Update: It is working again! Everyone can register.
I think the TOEFL registration system has stopped working again.
When I try to register for the TOEFL iBT Home Edition Test I get this error:
“No available slots in this time range”
others have reported this error:
“The test center and/or test date/time are no longer available”
I think it is still possible to register to take the test at a test center.
People on social media are reporting the same thing right now for the past 24 hours. I think that the same error has been reported in the past. It seems to get fixed eventually.
Yesterday I wrote about ways to improve the pre- and post-test experience for test-takers. I suppose “improve the backend” could be added to that list. It seems to be that registration for the TOEFL is quite often offline for maintenance, or offline because of a mysterious error.
Update: People on social media have indicated that it is not possible to register for a test at a test center at this time.
Update 2: Users attempting to register for the GRE get the same error.
