If you’re a student from Ireland aiming to apply to a U.S. university, understanding how to convert your grades to the U.S. 4.0 GPA system is essential. Ireland uses a distinct grading structure that reflects both academic achievement and competency. Let’s explore how the Irish grading system works and how you can translate it into a U.S.-recognized GPA format.
The Irish Grading System
Ireland primarily follows a percentage-based grading system at both secondary and higher education levels. However, the grading scales can vary slightly depending on the institution, especially between secondary schools and universities.
Secondary School (Leaving Certificate) Grading System
The Irish secondary school system uses the Leaving Certificate as the standard qualification for university admissions. The grading scale was updated in 2017 to a new system, which includes both Higher and Ordinary level exams. Here’s how the Leaving Certificate grading works:
| Grade | Percentage Range | Description | Points (Higher Level) | Points (Ordinary Level) |
|---|---|---|---|---|
| H1 / O1 | 90–100% | Excellent | 100 | 56 |
| H2 / O2 | 80–89% | Very Good | 88 | 46 |
| H3 / O3 | 70–79% | Good | 77 | 37 |
| H4 / O4 | 60–69% | Satisfactory | 66 | 28 |
| H5 / O5 | 50–59% | Pass | 56 | 20 |
| H6 / O6 | 40–49% | Pass | 46 | 12 |
| H7 / O7 | 30–39% | Pass | 37 | 0 |
| H8 / O8 | 0–29% | Fail | 0 | 0 |
- H1–H7 are for Higher Level exams.
- O1–O8 are for Ordinary Level exams.
University Grading System
Irish universities use a letter-based system similar to the U.K. classification model:
| Grade | Percentage Range | Description |
|---|---|---|
| First-Class Honours (1:1) | 70–100% | Excellent |
| Upper Second-Class Honours (2:1) | 60–69% | Very Good |
| Lower Second-Class Honours (2:2) | 50–59% | Good |
| Third-Class Honours | 40–49% | Satisfactory |
| Fail | Below 40% | Fail |
- Some universities may use variations like “Distinction,” “Merit,” or “Pass” for postgraduate programs.
- Assessment is typically based on a combination of coursework, exams, and practical performance.
The US 4.0 GPA System
The U.S. GPA system assigns numerical values to letter grades to calculate an overall score out of 4.0. This helps admissions offices compare academic performance across different educational systems.
| Letter Grade | GPA Value | Percentage Range (Typical) |
|---|---|---|
| A | 4.0 | 90–100% |
| B | 3.0 | 80–89% |
| C | 2.0 | 70–79% |
| D | 1.0 | 60–69% |
| F | 0.0 | Below 60% |
- Unweighted GPA only considers the letter grade.
- Weighted GPA considers course difficulty, such as honors or AP courses, but this is less common for international applications.
The Conversion Process
Converting Irish grades to the U.S. GPA system involves assigning approximate GPA values to Irish grades. Follow these steps:
- Collect your grades: Get your official transcript, including percentage-based grades and letter classifications.
- Match Irish grades to U.S. equivalents: Use the table below to translate your grades.
- Assign GPA values: Apply the corresponding GPA value from the U.S. system.
- Calculate your GPA: Add up all GPA values and divide by the number of courses.
Conversion Table
| Irish Grade | Percentage Range | U.S. Equivalent | U.S. GPA Value |
|---|---|---|---|
| H1 / First-Class Honours | 70–100% | A | 4.0 |
| H2 / Upper Second-Class Honours | 60–69% | B | 3.0 |
| H3 / Lower Second-Class Honours | 50–59% | C | 2.0 |
| H4 / Third-Class Honours | 40–49% | D | 1.0 |
| H5–H8 / Fail | Below 40% | F | 0.0 |
Example:
Suppose you received the following grades from your Irish university:
- First-Class Honours (75%)
- Upper Second-Class Honours (65%)
- Lower Second-Class Honours (55%)
- Third-Class Honours (45%)
Using the table:
- First-Class Honours = 4.0
- Upper Second-Class Honours = 3.0
- Lower Second-Class Honours = 2.0
- Third-Class Honours = 1.0
Total GPA Points = 4.0 + 3.0 + 2.0 + 1.0 = 10.0
Number of Courses = 4
Final GPA = 10 ÷ 4 = 2.5
✅ Your U.S. GPA = 2.5

Common Questions Answered
Q: Is the conversion table always accurate?
A: It’s a general guide. Some universities may weigh Irish grades differently based on competitiveness or institutional policies.
Q: How do I handle Honours distinctions?
A: First-Class Honours typically translates to a 4.0, but some U.S. universities may calculate it differently. Always check with your target university.
Q: What if my school uses a Pass/Fail system?
A: A passing grade (H5–H7) generally converts to at least a 1.0 in the U.S. GPA system. If your transcript only lists Pass/Fail, consult the university’s admissions office for guidance.
Q: Can I raise my GPA if I have lower grades?
A: You can improve your GPA over time with stronger academic performance. Check out these resources on How to Raise GPA.
Final Tips
- Focus on maintaining a strong average in your Irish coursework to achieve a higher U.S. GPA equivalent.
- Double-check your transcript for accuracy before submitting it to U.S. universities.
- Use a tool like the College GPA Calculator to double-check your calculation.
