2008 Saint Louis County MAP Score Summary by District

For some reason every source makes it very difficult to retrieve MAP score data for easy comparison between districts. Why is that? So here is my chart with 2008 numbers straight from the Post-Dispatch online. Here you can click any column to sort by that column.

The numbers listed are the percentage of students who were proficient or advanced in each grade level (3 to 11) in each subject (C = communications arts, M = mathematics). ET is the total for all precentages for elementary grades (3 to 5), MT is the total for all percentages for middle school grades (6 to 8), and ST is the total for all percentages for senior high grades 10 and 11. CT adds all the grades together but triples the weight for the senior high percentages since there are only two of them.

One interesting thing I noticed is that hardly any districts are near "average", most are either considerably above average or considerably below average.
My Commentary on the Numbers
Note that these numbers do not necessarily show which schools are "better", in reality they show what schools are attended by top performing students. Over St. Louis County as a whole, about 40% to 50% of the students test at a "proficient" level or higher. However, within districts this percentage varies significantly. In some districts 60% to over 70% of students tests as proficient or better, yet in other districts less than 1 out of 4 students tests at the same level. What this truly shows, therefore, is what school districts attract top students, and these tend to be the more affluent districts one would expect (Clayton, Ladue, Brentwood, Kirkwood, Rockwood, Lindbergh, Parkway, Webster etc.) Good students want to go to school with other good students, so they all gravitate to the same top districts. The demand for housing in that area drives up real estate prices in those districts which then creates more tax dollars for the schools. That elevated population of good students plus the increased tax revenue then allows those more desirable districts to offer more advanced classes and programs that could never be filled in districts with a lower proportion of good students. So it is a viscious cycle, the good schools attract all the good students which only make their test scores (and housing prices) higher, and the other districts cannot compete.
