Duolingo for a UK Cybersecurity Master's: Admission vs Visa

Can you skip IELTS and use the Duolingo English Test (DET) for a UK cybersecurity master’s? There are two separate questions: whether the university accepts it for admission, and whether your Student visa accepts it as proof of English. The answers can differ, and mixing them up is one of the most expensive mistakes an applicant can make.

Table

The two requirements

A university sets its own admission requirement and can accept the tests it chooses. The Home Office sets a separate English requirement for the Student visa. The guides we read, which reproduce GOV.UK’s Student visa guidance, say this visa requirement is CEFR level B2 for degree-level study and B1 below degree level, and that the DET is not on the approved list of Secure English Language Tests (SELTs).

What that means in practice

SituationWhat the guidance says
A university accepts the DET for admissionThat affects your offer, not your visa. A test accepted for admission is not automatically a SELT
Degree-level or higher course, and the university assesses your English itselfGuides quoting GOV.UK say your higher education provider can assess your English itself, confirm it on your CAS and may ask for a different test, which must still be equivalent to B2. In that case no separate SELT is needed
The university does not assess your English itself, and you have no qualifying degreeYou need a SELT from an approved provider, such as IELTS for UKVI, PTE Academic UKVI or a LanguageCert SELT
A course below degree level, such as a pre-sessional or foundation courseA SELT is needed; the self-assessment route is limited to degree level or above
A degree taught in English and awarded by a UK institutionThe guides say this can meet the requirement with the degree certificate, without a test

What your CAS has to say

The route that matters for a master’s is the university assessing your English itself. The guides say the sponsor records on the CAS how it assessed your English, or that a specific SELT is required. So the practical test is simple: before you rely on a DET score, ask the university in writing whether it will assess your English itself, and whether the CAS will say so.

Which cybersecurity masters accept it?

We did not verify DET policy for the universities in our guides, so we name none. Where we read English requirements on university pages, York, Warwick and Lancaster ask for IELTS 6.5 with at least 6.0 in each component. Policies on alternative tests change, so ask each university and keep the reply. Our entry requirements guide lists the degree and English lines we could read.

A practical way to avoid the trap

  1. Ask admissions whether the DET is accepted for your course and what score is needed.
  2. Ask whether the university will assess your English itself for the visa, and whether the CAS will confirm it.
  3. If the answer to the second question is no, book a SELT early, because results are only usable for a limited period; the guides we read say two years from the test date.
  4. Keep all written confirmations with your application records, and check the timeline against the funds rule in our calculator.

Correction, November 2026

An earlier version of this guide listed named universities as accepting the DET, said more than 130 universities accept it, and described how most established universities assess English themselves. We could not verify the named universities or the count from the sources we read, so they were removed. The central distinction between admission and visa requirements is unchanged.

What we could not confirm

We could not open GOV.UK’s Student visa English page in this session, so the guidance above comes from guides that quote it. Please read the official page before you rely on it. We also did not verify the DET scores any university requires.
