Oakbrook Preparatory School

Administrator Login

All Carnegie Unit courses offered by Oakbrook will be designated and weighted as College Preparatory, Honors, or Advanced Placement. Students will be encouraged to pursue Honors level work based on standardized test scores, academic performance (minimum B average), and a teacher recommendation. The rigor of the honors curriculum will prepare students for the opportunity to select Advanced Placement courses in their Sophomore, Junior, and Senior years.

Carnegie Units

The South Carolina Uniform Grading Scale and the system for calculating GPAs and class rank will apply to all courses carrying Carnegie units, including units earned at the middle high school level (i.e. Algebra I, Geometry, Physical Science, and level one world language.)

See the Family Handbook here for a printable copy of the South Carolina Uniform Grading Scale.

Levels of Courses

CP: These courses are designed to fulfill the requirements to earn a high school diploma and prepare students for college. They earn weighted grade points as designated on the South Carolina Uniform Grading Scale.

HONORS: These courses are designed to be academically challenging and preparation for advanced placement courses.

AP (Advanced Placement): These courses are designed to be academically challenging and are taught on the college level. AP courses follow the curriculum provided by the College Board. College Board National AP Exams are in May of each year. Students should contact specific colleges to learn of their specific policy concerning awarding advanced placement credit.

Grade Point Averages

All Carnegie Unit courses offered by Oakbrook will be designated and weighted as College Preparatory, Honors, or Advanced Placement. Students will be encouraged to pursue Honors level work based on standardized test scores, academic performance (minimum B average), and a teacher recommendation. The rigor of the honors curriculum will prepare students for the opportunity to select Advanced Placement courses in their Junior and Senior years. Students will need to maintain a B average in order to remain in honors classes. 

See Family Handbook for South Carolina Uniform Grading Scale and general grading information.

For example:
A grade of 100 will carry a CP weighting of a 5.0, an Honors weighting of 5.5, and an AP weighting of 6.0.  A grade of 90 has a CP weighting of 4.0, an Honors weighting of 4.5, and an AP weighting of 5.0.

Some scholarships, however, may be based on unweighted values.  For these calibrations, every A is weighted as a 4.0, every B as a 3.0, every C as a 2.0, and every D as a 1.0.

*The 10-point grading scale, adopted by Oakbrook in 2016-17, is not retroactive.  All previous GPA credits, acquired on the previous grading scale, will remain untouched.  

GPA/Class Rank

Grade point averages and class rank are determined using the South Carolina Uniform Grading Scale. Class rank is not distributed to colleges.

Valedictorian/Salutatorian

The GPA and/or class rank is used for school activities requiring rank placement such as top GPA award (presented to student with highest GPA in grades 9, 10, and 11); junior marshals (top six in junior class) and various senior honors and scholarships. The valedictory and salutatory awards are presented to the seniors with ranks of one and two, respectively.
