Calendar
Derby High School's school day starts at 7:55AM (8:55AM on Mondays) and ends each day at 3:10PM.
Why do we have Late Start Mondays?
Late Start Mondays give teachers dedicated time for Professional Learning Time (PLTs). During this time, educators collaborate on curriculum, instructional strategies, review student data, and receive training on technology and other tools — all to better support student learning.
