You don't seem to understand the concept of uneven distribution.

You still don't get it. You can't have a lot of kids in the 99th percentile, because, again, it means the students' score is above 99% of other kids. You can give everyone an A, you can give everyone a medal for participating, but you can't give everyone a 99th percentile score.

You still don't get it.
The MAP percentiles are based on national norms. It is absolutely possible, and true, that more than 1% of kids around "here" are 99%ile nationally.

It's just like how, in a memory care facility, far more than 1% of the residents are in the 99%ile nationally for cognitive care needs.

You are correct that this is possible (I’m a DP btw) but we do not have access to any data that proves the claim you are making or makes it clear that MCPS has many more children scoring 99th than elsewhere, and people saying it repeatedly on DCUM doesn’t make it true. The only evidence we have is the median score in the district compared with nationally and they are very similar. So you can speculate or you can look at the actual data.

That can't be true! MCPS has gone downhill! How are these kids defying this?????? OMG OMG!@

They are in private after school programs, of which there are a huge amount here, or just big on Khan Academy. In addition to the big national changes, there are local Chinese afterschools, and there are several prestigious medium size national chains like RSM/AoPS that are in a few cities, but western MoCo is among them.

I have seen stats from a study showing that if you remove the low ses scores, the average scores jump. I don’t remember the exact amount but I remember being surprised.

Or perhaps I should say in particular, parents posting on dcum are probably in clusters of privileged, educated families where the kids are averaging higher.

There is a cohort of such posters here, but there are also plenty of people who don't understand basic math, and don't know about those clusters, and post embarrassing comments in their ignorance.

It only takes a small fraction of the population to be both far overrelesented in "1% of wider population" attributes, but still a statistical minority (<50%) in our dcum enclave.

Thank you for detracting that statement -- MCPS is swollen with disadvantaged children and working hard to address their issues.

It's the intersection of DCUM and MCPS. Of course all the kids are performing at an absurdly high standard! We wouldn't have it any other way. Or at least admit to any other way.

NP
it's possible, but it also depends on what do you mean by "more than 1%". do you mean 2, 3% or do you mean 25%. because people here are talking like every other child is at least 95% and a quarter or so are top 1% nationally. that doesn't seam real to me, knowing the kids (not their scores, just kids and their parents) to be the case at our W feeder. yet posters here are, yeah, my kid scored 300 in sixth grade but that's nothing because that's like everybody's score around here...

At grade level MAP 99th percentile is really easy. It is based nation wide sample. This area is known to have many high achievers

I got my DC MAP-M score from 3rd Grade (fall) of 244 to 5th Grade of 295 --- not gifted at all

I don't think you can take MAP out of grade level, but maybe I am misunderstanding. Are you talking about comparing the RIT score with RIT scores in higher grade levels?

295 is extremely high for for fifth grade. What makes you say 'not gifted?'

Yeah, 295 is way high. like unheard of high. Maybe the top 8th grade magnet students at TPMS are getting that. 250s is very high for 5th grade, 260s super high.

My DC who attends a w school feeder has a friend who got a 304. They said that six 8th graders at their school got above 300. One even got a 314. It's not as uncommon as you think.

300+ in 8th is 95+% (probably 97+%ile) in W, but 99+% (often 100%ile) almost everywhere else in MCPS.

On the 2020 national norms

Score: 300
Grade percentile

6 99.9995
7 99.996
8 99.98

But in a high performance/wealth urbanized area (town level, not county level), with competitive academic kids, and parents from "test cram" cultures, and free online trainers,
the percentiles are much farther from 100%ile for the 300 score.

When you make blatant speculative posts please identify it as such. You are guessing.

+1 it’s amazing how many pushy parents here don’t understand what a percentile is!

LOL you guys are a hoot. How can someone get a 100th percentile score? To do that they'd have to have a higher score than themselves. Even "high achievers" can't pull that off.

Keep noodling on it, and you'll eventually figure it out. If you can't, ask an 8th grader for help.

LOL go ahead and tell your kid to put on their college application that they scored in the 100th percentile. See how many colleges they get into. LOL
