OET score calculator

Type your Reading or Listening marks out of 42 to see roughly what OET score and grade they would be, and how many more correct answers you need for Grade B.

In short

  • About 30 of 42 correct is usually Grade B (350).
  • Near the B line, each extra mark adds roughly 10 to 15 points on our estimate.
  • Writing and Speaking aren't marked out of 42, so they need a marked letter or role-play instead.

What about Writing and Speaking?

They aren't marked out of 42, so no calculator can convert them. Trained assessors grade your letter on six criteria and your role-plays on nine. The quickest way to know where you stand is to have a letter or a role-play marked on the same criteria.

OET score questions

Is 30 out of 42 a Grade B in OET?

Usually, yes. OET says Grade B (350) in Reading and Listening normally needs about 30 of 42 correct. The exact boundary moves a little with each test version, because some versions are slightly harder than others, so treat 30 as a guide rather than a guarantee.

How is the OET score worked out?

Reading and Listening are marked out of 42 and the marks are converted to a score from 0 to 500, in steps of 10. Writing and Speaking are graded by trained assessors against set criteria and reported on the same 0 to 500 scale. Each sub-test gets its own score and grade; they are never added together or averaged.

What OET score do I need for the NMC or GMC?

The NMC asks nurses and midwives for at least Grade B (350) in Reading, Listening and Speaking, and at least Grade C+ (300) in Writing. The GMC asks doctors for at least Grade B in all four sub-tests. Both change their rules from time to time, so check nmc.org.uk or gmc-uk.org before you book.

How accurate is this calculator?

It gives an estimate. OET does not publish its exact conversion, so the calculator uses the figures OET does state (about 30 of 42 for Grade B) and a straight line either side. It is a good guide to where you are, but only your Statement of Results is official.
