With the enactment of the K-12 reforms, secondary education was extended from four to six years and divided into two levels: four years of Junior High School (JHS) and two years of Senior High School (SHS), giving the basic education cycle a structure of K+6+4+2. JHS comprises grades 7 to 10 (ages 12 to 16). Students who complete elementary education at grade 6 automatically progress to JHS. The JHS core curriculum includes the same subjects as the elementary curriculum, with English and Filipino being used as the language of instruction, depending on the subject. Students are assessed based on written assignments, performance tasks and quarterly assessments (based on tests and/or performance tasks). The minimum passing grade for both single subjects and the cumulative year-end average required for promotion is the grade of 75 (out of 100). Students with lower grades must take remedial classes and improve their grades in order to progress to the next grade.
