Revisions in Results and Population

There were changes in the number of Michigan school districts this year as White Pine, which had a minimal number of students, was dissolved into Ontonagon Public Schools.

Detroit Public Schools responded to this year's survey and its results were updated for last year. This increased the 2008 survey's population size by one.

We also found that Grand Ledge Public Schools uses a transportation contractor. The results for last year have been corrected.
