Dayton schools face short summer, leadership turnover Jeremy P. Kelley Dayton’s school board on Tuesday approved a “back-to-normal” school calendar for 2021-22, and approved yet another district leader’s resignation. Dayton Public Schools students will be in class through June 29 this year because DPS was the only district to completely stop classes between Thanksgiving and Christmas as COVID cases surged. After a short seven-week summer, students will be back in class Aug. 18. The 2021-22 calendar has its normal holiday and spring breaks, and a May 27 last day for students. Teachers, who are regularly involved in building these calendars, get a six-week summer, then start work Aug. 12 and finish May 31.
