Senior secondary education (Grades 10-12) is for students between the ages of 16 and 19 years.

At the end of Senior Secondary/High School (twelfth grade), all students take the West African Senior Secondary Certificate Examination, (WASSCE), or International General Certificate of Secondary Education (IGCSE) for some of the private schools. These exams are given nationwide in May-June each year, but the results are not available until the following October. The minimum university standard for admission to post-secondary education is 5 credits on the WASSCE, including credits in math and English. U.S. universities normally do not admit Gambian students who have not attained at least this level. Students are expected to retake exams in subjects they have failed.
