A standard system of weighted percentages is used for recording student progress. To remain in good standing, a student must maintain an average of 80% or better.
If a student’s average falls below 80%, he or she may be permitted to continue in school for an additional time period established at the time of a progress report. During this time, the student is required to pass coursework with grades that will bring his/her average up to satisfactory. This period is considered probationary. If grades are not brought up to passing, the student will be terminated for unsatisfactory progress. At this point, veterans benefits may be interrupted. Re-entry will be at the discretion of the School’s administration.
