What is the grade system for middle school?

The grade system for middle school typically includes grades 6 through 8, with students generally ranging from ages 11 to 14. Assessment is usually based on letter grades (A, B, C, D, F), with A being the highest and F indicating failure. Many schools also use a grade point average (GPA) system, where each letter corresponds to a numerical value, often on a 4.0 scale. Additionally, some schools may incorporate standards-based grading or other assessment methods to evaluate student progress.
