Marking System  - Grades are reported two times a year. Oak Hill uses a satisfactory scale for the Lower School (grades K-5), and letter grades for Upper School (grades 6-12). A's are given only for exceptional performance. A- is an honors grade. B is a college recommending grade. Grades for Advanced Placement courses are weighted to reflect the academic rigor of these classes.

Communication with Parents – Every Friday, Grades K-8 receive a Friday Folder. In this folder, each student’s teacher summarizes the week’s work. The teacher identifies how the student is progressing and opportunities for improvement. Mid-term, Upper School parents receive written progress reports about each student. It is not uncommon for teachers to communicate with parents via phone or email if a significant shift in performance is noticed.

Honor Societies -  Students who maintain a 3.65 GPA are invited into Oak Hill School’s Honor Society. Membership in the American Technology Honor Society requires membership in the National Honor Society in addition to a 3.8 overall GPA.
