Psychology conversion MSc or a second undergraduate degree: the BPS accredits both, and both end in the same eligibility

If your first degree is in something else and you want to become a psychologist in the UK, the two products on sale are a one-year accredited conversion course and a three- or four-year accredited undergraduate psychology degree. The British Psychological Society treats them as producing the same thing.

Its accreditation page says so in one sentence:

“if you graduate from a BPS accredited undergraduate degree or postgraduate conversion course, you will be eligible for Graduate Basis for Chartered Membership (GBC) of the society.”

One qualification, two products, and no ranking between them from the accreditor. The BPS is explicit that it will not rank: “The British Psychological Society is unable to recommend one accredited programme over another, or likewise comment on the differences or strengths of the courses by way of comparison.”

So the decision is not about which one the BPS prefers. It is about entry conditions, length, and money.

What the BPS says a conversion course is

From the same page, verbatim:

“Graduates who haven’t taken an accredited programme in psychology may undertake a conversion course. Conversion courses provide an opportunity for graduates to build on their first-degree qualification to become eligible for the Society’s Graduate Basis for Chartered Membership.”

“The course will usually consist of at least one full year (approximately 45 weeks full-time, or its part-time equivalent) and typically comprise either 120 or 180 credits.”

The credit total is not a detail. It changes who is allowed in.

180-credit conversion courses. “Applicants to conversion programmes must normally have a degree at any level which has not been accredited by the Society (whether in psychology or another subject). For conversion programmes comprising 180 credits, this is the only entry requirement set by the Society, although individual providers may set other requirements that they expect their applicants to meet.”

120-credit conversion courses. “For awards comprising only 120 credits, applicants will need to have previously studied the equivalent of at least 60 credits of psychology at the undergraduate level (level 4 or above; level 7 in Scotland). If you haven’t done 60 credits or more of psychology study, you can usually do a bridging or access course (often a certificate in psychology) first.”

That is the first real fork. If you have never studied psychology, a 180-credit conversion course is open to you on the Society’s rules; a 120-credit one may not be, and you may be looking at a bridging certificate first — which adds time and cost that the conversion course’s own fee page will not show you.

The conditions that apply to both routes

The BPS attaches the same three conditions to GBC whichever product you buy:

“in order to gain eligibility for the GBC, you need to achieve an accredited award, follow any specified pathway detailed on the results page of the search, and gain a 2:2 or above if you started after September 2006. You must also pass the psychology project in order to be eligible for the GBC.”

Three things worth pulling out of that sentence.

“Follow any specified pathway.” Some accredited degrees are only accredited along particular routes through them — particular option choices, particular joint-honours combinations. The BPS points you at the register’s own results page for the pathway condition attached to your programme. Choosing modules freely on an accredited degree is not automatically safe.

“Pass the psychology project.” A pass in the degree overall is not sufficient. The empirical project is a named condition.

“An accredited award.” Accredited for your intake year — the BPS says elsewhere on the same page, “you need to check whether your degree was accredited for your intake year.” We deal with that separately, because it is the single most common way people lose the GBC they thought they had bought.

Length and money, at one university

Anglia Ruskin University runs both products and publishes both fee lines, which makes it the cleanest available comparison. Figures below are ARU’s published 2026/27 fees, read on 3 September 2026.

	MSc Psychology (Conversion)	BSc (Hons) Psychology
Length ARU publishes	“1 year full-time” (also 2 years part-time; 16 months full-time for January starts)	“Duration 3 years”
International fee	£19,500 per year	£18,400 per year
UK fee	£10,300 per year	£9,790 per year
Total at published international rate	£19,500	£55,200 over three years
BPS outcome ARU states	“It provides you with Graduate Basis for Chartered Membership of the BPS”	“Achieve a second-class honours degree or above, and you’ll be eligible for graduate chartered membership of the British Psychological Society”

Nearly three times the tuition, and two extra years of living costs, for the same line on the BPS register. ARU’s own conversion page frames the entry condition the way the BPS does: “No psychology degree? No problem. We welcome all students to this conversion course, whether you’ve studied psychology before or you’re new to the field.”

The gap is not an ARU quirk. The University of Glasgow publishes £33,210 as the International & EU full-time fee for its Psychological Studies (conversion) MSc in 2026-27 — one year — against undergraduate psychology at Glasgow being, in the university’s own listing, a four-year degree, because Scottish honours degrees run to four years.

The case where a second undergraduate degree is not an option at all

If you already hold an accredited psychology degree, you are not a candidate for either product. Glasgow states the position bluntly in its conversion entry requirements:

“Applicants who have completed a BPS Accredited Undergraduate (Honours) Psychology programme in the UK will be over-qualified for this programme.”

And if your psychology degree was awarded outside the UK, neither product is automatically your answer. The BPS says: “Although the society began accrediting UK awards delivered outside of the UK in 2014/15, it doesn’t currently accredit international degrees.” An overseas psychology graduate applies individually: “All overseas applications are assessed on the individual merit of the qualifications received.” Only after that assessment does the BPS say what it says next — “If you’re not eligible, then you may need to complete an accredited conversion programme.” Paying for a second undergraduate degree before that individual assessment has been done is buying a remedy for a shortfall nobody has measured.

Why anyone still chooses the long route

Three honest reasons, none of them about accreditation.

Prior study. If you have no psychology credits and the conversion courses you want are 120-credit awards, you need the 60 credits first. A bridging certificate plus a 120-credit MSc may end up longer and dearer than it looks on the MSc’s own page.

Intensity. ARU describes its conversion MSc as a one-year intensive route; a three- or four-year undergraduate degree spreads the same core content over three or four times the calendar. The BPS requires the same coverage from both.

Entry grades. Conversion providers set their own admissions bars on top of the BPS minimum. Glasgow’s is “2.1 Hons (or non-UK equivalent) in any subject.” An applicant whose first degree is below that at the providers they can reach may find the undergraduate route is the one that is actually open.

What we could not verify

A complete, current list of which accredited conversion courses are 120 credits and which are 180. The BPS states the two sizes and the different entry rules attached to them, but the credit total is not a field we could read on the register’s programme records. Ask the provider in writing which it is before you assume you meet the Society’s entry rule.

Living costs, deposit terms and non-tuition charges. Providers publish these separately and inconsistently; Glasgow, for example, requires a £2,000 deposit from International and EU applicants at offer stage. We list tuition only, and tuition is not the total.

Anything about visas. Whether a course can be studied on any particular immigration route is a matter for the provider’s own statement and for gov.uk. We do not give immigration advice and we do not publish immigration conclusions.

What to do

1. Get your intake year’s accreditation status in writing before you accept an offer — for whichever product you choose. The BPS’s own instruction is to check accreditation “for your intake year”.
2. Ask the provider the credit total of the conversion award, and whether the Society’s 60-credit prior-study rule applies to you.
3. Ask what the specified pathway is, if any, and get the answer in writing. It is a named GBC condition.
4. If your psychology degree is from outside the UK, apply for the BPS’s individual assessment first. The Society assesses overseas qualifications on their own merits and only then tells you whether a conversion course is needed.
5. Compare total programme cost, not the annual fee. One year against three or four changes the answer more than any headline fee does.

We are not the BPS, we do not accredit programmes and we do not decide who is eligible for Graduate Basis for Chartered Membership. The Society does, against its own published standards. What this page does is set out, from its own words and from providers’ own fee pages, what the two products actually cost and what conditions each one carries.
