CSD is a suburban school district with 7 schools. For the 2026-2027 school year, classes begin August 31 and end June 11. Colonial School District covers Conshohocken Borough and Plymouth and Whitemarsh townships in Montgomery County, PA, and has been recognized as a 2026 Best Community for Music Education and an Outstanding Visual Arts Community by the Pennsylvania Art Education Association. The district has said a complete 2026-2027 calendar — including early dismissal dates — will be published soon. The calendar also notes several religious observances (Holiday (Yom Kippur), No School for Students/Teachers (Eid Al Fitr)) for awareness — school stays in session on these days. This calendar includes 2 professional development days, 1 early-release or half day — useful to know when planning childcare. The last day of school is tentatively set for June 11, but may move if the district needs to use weather makeup days.
