Click on the state-by-state info and read what it says about your state. This is for taping in general and really addresses whether or not COVERT taping is allowed. What you want to do is OVERTLY tape the meeting. Typically, you need to give the IEP Team a certain numbers of days notice, in writing, that you plan on taping. This is so that they can bring their own recorder. They have to let you tape if you give them a good reason (like your husband can't attend or that you cannot fully participate and take notes at the same time). If THEY tape the meeting, they MUST maintain that tape as a part of your child's permanent file (or at least a transcript of it). You can then ask for a copy of that transcript as part of a records request. You can make sure the transcript says what your tape says. I tape ALL meeting so that they don't get all fired up when I decide to tape. Since I do it EVERY time, it's not a signal of trouble to them. Then, when there is trouble, people don't realize that's why I'm taping and they usually continue to ignore the tape and I get what I want. I actually never have had a tape transcribed and I have never re-listened to one, but I like it as part of my Rule of Adverse Assumptions strategy.
Here is a great article on taping, including the rules in various states:

Here's the new url. Is that what it's called? I am considering taping if I can come up with a recorder in time.
I can't tell if it is legal or not.
