DISD is an urban school district with 9 schools. The first day of school is August 13. Denison High School's predecessor, the Educational Institute built in 1873, was the first free, graded school in Texas. The calendar sets aside 2 additional days (February 12–March 26) that may be used as weather makeup days if needed. This calendar includes 2 professional development days, 8 early-release or half days — useful to know when planning childcare.
