The Best IBDP Subject Combinations for Psychology

Planning to study Psychology beyond IBDP? A good combination of subjects can equip you with the scientific, analytical, research and communication skills required at university for Psychology.

The ideal subject combination to study at the IB Diploma Programme in Psychology is not set. The entry requirements for universities vary, students are advised to consult entry requirements of the universities they are interested in before confirming their options for HL & SL.

The IB suggests to take subjects into account in light of future university and career aspirations.

Which IB subjects are best for Psychology?

Many students aiming for study of Psychology at University will find a combination of Psychology HL, Biology HL and either Mathematics or another analytical subject at HL to be a good choice.

This is where the integration of psychology theory, knowledge and quantitative/analytical skills come together. The IB Psychology course in the present focuses on human behaviour and cognition is explored using psychological research, including evidence, critical thinking and research methodologies.

But not all universities require Psychology HL in their degree program in Psychology.

Is Psychology HL Necessary for a Psychology Degree

Not always. Psychology may be considered acceptable preparation for some universities, and others have specific requirements for academic preparation.

The IB Psychology course is not about preparing students to be psychologists, but rather encouraging them to become psychologically literate. Pupils learn about concepts, research techniques, evidence and varying viewpoints about human behaviour.

Hence, select Psychology HL because it is of interest to you and your strengths, not just because it is required.

Why Take Biology, HL?

It can be very advantageous for students who are studying the scientific aspects of Psychology to take Biology HL.

Can give appropriate bases for topics related to the brain, nervous system, human development and biological factors of behaviour. It is also useful to students who are thinking about studying Psychology with related studies such as neuroscience or health.

Is Mathematics helpful for Psychology?

Yes. It is a scientific study that requires research, data interpretation and evaluating evidence. Thus, Mathematics can be used to supplement the study of Psychology to build quantitative and analytical skills.

There are some degrees in Psychology that focus more on research than others, and having solid mathematical skills may be especially advantageous for students seeking these programs.
