No, the CogAT 98% National was 92-95% of the selected MCPS students who took the test, who had already been screened before being invited to test. You're not comparing the same types of pools. |
This is the key detail that people are missing and explains why one kid with 248 gets in while others with 270 and 280+ don't. They determined who they believed were good candidates and put them in a pool. They did not want to split hairs and just picked randomly from the pool. This is exactly what they said they would do this year. It isn't complicated. |
Did they use the home school cohort only for CES or was it also used for MS selective magnets? |
No one knows for sure but if I had to wager, I'd guess each home MS was allotted a number of seats that were filled by a random pool draw. |
Regardless, it aligns with the data that MCPS published showing that their mean was a few points higher than the national percentile. |
Everyone can debate about it but its pretty pointless as MCPS will do what they want. My kid got 250's and his middle school was surprised he wasn't even in pool for one school and waitlisted another. There is no rhyme or reason but thankfully they provide higher level math. You really need to look at the programs. We were waitlisted for Eastern but it really only gave one additional class but that meant my child couldn't do an elective they wanted which was really disappointing if they choose a foreign language. So, while you get a similar cohort, you also lose electives, like foreign language or arts.
MCPS should provide regular and real honors classes at each MS and HS for the rest of our kids. But, they don't so not much you can do. |
That's the nature of random pool draw. Once in the pool for your home MS cohort it had nothing to do with your kid's scores. The data provided on this thread supports this. |

This makes sense. Also would help equalize across county for schools where tutoring is widespread. |
Also 280 and 248 are both 99%. In the past I've read some claim they only looked at the percentage and not the score. That could also be a key detail. |
Except there isn't much of a cohort at our MS. Maybe a dozen kids. |
We have always supplemented. Nothing wrong with getting tutors given how poor MCPS curriculum has been. |
That universal review included about 6k students, so more than half. |
It doesn't show SES. Why and how would they know your income???! |
There seem to be a couple of misconceptions here. For the past few years, when kids have taken the CogAT for CES and MS magnet admissions, MCPS has reported the raw score as well as two different percentiles - the national percentile and the "MCPS percentile." The MCPS percentiles showed how your child's scores compared to the scores of kids attending MCPS schools with similar SES profiles (not kids whose families have similar SES profiles to yours). They don't specifically tell you which SES band your school is in, and no one knows exactly how the schools are grouped. The best guess I heard is that the three groups are Title I, Focus, and everyone else. The MCPS percentile is the one used for admission to ES and MS selective programs. This process did not happen this year because CogAT was not administered. The MCPS percentile has never been calculated for MAP tests, although the MAP report will show both the national and district averages for your child's grade level. |
