The TOEFL iBT® Special Home Edition is the at home version of the TOEFL iBT test. It is available everywhere that TOEFL iBT testing is normally available, except Mainland China and Iran. The ability to register for the TOEFL iBT Special Home Edition is based on the country name you enter in your ETS account. If the country name matches a country where the test is available, you will see the "Special Home Edition" test as you begin registration.
In Mainland China, testing has resumed at a limited number of locations. Additional locations and dates are being added monthly as conditions permit. In Iran, the test center network is operational and resumed testing in June.
The TOEFL iBT Special Home Edition is identical in content, format, on-screen experience and scoring to the TOEFL iBT test taken at a test center. To maintain test security, it is monitored online from start to finish by artificial intelligence technology and trained human proctors from ProctorU®.
