[quote=Anonymous][quote=Anonymous][quote=Anonymous]I think it’s teally good that we were given the MCPS percentiles in addition to the national percentiles. It really paints the picture for me. I have twins. One scored in the 99th percentile nationally on a particular section of the CogAT, but only in the 93rd percentile for MCPS. The other scored in the 98th percentile nationally on that section, but only in the 85th percentile in MCPS. Another poster that their child scored in the 97th percentile nationally on that section, but in the 83rd percentile in MCPS. That tellls me that among the fifth graders in MCPS who took the CogAT this year, roughly 7-8% were in the 99th percentile nationally for that test section and another 7-8% were in the 98th% nationally. Two kids could both be in the 99th% on a MAP test but have scores that are 20 points apart. If 3% or less of MCPS fifth graders get accepted into the competitive magnets, then they can’t take all the students who have always been in the 99th% nationally on all tests because there aren’t that many seats in the program. The selection committee had to try to determine what separated one 99th% from another. In the end, I’m sure there was a certain amount of luck involved because they were probably looking at very small differences in lots of cases. When you add in the consideration for home middle school cohort, well, it’s easy to see why many parents can’t understand why their very high performing child didn’t get in and it seems unfair to parents because the home cohort aspect is something they couldn’t control for and cannot understand because they don’t get to see the grades and test scores of other students. How do you ever really know how your child compares to other students if even the 99% kids aren’t all the same?[/quote]

99th percentile kid here.  Grade, age, national and MCPS scores all the same.  V-99%, Q- 99%, NV- 98%.  What was interesting was that 51/52 scored 99% for Quantitative, but 43/60 for non-verbal scored 98%.  That struck me as odd.  I'd be curious to see what the percentile ranges were for each ability.[/quote]

To complicate things a bit further, mcps used the age-normed scores, rather than the grade-normed ones, so the number correct to percentile conversion may not be consistent for different students.  My young-for-grade student got 99% mcps verbal (57/60), 87%Q (35 correct out of 36 attempted out of 52 total), and 93%NV (39/60).[/quote]
