Below is a comprehensive, grade-appropriate list of subject matter and specific topics/skills a typical U.S. 9th-grade (age ~13–15) student should master. I group items into core academic subjects first, then common electives and life skills. If you want this mapped to a particular state standard, textbook, or a semester-by-semester scope-and-sequence, tell me and I’ll tailor it.
