Within each conference, the UIL separates the schools in regions, and then further separates the regions into districts for various contests. The districts are numbered from 1 (in far west Texas) to 32 (in south Texas). There are always 32 districts in Conference 6A and Conference 5A, but the smaller conferences may have numbers skipped based on the number of schools in the conference. No more than 10 schools are permitted in a single district unless all schools and the UIL consent otherwise; the preference is for an even number of schools in each district (6, 8, 10) though in some cases travel issues may prevent such.
