A popular English-proficiency test that was canceled nationwide Friday due to a problem with testing booklets has been tentatively rescheduled for July 8, the exam organizer said Saturday.

The Japan branch of Council Exchanges, which organizes the Test of English as a Foreign Language (TOEFL) in the country, will hold a makeup test as early as July 8 to help those who need test results soon to apply for foreign universities.

The TOEFL program provides English-proficiency testing services for non-native speakers planning to study in the United States, Canada or other countries where English is used in an academic environment.

The TOEFL exam is offered once a month in Japan. As the deadline for applying for the next test, scheduled for July 15, has already passed, the council decided to schedule a retest. It aims to return results to test-takers as quickly as possible.

It will also issue a certificate for those applying to foreign universities and scholarship programs to verify the makeup test results.

Friday’s test, which kicked off at 1 p.m. at 35 locations across Japan, was quickly called off after some examinees complained that their question booklets did not seem compatible with the cassette tape being played during the listening and comprehension section.

The council discovered that the wrong booklet had been distributed to about half of some 7,000 people who sat for the exam. Test-takers in Hong Kong and South Korea were also affected, according to the Educational Testing Service, a U.S. nonprofit group organization conducts the test.

The ETS suspects computer trouble in sorting the booklets caused the error and is currently investigating the cause, the council said.

The council said Friday’s TOEFL exam was the first in Japan to be called off.

Roughly 10,000 people each month take the multiple-choice exam, which consists of three sections — listening and comprehension; structure and expression; and reading and comprehension.
