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.

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

OK.
Grab a pencil and paper.
Ready?

School A has scores 1,2,3,4,5.

School B has scores 2,3,4,5,6.

A score of 5 is 70%ile across the district A+B ,
80%ile at school A, and 60%ile at school B.

A score of 6 is 90%ile across the district, 80%ile at school B, and 100%ile at school A.

Now see if you can construct your own example that demonstrates the same phenomenon.

You still don't understand what a percentile means. To score in the 99th percentile means a kid had to score higher than 99% of other kids taking the test. If they scored in your mythical 100th percentile, that means they scored higher than 100% of the other kids taking the test -- which means they had to score HIGHER THAN THEIR OWN SCORE. No matter what school they attend, no matter what schools you compare, no matter what boundaries you use to calculate, that is simply impossible.

NP. Yeah I don’t know what this argument is about but there is no such thing as 100% percentile. It’s just not a thing mathematically. Why don’t you just say 99.9 percentile if that’s what you mean, PP.

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.

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

Im not saying this is some contest, as disadvantaged kids are disadvantaged, period. However if you look at the numbers in, say, Baltimore City, and compare them to MCPS, MCPS comes out far ahead in scores. Moreover, MCPS has large clusters of overachievers. For example just look at NMSF lists if you want an indicator of 99th percentile. They are disproportionately clustered in MCPS and HCPS for the state. And MD top percentile scores are usually higher in MD than other states. This is driven mostly by MCPS and HCPS.

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.

ok, again: what do you mean by "far represented". how many percent of MCPS students is at the 99th MAP percentile? how many of those in the W cluster?

This isn't data MCPS has ever released, but there was a report several years ago showing the number of "highly able" learners per middle school cluster, I think.
