Pisay GWA Calculator
Compute your Philippine Science High School (PSHS / Pisay) GWA on the 1.00–5.00 scale — where 60% is the passing mark, not 75%. Grade table, Director's List and honors, free, no sign-up.
Calculate your Pisay GWA
1.00–5.00 scale · 60% passing
Grades use the Pisay 1.00–5.00 scale (1.00 is best, 5.00 is fail). Your grades never leave your browser.

| Grade | Percentage (as reported) |
|---|---|
| 1.00 | 96–100% |
| 1.25 | 90–96% |
| 1.50 | 84–89% |
| 1.75 | 78–83% |
| 2.00 | 72–77% |
| 2.25 | 66–71% |
| 2.50 | 60–65% |
| 2.75 | 55–59% |

PSHS grades on percentages internally and reports the transmuted grade on the 1.00–5.00 scale — the table above is the one reported in the PSHS Student Handbook. The handbook names five of the grades: 1.00 Excellent, 2.50 Satisfactory, 3.00 Unsatisfactory, 4.00 Conditional Failure and 5.00 Failed. The big difference from other Philippine schools is the passing mark: 60% (a grade of 2.50) instead of the usual 75%. A 2.50 at Pisay is a passing grade; at most other schools it would be a comfortable pass, and a 60% anywhere else would be a fail. Note the scale has no 3.00-passing concept at all: 3.00 at Pisay is 50–54%, Unsatisfactory, and already a warning grade. For the usual 1.00–5.00 table used by Philippine colleges, see the Grade Equivalents page — and if your school is not PSHS, use the GWA Calculator instead, because its 3.00 passing mark does not apply here.
How Pisay computes grades each quarter
Two Pisay-specific details, as reported in the PSHS Student Handbook. First, quarterly grades are cumulative: except for first-quarter grades, each quarter's grade is (tentative grade × 2 + previous quarter's grade) ÷ 3 — two-thirds the grade earned for the current quarter and one-third the transmuted grade from the previous quarter. So a strong first quarter keeps helping you, and a weak one keeps costing you, into the next quarter. Second, the GWA itself is the usual weighted average: grade × units, added up, divided by total units, exactly as the How to Compute GWA guide shows. The calculator above uses that formula with the grades from your report card.
Good standing, warning and probation
Pisay is a scholarship school, and the standing rules are stricter than at most schools. As reported in the PSHS Student Handbook:
- Good standing — a grade of 2.50 or better in every subject each quarter, and a GWA of 2.25 or better.
- Warning — a final grade of 2.75 or 3.00 in any one subject, or 4–7 days of unexcused absences.
- Probation — 2.75 or 3.00 in two or more subjects, up to one-third of your total units for the year.
- Dismissal risk — a 5.00 in any subject, or grades below 2.50 in more than one-third of your units, or two successive probationary statuses.
That is why a 2.75 at Pisay matters more than the same number elsewhere: on the usual college scale it is a passing grade, but at Pisay it is already a warning. If any of these apply to you, talk to your adviser early — the standing decision is made for the incoming school year, and there is usually a process to clear it.
Director's List and graduating honors
The PSHS honor roll is the Director's List: as reported in the PSHS Student Handbook, a GWA of 1.00–1.50 each quarter/semester qualifies a scholar for the list. For graduating students, the academic awards are With Highest Honors (GWA 1.0–1.20) and With High Honors (GWA 1.21–1.50), computed from the GWA over all four year levels — first year × 1, second year × 1, third year × 2, fourth year × 2, divided by 6. That weighting means your last two years count double. The Dean's Lister guide explains how the per-semester list at colleges differs from this quarterly list.
Worked example
Four subjects, one quarter. Multiply each grade by its units, add the results, then divide by total units.
| Subject | Grade | Units | Grade × Units |
|---|---|---|---|
| Math 101 | 1.00 | 3 | 3.00 |
| English 101 | 1.25 | 3 | 3.75 |
| Science 101 | 1.50 | 3 | 4.50 |
| Filipino 101 | 1.75 | 2 | 3.50 |
| Total | 11 | 14.75 |
Step by step: Math 101: 1.00 × 3 = 3.00; English 101: 1.25 × 3 = 3.75; Science 101: 1.50 × 3 = 4.50; Filipino 101: 1.75 × 2 = 3.50. Add the results: 3.00 + 3.75 + 4.50 + 3.50 = 14.75. Add the units: 3 + 3 + 3 + 2 = 11. Divide: 14.75 ÷ 11 = 1.34.
GWA = 1.34. That is a strong GWA — inside the reported Director's List range (1.50 or better). Try the same numbers in the calculator above — you will get 1.34. Remember that your quarterly grade also carries one-third of the previous quarter with it, so the GWA on your report card may differ slightly from this single-quarter calculation; for a whole-course number, use the Cumulative GWA Calculator, and for the SHS version of this calculation, see How to Compute GWA in SHS.
