A PD day, or professional development day, is a day set aside for teachers and staff to learn new skills, collaborate with others, and further develop their expertise. PD days provide time for staff to work together on things that impact a certain grade level or subject matter team. During these days, teachers may be taught new skills, such as new teaching methods or ways to incorporate technology into their classrooms. They may also analyze student data, attend workshops, or receive training on specific skills that can support students and teachers. PD days are essential in giving teachers, administrators, and support staff uninterrupted time to collaborate, learn, and improve. Students usually have the day off on PD days, which gives them an extra-long weekend and more time to play or relax.
