In order to comply with state law and to ensure continuous and appropriate progress through Grades 9–12, the Lexington One Board of Trustees has established Administrative Rule IHE-R attached to the district’s Promotion and Retention Policy, IHE. Students are promoted or retained in grade classifications based on these criteria. In Grades 9 through 12, in order to be eligible for promotion to the next grade classification, students must have earned a minimum number of units, as specified below.

To be promoted to Grade 10, second-year students must have earned a minimum of five units. They must have at least one unit each in language arts and mathematics and be enrolled in courses leading to an additional unit of credit in both language arts and mathematics.

To be promoted to Grade 11, third-year students must have earned a minimum of 11 units. Those units must include two language arts and two mathematics courses.

To be promoted to Grade 12, fourth-year students must have earned a minimum of 16 units. Students must have earned at least two units each in English and mathematics and be enrolled in coursework for the following year that will allow them to complete the 24 units needed for the South Carolina High School Diploma.

At any time during the fourth year of high school that a student is enrolled in the necessary courses to graduate, whether onsite or virtual, the student will be assigned senior status. A student who plans to graduate in less than four years must complete the necessary application form, which may be obtained through the Counseling Office.
