The number of children leaving primary school in England with a good grasp of reading, writing and maths has increased again, government data shows.
Some 67% of 11-year-olds gained the expected level, Level 4, in all of these subjects in national curriculum tests, known as Sats.
Last year 64% of primary pupils left school having reached this level.
But one in three youngsters still failed to achieve the level expected of them in all three subjects.
This means that nearly 183,000 pupils left school without a good grasp of reading, writing and maths this summer.
