What Is the U.S. Public School Grading System?
The U.S. public school grading system evaluates student performance using A–F letter grades, 1–4 numeric scales, or Pass/Fail marks, depending on the grade level and district.
GPA (Grade Point Average): A cumulative score (0.0–4.0) used mainly in secondary schools and for college admissions.
A–F Grades: Common in middle and high schools; A = excellent, F = failing.
1–4 Scale: Used in elementary schools to measure proficiency on standards.
Pass/Fail: Applied to electives or non-core subjects.
E, S, N, U Grading System
The E, S, N, U grading system is commonly used in kindergartens and early elementary levels to assess developmental progress rather than academic rigor. Here’s how it works:
- E (Excellent): Consistently exceeds expectations.
- S (Satisfactory): Meets grade-level expectations.
- N (Needs Improvement): Progressing but below grade-level expectations.
- U (Unsatisfactory): Significant improvement required.
This system encourages development-focused feedback, emphasizing growth over competition.

1-4 Rating System
The 1-4 numeric grading scale is popular in elementary schools for its simplicity and clarity. Here’s a breakdown:
- 1: Beginning to grasp skills.
- 2: Developing proficiency.
- 3: Meeting standards.
- 4: Exceeding expectations.
This system is particularly effective for younger learners, as it aligns with developmental milestones and reduces performance pressure.
Pass/Fail Systems
Pass/fail grading, often used in early education or elective courses, eliminates traditional letter grades and instead signals whether students meet basic course standards.
While it reduces stress, critics argue it can mask true academic performance.
- High Schools: Some elective courses use Pass/Fail to encourage exploration without grade pressure.
- Colleges: Advanced courses may offer H (High Pass) or I (Incomplete) to reflect nuanced performance.
This system eliminates competition but may lack detailed performance insights.

Comparison of Grading Systems
Here’s a detailed comparison of common grading systems in the U.S.:
System | Usage | Strengths | Challenges |
---|---|---|---|
A-F | High schools, colleges | Precise performance measurement | Can add pressure |
1-4 | Elementary schools | Simple for young learners | Less detailed |
E, S, N, U | Kindergartens, early grades | Encourages development-focused feedback | Inconsistent adoption |
Pass/Fail | High schools, colleges | Reduces competition, stress | Lacks detailed performance feedback |

What is the A-F Grading Scale?
The traditional A-F grading scale is the most common method used in U.S. public schools to evaluate student performance. Each grade corresponds to a specific percentage range and represents a student’s mastery of course material.
Grade | Percentage Range | Descriptor |
---|---|---|
A | 90-100% | Excellent |
B | 80-89% | Good |
C | 70-79% | Average |
D | 60-69% | Below Average |
F | Below 60% | Failing |

These systems can promote equity and reduce stress, but they also come with challenges, such as difficulty in translating grades for college admissions. Learn more about alternatives in Pros and Cons of Standardized Testing.
The Role of Grading Systems in Education
Grading systems influence academic tracking, motivation, and equity. However, challenges like grade inflation and disparities in grading policies raise questions about fairness. Educators and policymakers must strive for balance to ensure grades accurately reflect student learning.
How Colleges View Different High School Grading Systems
College admissions officers are well-versed in interpreting different grading formats. According to the National Association for College Admission Counseling (NACAC):
- Letter Grades and Weighted GPAs are still the most common metric.
- Standards-Based Transcripts (used in some California and Vermont districts) are accepted but often require conversions.
- Pass/Fail Grades are evaluated cautiously. A “P” in a core subject may trigger requests for additional information.
- Admissions offices look for:
- Rigor of coursework (AP, IB, Honors).
- Trends (Did GPA rise junior year?).
- Contextual factors provided by school counselors.
If your school uses a non-traditional system, make sure your school profile clearly explains it — most colleges will adapt.
