There are many different ways a high school student can earn credits through online courses. One may take up the Advanced placement program or the International Baccalaureate program. However, these courses have an advanced curriculum and most of the high-schoolers do not opt for them.

So read on!

What are High School Course Credits?

A credit is a recognition for having taken a course at high school and measuring if a course is taken for enough hours towards graduation. So, credits are the primary method used to determine whether a student has met academic requirements.

Generally, high schools measure credits based on the Carnegie Unit. The system determines the number of academic credits a student has earned based on the number of hours spent in the classroom. As per the standard Carnegie Unit, a student has to have 120 hours of contact time with the instructor. This includes one hour of classroom instruction, five days a week for twenty-four weeks.

Most of the public high schools in the United States follow the Carnegie -Unit system for the allocation of credits. To be eligible for a diploma, a student has to earn 18-24 credits. Each of the earned credits represents one Carnegie Unit.

Schools and districts are responsible for determining the credit requirements. However, the state policies set the minimum credit requirement criteria. For instance, if the minimum credit requirement for a state is 18, the high school may choose to raise it to 25.

The credit requirements might vary from school to school and state to state. However, the outline for minimum credits required is almost the same for the core subject areas. These subjects generally make up for a major part of the high school curriculum.

The credit requirements needed to graduate high school largely vary between school to school and state to state. The progress towards graduation largely depends on a student’s ability to earn required credits in core subjects and electives.

According to the National Centre of Statistics report, the total credits required for graduation can go as high as 26 in Texas to 13 in Wyoming. For core subject areas like language arts, social studies, science, and math, a student has to earn 4 credits each. Also, high school electives make up for a minimum of 6 and a maximum of 11 credits in different states.

However, in California, local school districts set the minimum local units required to earn a high school diploma. A student has to take almost 26 year-long courses in public high schools in California. Two-semester courses constitute a one-year-long course. One year-long course is equivalent to one Carnegie Unit. Most of the school districts in California award ten local units for one Carnegie Unit, and five for a semester course. Overall, the California school districts require a student to earn 220 to 260 local units to earn the high school diploma.

For an instance, the Pleasanton School District in California requires a student to earn 230 local units to graduate high school. The student has to earn the following number of local units at the end of each semester:

Grade 9:

Semester 1: 25 local units

Semester 2: 50 local units

Grade 10:

Semester 1: 80 local units

Semester 2: 110 local units

Grade 11:

Semester 1: 140 local units

Semester 2: 170 local units

Grade 12:

Semester 1: 200 local units

Semester 2: 230 local units total.

Credits are the primary method to measure if a student has met the academic requirements necessary to graduate. Generally, high schools measure credits based on the Carnegie Unit. The system assigns academic credits based on the number of hours a student has spent in the classroom.

Most of the public schools in the U.S require students to earn 18-24 academic credits to graduate. However, in California, schools use up the local units to award academic credits. Ten local units are equivalent to one Carnegie Unit. However, the state determines the minimum graduation requirements and a school can decide to increase it. For instance, if a state’s graduation requirement is 18, a school can increase it to 24 credits.

A student has to earn 4 credits each in math, science, social studies, and language to earn the high school diploma. Also, electives make up for at least 7 credits in high school.

Amongst the free resources where high schoolers can take credit-backed courses, edX and Coursera are the most popular. edX provides over 2500 courses for free. For credit-backed programs, high schoolers can check out the Global Freshman Academy program at edX.
