What is a passing grade in middle school California?

There's no single "passing grade" defined statewide for all middle schools in California. Individual school districts and even individual schools may set their own passing grades, though they generally fall within the range of 67% to 70%. However, a grade of "D" is generally considered passing, while a "C" or higher indicates satisfactory performance. It's best to check your specific school's grading policy or your student's handbook for the definitive answer.
