If you’re taking IB courses or enrolled in the IB Diploma Programme through your high school, you may be wondering what exam scores you’ll need to be more competitive at your schools of choice. In today’s post, we’ll be covering the IB grading scale, including what elite colleges want to see. We have a lot to review, so let’s get to it!

What is the IB Grading Scale?

First, let’s review the grading criteria for passing the overall (DP). Here’s what IB officially says about how you’ll be graded:  

“The diploma points are calculated by adding together the grades achieved from each of the six subjects and the core. Candidates receive a grade of 1-7 for each subject and up to three points for the core elements (EE and TOK). Standard level (SL) and higher level (HL) subjects are equally valued in determining the candidate’s final points. To achieve a diploma, students must earn at least 24 points and have met the conditions listed below.

The highest score that a candidate can achieve is 45 points. The maximum points of 45 is obtained from 6 (subjects) times 7 (top grade) plus 3 points from the core.”

If you’re taking individual IB courses but not pursuing a diploma, you’ll still receive a grade of 1-7 on each exam, with 7 being the highest score.

What Should My IB Score Be for Elite Colleges?

The vast majority of schools don’t actually list their range for IB DP scores. However, to get into an elite school, you want to be as close to that 45-point score as possible. Scoring above a 40—or more ideally, a 42 or higher—typically puts you into the competitive range for many elite schools. 

(Heads up: Other articles that cite exact scores for specific schools are typically just estimating.) 

If you’re not in the IB DP, you may be wondering what score you should aim for on each individual IB exam. If your goal is to earn future college credit, you’ll typically need to earn a 5, 6, or 7. However, if your goal is to maximize admissions benefits, shoot for a 6 or a 7. 

The best advice is to study hard and push for the highest score you can get. Obviously, that’s not that helpful if you’re drilling down to the nitty-gritty. If you’re sitting in the high 30s and you have a well-rounded application, you should feel positive about your accomplishments and competitive in your applications. To reassure yourself further, talk to an admissions counselor at the schools you’re applying to and get their specific take on your individual application. It’s better to start early, ask lots of questions, and study hard in order to make the best case for yourself. 

Remember: the best advice that every school has for prospective students is that test scores are taken as a part of your whole admissions package. 

How Do I Receive College Credit for My IB Exam Score?

After you matriculate at your college/university of choice, you can apply to receive credit for your IB exam score(s). This process typically entails submitting official score reports to the college’s registrar and/or relevant academic department. If course credit is granted, it will be noted on your college transcript.
