Queensland has pulled out of the online NAPLAN pilot after a series of glitches.

Over 100 Queensland schools were lined up to take part in next month's online national literacy and numeracy test, but Education Minister Kate Jones has now department to pull schools out.

Ms Jones says the test was riddled with issues that she felt would disadvantage kids, including one example where a question on the numeracy test remained on the screen, obscuring other questions.

Also, the tests are marked automatically, which means students are not tested on their work.

“I'm not going to put one student at a disadvantage because the online tool isn't working properly,” she said.

“I think it's much safer and wiser to delay the implementation of NAPLAN online this year.

“We need to be sure that the system is fully ready, so parents and teachers don't lose faith in the program overall.

“We don't want students to be halfway through the tests and having technical problems.”

Ms Jones says she will discuss the issue at a meeting of Commonwealth and state education ministers in Hobart.
