[quote=Anonymous][quote=Anonymous]We have now devolved into deluding ourselves into believing that Fairfax County possesses the brightest top 20% of the entire country. This board has become nutso. Do some of you even understand what you are saying?[/quote]
Yes, we understand what we're saying, but clearly you don't.  Iready is not an intelligence or aptitude test.  It's an achievement test.  The 5th grade test is normed using a regular group of 5th grade kids.  It is not being normed with 5th graders who are taking algebra or higher in Chinese school or AoPS.  [b]There will be way more kids than mathematically expected scoring in the 99th percentile or far above it, since there are a lot of kids who are hyperaccelerated outside of school[/b].  It's akin to the NNAT, which is normed using unprepped kids, and which has entirely too many kids scoring in the 99th percentile due to prepping.  To answer your earlier question, the 99th percentile is not truly the 99th percentile.  It's just the 99th percentile of the norming group and is not especially representative of the affluent, motivated areas with so many kids in math enrichment/acceleration.

The math questions at the higher end are not tricky problem solving type questions that would show special intelligence or aptitude.  They're problems that either the kid has been exposed to and understands, or ones where the kid has no clue what they're talking about. It doesn't take special insight for a mid elementary aged kid to understand a box plot, for example.  They just need to have seen it before and know what it is.  A 5th grader taking Algebra in outside enrichment with a score exactly 30 points above the 99th percentile would be in the 98th percentile for 7th graders and the 75th for 8th graders.  This does not at all seem unreasonable to me, since it would be more closely comparing the kid to other kids in the same math level and with the same math exposure.  [/quote]
