Whether your child is enrolled in school or homeschooled, you may want to better understand his scores on group achievement tests. If he is in school, knowing where he is performing as compared to both grade peers and children in older grades can help you advocate for appropriate educational placement. As a homeschooling parent, it can help you better plan your curriculum.
We have links to charts that show percentiles for various groups on tests such as SAT, ACT, and EXPLORE for Talent Search, NWEA MAPS, and more. I will continue to add to this list as other charts come to my attention. As always, please let me know if you know of useful data that I do not have here.
NWEA MAPS tests
A RIT score at or above the 95th percentile is the point at which most public school systems will consider the child to be "gifted."
This long report has charts which show the percentiles for various grades in the fall, mid-year, and spring. It includes math, science, language arts, and reading percentiles.
This chart shows the newly released 2011 RIT Scale Norms. Expect to see some difference in the percentiles obtained on MAP testing with this new set of norms.

2010-2011 summary of SAT scores and percentiles for 7th grade TIP Talent Search participants
*The Center for Bright Kids has decided not to publicly post the 2011 Western Academic Talent Search (WATS) Interpretive Guide. While I do have a copy of the guide myself, I must honor their decision to only share it with participants of WATS.

This is the most complete chart I've seen for converting your child's EXPLORE, SAT, or ACT scores to a percentile as compared to grade peers who participated in NUMATS within the course of the past three years.
