The education ministry is considering introducing achievement tests for high school students to help them acquire necessary knowledge and skills, officials said Friday.

A panel of the Central Council for Education plans to incorporate the idea into an interim report that may be drawn up in January, the officials said.

The ministry says the tests will only be for students or schools willing to participate in them and that they won't be linked with university entrance examinations, the officials said.

However, the specifics of the tests, including the format and when they may be introduced, remain unclear.

The ministry is also considering conducting separate common tests for technical and other specialized high school students, according to the sources.
