U.S. elementary teachers spend an average of about 32 hours a week with their students, secondary teachers about 30 hours, out of a 38-hour contractual week. Daily planning time ranges from 12 to 80 minutes for elementary teachers, from 30 to 96 minutes at the secondary level. The paucity of contractual planning time in most schools pushes a lot of teachers’ work into late afternoons, evenings, and weekends; including that time, the typical teacher’s work week is about 52 hours.
