Grading System and Marking System for Secondary Schools and O Levels Singapore
Secondary schools are the first institutions in Singapore to have implemented the “Overall Grade” grading system for academic subjects. Since the 2000s, the education system allows more capable Normal (Academic) stream students to participate in the O Levels examination for Mother Tongue and Mathematics (Elementary) a year instead of taking the N Levels equivalents. This has resulted with a quasi-O Levels grading system used for such students, although their N Levels subjects are graded along the Overall Grade grading system, thus in their result slip, some subjects will be graded along the Overall Grade, and some with the O Levels grading system.
Express and Special stream students are graded along the Overall Grade grading system for the first 3 academic years in their secondary schools, and then graded along the O Levels grading system in their final secondary school year (year 4). Normal (Academic) students are graded for first 3 academic years and the N Levels year (year 4), and subsequently graded along the O Levels grading system in their final secondary school year (year 5). Normal (Technical) stream students are graded along the Overall Grade grading system throughout their entire education in secondary schools.
Non-academic subjects like Religious Knowledge, Civic & Moral Education and Music are graded with an alphabetical grading system of A, B, C or D.
Overall Grade
- A1: 75% and above
- A2: 70% to 74%
- B3: 65% to 69%
- B4: 60% to 64%
- C5: 55% to 59%
- C6: 50% to 54%
- U: Below 50%, considered Un-graded, or failed.
GPA
In some Secondary Schools, Grade Point Averages are used. The Grade Point Average is calculated by taking the Grade Point of each subject, adding them together, then dividing the total by the amount of subjects the student takes. This value is rounded to two decimal places, giving the student's GPA. A minimum GPA of 2.0 will usually be required for promotion.
For example, the GPA table for Raffles Institution is as below:
| Grade | Percentage | Grade Point |
|---|---|---|
| A+ | 80-100 | 4.0 |
| A | 70-79 | 3.6 |
| B+ | 65-69 | 3.2 |
| B | 60-64 | 2.8 |
| C+ | 55-59 | 2.4 |
| C | 50-54 | 2.0 |
| D | 45-49 | 1.6 |
| E | 40-44 | 1.2 |
| F | <40 | 0.8 |
However, in other secondary schools, there is also a system called MSG (mean subject grade) which is similar to GPA that is used.
| Grade | Percentage | Grade Point |
|---|---|---|
| A1 | 75-100 | 1 |
| A2 | 70-74 | 2 |
| B3 | 65-69 | 3 |
| B4 | 60-64 | 4 |
| C5 | 55-59 | 5 |
| C6 | 50-54 | 6 |
| D7 | 45-49 | 7 |
| E8 | 40-44 | 8 |
| F9 | <40 | 9 |
The mean subject grade is calculated by adding the points together, then divided by the number of subjects. For example, if a student got A1 for math and B3 for English, his MSG would be (1+3)/2 = 2.
NA Levels Grades
- 1: 75% and above
- 2: 70% to 74%
- 3: 65% to 69%
- 4: 60% to 64%
- 5: 50% to 59%
- U: Below 50%, considered Un-graded, or failed.
NT Levels Grades
- A: 75% and above
- B: 70% to 74%
- C: 60% to 69%
- D: 50% to 59%
- U: Below 50%, considered Un-graded, or failed.
O Levels Grades
- A1: 75% and above
- A2: 70% to 74%
- B3: 65% to 69%
- B4: 60% to 64%
- C5: 55% to 59%
- C6: 50% to 54%
- D7: 45% to 49%
- E8: 40% to 44%
- F9: Below 40%
- Grades D7, E8 and F9 are considered the failing grades. Students taking Mother Tongue Syllabus B may be awarded a Distinction, Merit, Pass, or a Fail grade.
