Calculating a grade point average (GPA) according to the standards set by the Coursework Authentication Service (CAS) involves assigning numerical values to letter grades earned in academic coursework. These values are typically weighted based on credit hours. The assigned numerical grade for each course is multiplied by the course’s credit hours. These products are then summed, and the result is divided by the total number of credit hours attempted. For example, an ‘A’ might be worth 4.0, a ‘B’ 3.0, and so on. A three-credit course where an ‘A’ was earned would contribute 12.0 (4.0 x 3) to the overall calculation.
A GPA calculated using a CAS methodology is frequently utilized by professional schools and graduate programs for admissions purposes. A standardized calculation allows for a fair and consistent comparison of academic performance across diverse undergraduate institutions, some of which may employ different grading scales or GPA calculation methods. This standardization ensures a more equitable evaluation process, reducing inconsistencies that might arise from differing institutional practices.
