The full form of TBD in education, as in other contexts, is To Be Determined.
This acronym is used to indicate that specific details, such as the date, time, location, or other aspects of an event, assignment, or course component, have not yet been finalized and will be announced later. For instance, "The final exam date is TBD" signifies that the exam date hasn't been decided and students should await further announcement.
In educational settings, TBD provides flexibility but also requires students and staff to remain informed and check for updates regularly. It implies that decisions are still pending, and details will be communicated once they are confirmed.
