There is no literature out there that gives a correlation between the two tests. Either it hasn’t been studied or there isn’t a strong correlation at all. The makers of MAP do not comment on a correlation.

This. They measure two completely different things (aptitude and achievement) but obviously bright kids with a high Cogat often tend to be high achievers with high MAP scores. But, no, you can't assume your child who does well on the MAP would also do well on Cogat or that your child with a high Cogat will have a high MAP. MCPS this year was looking for kids with high aptitude and high achievement and high effort (grades are a decent proxy in elementary) for admission to the CES

Thanks! I was looking at this because the test for admissions into high school magnet changed to Cogat this year, and I was wondering if there was a way to gauge. All of this conversation was helpful.

Mmm... not necessarily. My un-prepped child does well but not amazingly well on the MAP tests. But he was 99% COGAT. If you are teaching your child outside the school curriculum, they may achieve much higher on MAP than COGAT, especially in math.

Mine had a big discrepancy in MAP-M. She’d always done OK (95-99th percentiles) on the MAP tests. She’d been exposed to a lot of the concepts, and it helped that it wasn’t timed, I think. But in testing for both HGC in 3rd and middle school magnet in 5th, she scored lower on the math sections (mid- high 80s, I think?). Her grades in compacted math have generally been As and Bs, but she definitely doesn’t love it.

Her reading and composite scores were much more comparable (high 99th percentiles on MAP-R and both verbal magnet tests, 99 composites on both magnet tests). So in math, at least, it looks in her case like the cogat did do a better job of isolating for natural ability vs. MAP’s mastery of specific concepts.

+1 I do think there is one key difference though--Cogat is timed.

Correct, and that made all the difference for my oldest, who is very slow.

This is key. Some kids go back and continue on MAP for days. They won't have that option on cogat, and it does impact scores for some kids.

My kid always got 99 on both, as did some of her friends. I haven't talked with anyone who's experienced a major discrepancy, other than kids who don't do well on timed tests.

Thanks for the terribly unhelpful response. I have read many, many posts about why can't my child get in with X score vs. Y, and does it pay to prep. That's not my question. My question is: is there a correlation between how my child does on Map-M/R and how they will do on Cogat? I can't find that question asked - and I've looked. SO if you can provide info or point me to where I can, that would be helpful vs. "go look for it."

A million threads on this. Read them and take notes.

If my child has been reliably in the 99% for Map-M/R for many years, do I need to worry about their performance on Cogat? Shouldn't they perform just fine on the Cogat without much, if any, test prep?
