Two of the most popular English-language proficiency tests in Japan can no longer be used to obtain student visas to Britain after a British TV program exposed fraud in the test-taking process.

The visa ban applies to the TOEIC (Test of English for International Communication) and the TOEFL (Test of English as a Foreign Language), said Educational Testing Service, the U.S.-based company that runs the tests, last week.

The fraud, uncovered by "BBC Panorama," a BBC program, was limited to the TOEIC, but since both the TOEFL and TOEIC tests share the SELT license regime, neither test will be used in the future, ETS said.
