You may have to have a copy of whatever it is that states you are entitled to a copy of them, and to explanations, etc...
The Wrightslaw site should have the actual rule.
6 weeks or so AFTER you agree on an IEP you should go to school and ask for a copy of the IEP and his file. After EVERY IEP change you should do this.
When my son ended up in the psychiatric hospital I was asked to get a copy of his IEP and bring it to the hospital. The Special Education teacher never DREAMED I would actually open the envelope and read through the stack of papers. She had no clue how boring the waiting room was or how long I had to wait because the therapist was handling a major crisis.
Sp Ed teacher had CHANGED THE IEP and forged both my initials and my signature!!!
You can imagine her surprise when she was called to the Board of Ed building immediately on the first day school was in session after I got these records. She tried, for quite a while, to make it seem like I had broken rules by reading these records.
THen she tried to make it out that I didn't understand these records. By that time even her principal was looking embarrassed. She totally changed the IEP to allow our son access to things he didn't need access to. Like the internet. She had ignored the way he hacked through the netnanny software to go to forbidden sites.
So be very sure to back up and check the IEP after a few weeks. Also check his other records, esp if he suddenly seems to be in trouble a lot. You just never know what is in the records until you check up on them.
Hopefully you will never find a reason to need the double check on the IEP, or even a reason to justify the school giving you a copy of his records.
