Do IB classes give college credit? Yes, generally -- but "the bar is higher than AP" undersells how differently each school actually sets that bar. Here's what a handful of real schools actually require, not just the generic "HL usually needs a 5" range.
The real per-school bar, from generous to strict
- Duke grants a limited amount of elective credit for HL scores of 6 or higher in some subjects -- how much depends on departmental recommendation, up to two course credits per exam.
- Yale takes the position that a subject requiring a 5 on the equivalent AP exam typically requires a 6 or 7 on the corresponding IB HL exam -- a real, named-out gap between the two programs at the same school, not a rounding difference.
- Princeton grants its own internally-named "Advanced Placement" status (not to be confused with the College Board's AP program) for HL scores of 6 or 7.
- Harvard sets its highest bar at the highest stakes: scoring 7s on at least three HL exams makes you eligible for Harvard's Advanced Standing Program -- the option that can shorten your time to degree, not just place you into a higher course. A 5 or 6 on an HL exam typically doesn't reach this threshold at all.
Standard Level almost never counts, anywhere
This holds across every school in this dataset: Standard Level (SL) exams are rarely accepted for credit at any school, regardless of how generous that school is with HL scores. This is true even though the American Council on Education formally recommends colleges award credit for SL scores of 4 or higher -- a recommendation our main piece on AP/IB credit mechanics already covers, and one that most schools simply don't follow in practice, HL policy or not.
What this means for you
- Don't apply an AP mental model to IB scores at the same school -- Yale is the clearest example: a 5 clears the bar on the AP side, but the equivalent IB subject can require a 6 or 7 for the same outcome.
- If Harvard's Advanced Standing Program (or an equivalent early-graduation track elsewhere) matters to your plans, check the exact score threshold now -- Harvard's is specifically 7s on three or more HL exams, not just "high scores generally."
- Standard Level credit is close to a lost cause almost everywhere -- if shortening your degree or saving tuition is the goal, HL exams are where that has to come from, not SL.
- This is one piece of the larger credit-transfer picture -- see the full mechanics of how AP and IB credit actually transfers for the credit-vs-placement-vs-nothing framework this fits into, and can AP or IB credit actually let you graduate early for what a high enough score can actually buy you.
