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.

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”

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.
