somewhat dumb. I was told I should ask if this is a new technique they are using with students, and if so, what are the criteria to determine who participates and who doesn’t. Also ask if this will be a daily/weekly activity, and if not, when will it happen. The logic behind this recommendation was that there are really no good answers the teacher could give for her behavior and document what she had done.

Wondering what all of you think?

I will agree with the one responder about proceeding thru the chain of command about your concern.

In the description of your issue there are several procedural issues that are of concern to me. One, you have raised the request for an evaluation. This is a procedural duty of the school division to act upon this "referral". There are regulatory timelines that govern this and are found in your state regulations that govern special education. This could be a serious oversight by the school if they take no action. In effect, your procedural rights have or will be violated. Second, to the extent you continue to have a concern about your child and his potential need for special education intervention, you may either focus your concern on the IDEA process or within the Section 504 process to achieve reasonable accommodations if he is eligible. Either way, I suggest you place your request in writing to the Director/Supervisor of Special Education.

I will check your progress by viewing your postings on this service. Good luck. By the way, what state do you reside?
