I also just want to talk about this and I felt that it was not a topic that would go down well in the pick up line
Oooooohhhh.... how I can identify with that!
And how did he learn two years of math in three months?
It could be any # of things, including just having a great test day vs a so-so test day last time. Both of my 2e kids have been relatively slow to make that leap that suddenly happens when math facts become automatic - my youngest still hasn't arrived there, but for my ds when it happened it was kinda overnight - all of a sudden, he was quicker at math - so something like that can happen quickly. Is the MAP test timed? Does your ds have accommodations? Could it be he's somehow faster now with handwriting? Another thing that happened with my ds was an increase in working memory scores between 2nd and 5th grade - I don't know why... but I think our neuropsych says working memory sometimes does increase as kids mature.
Should you test again? I think one compelling reason to test would be to nail down whether or not your ds has dyslexia - that would be really important to me - he's at the point in school where the emphasis shifts from learning to read to reading to learn, and the demands on reading skills and fluency are just going to keep increasing as he moves up. Re testing just to see what's up with the recent test score increase or IQ in general, I don't think that's necessary and you might want to consider when you'll need testing for middle school and how recent it needs to be. In addition to whatever you'll need for your local middle school, if you're going to have your ds take any high-stakes testing early (SAT etc) and want to apply for accommodations, you'll need testing/diagnosis within a certain time frame (I think it's three years).
It sounds like you have good options re school!

ps - ColinsMum mentioned that an IQ test won't tell you if your ds has dyslexia, and she's right about that - but when used as a part of a spectrum of tests, such as a neuropsychologist does, it can be helpful in diagnosing or ruling out dyslexia. My youngest dd just went through dyslexia screening and IQ vs ability was part of her eval. In her case, she appeared to have struggles commonly seen in dyslexic children, but the real issue was a large discrepancy in associative memory vs her other abilities - which showed up clearly in her IQ subtest scores. Knowing her reading challenges are not dyslexia has been really important in how we approach reading plus the type of accommodations she has at school and at home while she does her homework. Plus it's made it a little easier to parent her to - but that's a whole other post! In summary, we thought she had a reading challenge, but it was something else entirely, and that's where having the IQ testing helped
