Course Grading System
Idaho State University uses letter grades with the four (4) point maximum grading scale. The grade A is the highest possible grade, and a grade of F is considered failing. Plus (+) or minus (-) symbols are used to indicate grades that fall above or below the letter grades. The grades of A+, F+, and F- are not used. For purposes of calculating grade points and averages, the plus (+) is equal to .3 and minus (-) equals .7 (e.g., a grade B+ is equivalent to 3.3 and A- is 3.7). A student's work is rated in accordance with the following definitions:
| Four Point Grading Scale | |
|---|---|
| A | 4.00 excellent performance |
| A- | 3.70 excellent performance |
| B+ | 3.30 good performance |
| B | 3.00 good performance |
| B- | 2.70 good performance |
| C+ | 2.30 adequate performance |
| C | 2.00 adequate performance |
| C- | 1.70 adequate performance |
| D+ | 1.30 marginal performance |
| D | 1.00 marginal performance |
| D- | 0.70 marginal performance |
| F | 0.00 unacceptable performance |
| X | 0.00 did not attend or stopped attending, no basis for grade |
Courses in which any A, A-, B+, B, B-, C+ or C grade is earned are always acceptable toward an undergraduate program and graduation requirements unless specifically excluded for a particular course, program or degree. Courses in which a C-, D+, D or D- grade is earned are acceptable towards graduation requirements. No credits are awarded for any course in which an F or X grade is earned. A grade of C+, C, C-, D+, D, D-, F, or X is considered failing for students pursuing graduate level programs or degrees.
