Undergraduate · LSE Psychological and Behavioural Science
LSE's BSc Psychological and Behavioural Science brings psychology and behavioural science into one degree, explored from both social science and natural science perspectives, and is accredited by the British Psychological Society. It asks for A*AA including at least one of Biology, Chemistry, Physics, Mathematics or Psychology, and a high level of numeracy. The distinct question is whether you want psychology that is applied to social questions in health, education and policy, with strong research-design and statistics training, rather than a more laboratory-led or clinically oriented psychology degree.

Taken from LSE's BSc Psychological and Behavioural Science programme page and read on 31 October 2026. For a normal 2028-entry application, made in 2027, every requirement below is last verified for the previous cycle and may change; LSE's 2028-entry requirements and dates are awaiting publication.
LSE describes an unusual combination of psychology and behavioural science, from social science and natural science perspectives, accredited by the British Psychological Society. It lasts three years.
The A-level requirement is A*AA including at least one of Biology, Chemistry, Physics, Mathematics or Psychology; the contextual offer is AAA with the same condition. The IB requirement is 39 points overall including 766 at higher level with one of those subjects at higher level.
LSE asks for GCSE English Language at B (6) or higher and Mathematics at A (7) or higher.
LSE says you should have strong scientific abilities with at least one grade A in Biology, Chemistry, Physics, Mathematics or Psychology, and looks for high levels of numeracy.
Students learn to conduct empirical research, including qualitative approaches, and take compulsory statistics and research methods courses in the first and second years.
Official sources
Read on 31 October 2026 on LSE's BSc Psychological and Behavioural Science programme page, which describes 2027 entry. LSE's general entry requirements and English-language pages, the fees pages, the contextual-offer details and the 2028-entry values were not read, and the page lists no additional admissions test or interview so none is stated and are not stated.
The programme
In the first year students take Foundations of Psychological Science, Foundations of Behavioural Science and a compulsory Statistics and Research Methods course, plus LSE100 and one unit of outside options. In the second year they take Intermediate Statistics and Research Methods and five compulsory half-unit courses: Biological Psychology, Cognitive Psychology, Developmental Psychology, Social Psychology: Individuals, Groups and Culture, and Individual Differences and Why They Matter. LSE says students learn how psychological and behavioural science theories can be applied to social issues in areas such as health and education, and graduates progress to careers in government, NGOs and the private sector.
Which psychology degree?
Avandy has guides to UCL Psychology and to Oxford's Experimental Psychology, each with different rules. Compare by course.
you want psychology and behavioural science together, applied to policy, health and education, with strong training in research design and statistics.
you prefer its scientific-methods framing. Avandy's guide records an A-level requirement of A*AA with A*A from two sciences, and a different IB pattern.
you want the Oxford tutorial and TARA route. Avandy's guide records A*AA, IB 39 with 766 at Higher Level and the TARA requirement.
Entry rules
The A-level standard is A*AA including at least one of Biology, Chemistry, Physics, Mathematics or Psychology; the contextual offer is AAA. The IB standard is 39 points overall including 766 at higher level, with one of those subjects at higher level. GCSE English Language is required at B (6) and Mathematics at A (7). LSE will consider Mathematics, Further Mathematics and an essay-writing subject. The page lists no additional admissions test. LSE's page shows 1,125 applications, an intake of 66 and a 17:1 ratio for 2025; these are historical figures, not a requirement or a prediction.
A decision framework
This is Avandy's own framework, not LSE's.
The degree stresses behavioural science and policy applications as well as the core areas of psychology.
Both years 1 and 2 include compulsory statistics and research methods courses.
At least one grade A in Biology, Chemistry, Physics, Mathematics or Psychology is expected.
Planning for 2028 entry
Applying for 2028 entry means applying in 2027, under rules LSE has not yet published for that cycle. Each item below carries one of two labels. Last verified for 2027 entry means LSE published it for the previous cycle and it may change. Awaiting publication for 2028 entry means LSE has not yet published it.
These are the best guide to what to prepare. LSE has not confirmed them for 2028 entry.
Check LSE's programme page for the 2028-entry values when they appear.
Confirm a science or Mathematics at A level, check GCSE Mathematics and read about the first-year foundations courses.
Support
Avandy provides independent academic and admissions support. It is not affiliated with the London School of Economics and Political Science or any of its colleges or departments. Preparation sits within the Avandy Trinity Advisory Model: a Strategic Admissions Consultant, a PhD-level Academic Mentor and a Subject-specific Tutor, working to the actual requirements of each course. Support here means course-fit advice and psychology and statistics mentoring; Avandy gives no scores or probabilities and does not write submitted work. No outcome is promised.
