County Reports

Important Notes:

Counties are included if at least two school districts participated at any grade level.
In most cases, the usage rates do not represent every school in the county, but just the students at the participating schools, and only those students who filled out a survey. Pay particular attention to the introduction to determine how representative the report is.
To see a listing of schools that participated in 2008-2018, visit our school participation page.
