4th-Year Elective Block Dates: B.U. School of Medicine

Boston University School of Medicine (BUSM) divides its fourth (final year) curriculum of medical school classes (electives) into 4-week blocks as listed below. International students who apply for an elective at BUSM must choose from the blocks below. The block dates cannot be altered.

Notes on Block Dates

  • Blocks begin on Mondays.
  • Block end dates are listed below as Sundays, but most electives end on the Friday before that. E.g., block 10 ends 7/28/2019, but the final day will most likely be 7/26/2019.
  • Federal U.S. holidays:  If a federal holiday falls on a Monday, electives may begin on the Tuesday and not the Monday. Elective coordinators will confirm with students with this information. Federal holidays that may affect the Monday start date are:
    • January 20, 2020 (Martin Luther King, Jr. Day) – block 17
    • February 17, 2020 (President’s Day) – block 18
