The government decided Friday to put off the planned introduction of private-sector English proficiency tests as part of standardized university entrance exams next April, the education minister said a week after making a gaffe on the matter.

"We cannot recommend the current system to students with confidence," education minister Koichi Hagiuda said at a news conference.

He said the ministry will review the system for over a year, including whether private-sector tests should be used at all, and aim to introduce a new system for around the 2024 school year.
