What percentage of kids in FCPS score 99.9% which is a score of 150 to 160? Will it be different this year considering these 2nd graders were online the whole of 1st grade and half of kindergarten?

Less than 1 or 0.5 percent of FCPS kids population who take cogat in 2nd grade.

Do we have any idea if these are national percentiles or just FCPS? Also, just for this year's test or inclusive of multiple years over time? I'd assume that this year's scores will be lower after almost 18 months of distance learning...

These are national numbers, it's just the way that the quartiles break out. But it's not correct. A 132 is 98th percentile (that's why that's the usual cutoff) and a 136 is 99th percentile.

Could you share the link that has the rest of the percentages? My child is below that 90% level (not expected to be in AAP, I'm just curious).

CogAT score is based on the normal distribution with the mean of 100 and the standard deviation of 16, same as IQ. You can go to the following link, and read the columns “IQ” and “16 SD Percentile”

Yes it did for those who took it in April 2021. Something was off about this past spring's NNAT. It wasn't normed correctly.

^ WISC and most other IQ tests use a standard deviation of 15. CogAT and NnAT use a standard deviation of 16.

That makes a difference definitely, but this year's NNAT was abnormal as compared to previous year NNATs. You can almost track on this board what NNAT/COGATs were for several years and the scores of this Spring's NNAT are off kilter.

Cogat scores of this year can also be great. Kids are getting smarter.

In general, the NNAT is not a well-normed test. There are too many extreme scores at both ends of the spectrum. A somewhat dated but interesting article about this here:

After a solid year and a half of distance learning? I doubt that very much.

Except Cogat is on a scale of 160 and IQ appears to go higher. Anyway, it's simple enough to know that 100 is 50% is average. So if you're at or around 100, your kid is solidly average. If above 100, your kid is above average. If below 100, your kid is below average.

We don't have ours either, which means it likely wasn't sent on Wednesday.

It's snail mail. The FCPS mail goes to the central office and sent from there, versus the local post office. It's so irritating the schools wont share scores when we are asking for it.
