The results announced by the Assembly's Education Secretary Rosemary Butler this week show that the proportion reaching level 4 (the expected standard) rose to 68 per cent in English, up by four points on last year, and 67 per cent in maths, a six-point increase.
In science, 77 per cent reached level 4, an eight-point rise, but the Welsh language results failed to improve, remaining at 65 per cent.
These results puts Welsh schools within sight of the Assembly's 2002 target - that between 70 and 80 per cent of the principality's 11-year-olds reach level 4 in all four subjects.
The country's 14-year-olds did not, however, do so well and registered no improvement on last year. In one subject, English, the proportion reaching level 5 fell by 1 percentage point.
