Looking at the class sizes for algebra 1 in 7th grade, it appears to be more than 10% of FCPS kids who actually end up taking it. So it looks like the schools don't strictly follow the criteria.

Well, from what you're saying, if it's a percentile based on National average, then it should be 9% of the entire nation that become eligible based on the IAAT. This means the 9% is spread across many school districts in the nation and FCPS should have an even smaller piece of the 9% pie (not more).

What?!?

I am the PP to whom you are replying.

I will give the stat for the CogAt, when my children took them. In the past, FCPS tried to set the CogAt cutoff at 10% of the FAIRFAX population. The years my children took them, the cut off was a 131 and a 133. NATIONALLY, the 131 and 133 in those years, was at the 98th percentile. So, [b]10% of FAIRFAX students scored in the top [/b]2% in the NATION.

If we extrapolate from that, it is not difficult to believe that 15-20% of FAIRFAX students would score in the top 9%[b] in the NATION for Algebra readiness.

I must have misses a bold icon. Sorry, my typing skills stink.

Why does it matter?

I meant...for the 96%tile?

Any way to find out what the actual top scores were for the kids that scored in the 91%tile?

The number taking Algebra in the 7th grade is probably around 15-18%: 2000-2500 kids out of 13000. Not all of these kids are in AAP, though.

Umm, percentile rank is not the same as percentage. If a student scores above 91%, it doesn't necessarily mean they are in the 91 percentile rank Just to simplify things, if 100 total students took the test and the first nine students had scores like "100%, 99.7%, 98.4%, 98.2%, 97.6%, 97.3%, 96.5%, 96.1% and 95.9%" only those students will be at or above 91 percentile. A student who scores 95% will not make it in the 91 percentile or above rank, even though thee score is great. Got it? Most people confuse percentile with percentage.

PP: and remember, this is the top 15%-20% of FCPS taking the test, so one would expect higher scores.

With that said, the test is designed to test readiness for algebra, and is typically given to 7th or 8th graders.

Everything related to AAP -- including prepping Kindergarten students for the NNAT -- is based on getting kids into TJ.

Not true. Some of us just want our gifted kids to learn something in school. We have no TJ plans.

True, just remember "the clock is ticking and we're keeping score."
