Swedish students take part in national curriculum tests in years three, five and nine, and these are usually marked by their own teachers. A new report by the Swedish National Agency for Education shows however that when another teacher re-marked the papers, the results ended up different in 49 percent of cases, leading them to question whether teachers' knowledge about pupils could be influencing their markings.
According to news agency TT, minister Björklund is now considering making the tests anonymous to combat the problem. The government will present new proposals in the Autumn.
Some teachers say that will not solve the problem though, as in smaller schools many teachers get to know pupil's handwriting.
