 The lower exploratory high school system is now called "Junior High School" (Grades 7–10) while the upper specialized high school system is now called "Senior High School" (Grades 11 and 12).Secondary students used to sit for the National Secondary Achievement Test (NSAT), which was based on the American SAT, and was administered by the Department of Education.Like its primary school counterpart, NSAT was phased out after major reorganizations in the education department.
