Grades are interpreted as follows:
| A = 93 - 100 | Superior Work | Scale of Conduct: Satisfactory Conduct |
| B = 86 - 92 | Above Average Work | |
| C = 77 - 85 | Average Work | |
| D = 70 - 76 | Below Average Work | |
| F = 0 - 69 | Failing Work | |
| I = | Incomplete Work |
Reports for the first and third quarters are distributed to all parents at parent-teacher conferences. Reports for first and second semester are mailed home. St. Dominic High School uses the Edline program as a means to communicate up-to-date grades for each student electronically with the student and his/her parents.
Exams are given at the end of each semester. The exam grade will count for 20% of the semester grade. Semester grades are calculated by averaging the two quarters in the semester along with the semester exam. Each quarter receives 40% weight while the exam is weighted 20% of the semester grade.
