The passing grade in middle school can vary depending on the state and school district. For example, in North Carolina, anything less than a 60% mark is considered a failing score. However, if a new law is approved, the failure grade would be anything less than 40% . In general, a passing grade in the US is typically a D, which is between 59% and 69% .

Its important to note that grading scales can differ between elementary, middle, and high schools, as well as between school districts. For instance, the State Board of Education in North Carolina approved a 10-point range for each letter grade in high schools, with a failing grade being anything below 60% . However, elementary and middle schools in North Carolina can still use grading scales set by their district school boards.

Therefore, its best to check with the specific school or school district to determine what constitutes a passing grade in middle school.
