US Grade Equivalents

IB DIPLOMA GRADES

IB Grades are awarded for both Higher Level (HL) and Standard Level (SL) subjects in the IB Diploma. All IB diploma courses would normally be regarded as honors courses. Universities and colleges are also encouraged to consider a student’s total points score, as well as his or her score in individual courses. For internal purposes, ISM has estimated the following approximate equivalents between IB and US high school grades:
