Higher level and standard level in the Diploma
The IB Diploma asks students to study six subjects, normally three at higher level and three at standard level, alongside the core elements of the programme. Higher level subjects are studied in greater depth and over more teaching hours than standard level ones, though both are examined and both contribute to a student's total points. The distinction is central to how the Diploma works and, as it turns out, to how universities read an IB profile.
Understanding which subjects sit at higher level and which at standard level is therefore not a minor detail. It shapes both the student's workload and the way an admissions tutor interprets their application.
Why universities focus on higher level
Universities pay particular attention to higher level subjects because they represent the deepest study in the Diploma and map most closely onto the demands of a degree. When a course has subject requirements, such as a science for engineering or medicine, universities almost always want that subject at higher level rather than standard level. Higher level performance is treated as the strongest signal of a student's readiness for a subject at degree level.
This is why the choice of higher level subjects can matter more than any other single decision in the Diploma for a university bound student. Getting the required subjects into the higher level column is often the difference between meeting and missing an entry requirement. Our note on the difference between standard and higher level explains the split in more detail.
How offers are usually written
Universities that accept the IB typically express offers as a total points score together with specific higher level grades. A common pattern is an overall points requirement plus a set of grades required in named higher level subjects, so a student sees both a global target and subject specific conditions. Standard level grades and the core points can also feed into the total, but the named conditions usually sit at higher level.
Reading an offer this way makes the priorities clear. A student needs to hit the overall points and, crucially, the specified higher level grades in the right subjects. Missing a higher level condition can matter even when the total is met, which is why higher level planning deserves early attention.
Match higher level subjects to the course, early
The single most useful step is to line up higher level subjects with the requirements of likely courses before choices are locked in. Read the entry requirements on each course page, then choose higher level subjects to meet them. Our IB hub gives background on how the Diploma is structured.
Choosing higher level subjects
Because higher level subjects carry the most weight, they should be chosen with target courses in mind. A future medic needs chemistry and usually biology at higher level, an engineer needs mathematics at the appropriate higher level and physics, and many humanities and social science courses want a relevant subject at higher level too. Where a student is unsure of their direction, keeping a balanced and strong set of higher level subjects preserves the most options.
It also helps to be realistic about workload. Higher level subjects are demanding, so a student should choose subjects they can perform strongly in, since a high grade in a required higher level subject is what universities are looking for. Overreaching across three very demanding higher level subjects can backfire if grades slip.
Standard level still counts
Standard level subjects are far from filler. They contribute to the total points that most offers require, they keep a student's education broad, and a strong standard level grade can still support an application. What differs is that standard level subjects rarely carry the named subject conditions that higher level ones do, so they play a supporting rather than a headline role in most offers.
The practical message is to take standard level subjects seriously for the points and the breadth, while recognising that the decisive subject requirements almost always land at higher level. A balanced Diploma with strong results across both levels reads best of all.
How to plan
The clearest way to plan is to work backwards from likely courses. Identify the subjects those courses require, place them at higher level, choose the remaining higher level subject to keep options open or match an interest, and then build a strong standard level set around them. Confirm the specific requirements on each course page, since they vary and can change, and revisit the plan if a student's direction shifts.
Families comparing the IB with other routes may find our A Level and IB comparison for universities useful, and our guide on moving from international school to UK university covers the application mechanics.
Frequently asked questions
Do universities care more about HL or SL?
Universities focus on higher level subjects because they represent the deepest study in the Diploma. Subject requirements are almost always set at higher level, so HL choices drive most offers.
How are IB offers usually written?
Offers typically combine an overall points target with specific grades required in named higher level subjects. Standard level and core points feed the total, but the named conditions usually sit at higher level.
Does standard level count for anything?
Yes. Standard level subjects contribute to the total points most offers require and keep a student's education broad. They simply carry the named subject conditions less often than higher level subjects.
How should I choose my HL subjects?
Work backwards from likely courses, place any required subjects at higher level, and choose subjects you can achieve strong grades in. Confirm each course's requirements before locking in choices.
