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  [/quote]

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?'[/quote]

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.[/quote]

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. [/quote]

300+ in 8th is 95+% (probably 97+%ile) in W, but 99+%[b]  (often 100%ile) [/b]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.[/quote]

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

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[/quote]

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.[/quote]
