Academic credits are units that measure the amount of coursework a student has completed at an educational institution. Typically, one credit represents one hour of classroom instruction per week over a semester. Students earn credits by successfully completing courses, which contribute to their overall progress toward a degree or certification. The total number of credits required for graduation varies by program and institution. For example, a bachelor's degree often requires around 120 credits, while an associate degree may require about 60 credits. Institutions use these credits to ensure students meet the necessary academic standards and gain the knowledge needed in their field of study.
