The lowest passing grade varies depending on the school, program, or class. However, in most colleges and universities, a D is considered the lowest passing grade. A D is any percentage between 60-69%, whereas a failure occurs below 60% . However, some schools consider a C the lowest passing grade, so the general standard is that anything below a 60% or 70% is failing, depending on the grading scale. It is important to note that different schools, programs, or classes may have different cutoff points for what they consider a passing grade. For example, some schools consider 60 percent to be the lowest passing grade, similar to common high school grading scales. Additionally, some classes may be graded on a curve, meaning your percentage grade likely won’t align with the typical letter or GPA structure. In graduate programs, it’s common for a C to be the lowest passing grade. Some colleges let you take courses for pass/no pass, rather than a letter grade. In this instance, a D is generally not passing. A passing grade is considered to be a C or above.
