Girls are still outperforming boys in all subjects at the age of seven.
But while more girls reach the expected level in reading, writing and maths, boys are more likely to reach the highest levels in maths and science.
This week's key stage 1 results show that 85 per cent of children reached the expected level 2 in reading in 2005, 82 per cent in writing and 91 per cent in maths.
In reading, 32 per cent of girls reached the higher level 3, compared with 22 per cent of boys; 20 per cent of girls reached this level in writing, compared with 10 per cent of boys.
In maths, though, one in four boys reached level 3, compared with one in five girls.
In science, just over one in four boys reached level 3, compared with just under one in four girls.
This year, for the first time, teacher assessments were reported, rather than test results.
The teacher assessments are based on test results, but teachers were given freedom over when to run the tests and whether to use this year's papers or last year's.
But early indications from the National Assessment Agency show that most teachers did not change their way of working.
The reading and writing results this year show no change from last year, when a quarter of schools were asked to report teacher assessments and the rest still reported national test results.
