From the BBC about English language exams in the UK for people wanting to enter the country as overseas students:
Director Varinder Bajarh said: “Someone else will sit the exam for you. But you will have to have your photo taken there to prove you were present.” … each of the 14 candidates had a “fake sitter” who took the spoken and written tests for them. All the real candidates had to do was wait to have their photograph taken - as proof they were there.
As an oral examiner for a proper language testing system (Cambridge University ESOL), what can I say except that I am appalled that there is no proper ID check on candidates?
