Thank you for the link aculady! I'll take a look through it today
DS does have a current neuropscych eval as well as a current IEP with accommodations, so he's heavily documented lol. Ironically he was in a small group testing situation at school when the bubble sheet test happened - but he was the only student who had an accommodation to write answers in his test booklet, and the proctor simply forgot to not hand him a bubble sheet when she was passing out the test. When she realized that she'd accidentally given it to him, he'd already started to use it, so she decided he must not really need the accommodation and didn't say anything to him. The school actually tried to use this as an argument to remove the accommodation from his IEP, until we pointed out what had happened with his test scores when he used it!
