Una School has 50 classrooms, a centrally-located library/media center, a recently expanded cafeteria/auditorium with outdoor courtyard, indoor gymnasium, and two outdoor playgrounds. 

Una Elementary School proudly features a staff with a wide range of talents, skills and abilities nurturing an environment promoting success for all students. When students feel safe, they learn more fully. To maximize this reassurance, an automatic locking security door system provides safety for staff, faculty, parents and students. Students and staff are trained in District procedures to vacate the building should there ever be an actual emergency. Drills are conducted to ensure safe evacuation in the event of a true need.
