US Credit System: Structure, Types of Credits, and Relation with GPA

Content Writer - Study Abroad | Updated On - Nov 12, 2024

US credit system in higher education is a framework used to measure and record students' academic progress and achievement. It measures the time spent in a class, not your performance. Your academic performance is measured by GPA or Grade Point Average. For example, 120-130 credits in 4 years are required for a bachelor degree in USA, while, 30-60 credits in 1-2 years are required for a master degree. The credit system in education provides a standardized approach to gauge how much time students spend learning, both in and out of the classroom, and how well they have achieved the educational objectives of their courses.

Since colleges in USA only have 2-3 classes each week, the credit hour system is widely used to calculate the academic progression of a student. Depending on the number of class hours per week, each course has a different number of credit hours. For example, if a course has classes three times per week, it is worth three credit hours.

How many hours is a 4 credit course?

A 4 credit course is 180 credit hours. Each credit hour corresponds to a minimum of 3 hours of student engagement per week for a traditional 14-week course or 6 hours per week for a 7-week course. Each credit hour has one hour of lecture time in class per week. Credit hours are one of the important factors in the US education system.

Credit hours determine if you need to take a preparatory course to meet the admission requirements of a bachelor and master degree.
Universities like Webster University, University of Central Missouri, University of New Haven set their tuition fees as per the credit hours required for a specific course.
If you enroll in fewer than 12 credit hours in college, you'll be considered as a part-time student.

Structure of US Credit System

The credit system in USA universities is based on three elements:

Contact Hours: This refers to the actual hours spent in a classroom setting, with each credit hour equating to roughly one hour per week in class.
Independent Study: For each hour in class, students are expected to spend about two additional hours on homework, reading, projects, and preparation.
Credit Value of Courses: Most undergraduate courses are valued at 3 credits, though some may vary based on content and structure.

Note: 1 credit = hours 3 (1 hour of classroom setting + 2 hours of outside class work per week)

Types of Credits in US Credit System

The credit system in college in USA includes different types of credits, which influence degree progress:

Core Credits: These are required courses within a student’s major or concentration and are essential for developing expertise in their primary area of study.
Elective Credits: Courses chosen outside a student’s primary field, allowing them to explore other interests or supplement their major. Elective credits are flexible but still count toward the degree total.
General Education Credits: These credits cover foundational subjects such as math, science, social studies, and humanities, ensuring that students receive a well-rounded education.

Types of Credit Hours in US Credit System

Depending on your chosen university in USA, there are mainly three types of credit hours:

Semester credit hours: How many hours is a 4 credit course per semester? A semester credit hour refers to the credit hour earned during the completion of one hour (50 minutes) of class for a course during a week in one semester of the academic year. The number of classes per week determines the credits for the corresponding course.
Quarter hours or trimester hours: Some US universities/institutions use the quarter calendar system, where the academic year is divided into 3 quarters of about 11 weeks each. They are divided on the basis of 3 seasons, namely the fall, spring, and summer. In the quarter system, students have more flexibility and time to choose many courses. One-quarter hour is 1.5 times one semester hour. So, a typical bachelor’s degree in the US will have 180 quarter hours.

Credit Hours Required to Complete a Course

A course is measured in the number of Credit Hours needed to complete it. For an undergraduate degree, basic courses may have 1 credit or 2 credits. In a Master’s degree, including MBAs, most courses are either 3 or 4 credits. A standard full-time study load is usually 30 credit hours per year. Hence, you have to complete the following credit hours to get an undergraduate and graduate degree

How many credit hours for 4 year degree: 120-130 credit hours
30-60 credit hours for a graduate degree or MS in USA

Check how many hours are required for a 7-week, 8-week and 14-week course from the table below

Credits	Hours Required for a 7-week Course	Hours Required for a 8-week Course	Hours Required for a 14-week Course
1 credit	6 hours	5 hours	3 hours
3 credit	18 hours	16 hours	9 hours
6 credits	36 hours	32 hours	18 hours
12 credits	72 hours	63 hours	36 hours

Relation Between GPA and Credits

Credits also contribute to calculating a your Grade Point Average (GPA), an essential measure of academic performance. Each course’s grade is assigned a point value (for example, A = 4.0, B = 3.0) and multiplied by the credit hours for that course. The sum of these values is then divided by the total credit hours attempted to find the GPA. In short, the process is as follows

Multiply the point value of the letter grade by the number of credit hours. The result is the quality points (grade points) earned for the course.
Total the quality points for all terms.
Total the credit hours for all terms.
Divide the total quality points for all terms by the total credit hours for all terms.
The result is your cumulative GPA.

Example:

Step 1:
A (4.0) x 3 credit hours = 12.0 quality points
A- (3.7) x 2 credit hours = 7.4 quality points
B+ (3.3) x 4 credit hours = 13.2 quality points

Step 2:
Total quality points = 32.6

Step 3:
Total credit hours = 9

Step 4:
32.6 / 9 = 3.62 cumulative GPA

US Credits to ECTS: Differences and Conversion

ECTS stands for European Credit Transfer and Accumulation System. It is a tool to measure students’s progrees in aN European university. The European Credit Transfer and Accumulation System (ECTS) and US credit systems use different measures for academic credit.

Conversion: 1 US credit hour equates to about 2 ECTS credits. This means that a standard 3-credit US course corresponds to approximately 6 ECTS credits.
Credit Hour Calculation: US credits are based on time spent in class and independent study per week, while ECTS credits reflect total workload, including all learning activities. ECTS expects about 25-30 hours of total student effort per 1 ECTS credit.
Full-time Study Load: In the US, a full-time load is generally 15 credits per semester, equating to about 30 US credits annually. In the ECTS system, a full-time workload is 60 ECTS credits per academic year.

Thus, 30 US credits in one academic year are roughly equivalent to 60 ECTS credits.

Some US universities like Southern New Hampshire University, Northern Arizona University are adopting competency-based credits. It assess students on skills mastery rather than seat time. This allows students to advance at their own pace, which can be beneficial for non-traditional learners or students with prior knowledge or experience.
