Results from key stage 2 assessments reveal 90,000 more children are leaving primary school with the skills necessary for their future education compared to 2010.
Provisional results from the Department for Education show four out of five (80 per cent) youngsters achieved the expected level 4 in reading, writing and maths - up from just six in ten (62 per cent) in 2009.
The highest ever proportion of pupils reached the expected level in maths, at 87 per cent - a rise of one percentage point on last year and eight percentage points on 2010.
There was a further increase in the number of youngsters reaching the expected level in grammar, punctuation and spelling tests, with 80 per cent now doing so - a rise of four percentage points on last year's figure.
Meanwhile, the proportion of children reaching the reading standard by the end of primary school remained at an all-time high of 89 per cent.
Schools minister Nick Gibb said: "A good grounding in reading, writing and maths sets a young child up for life - so I am delighted that 90,000 more children are starting secondary school with a firm grasp of the basics compared to just five years ago."
Although 14,000 more girls than boys achieved level 5 or above in reading, writing and mathematics, the gender gap at the higher level 5 narrowed to five percentage points compared with eight percentage points last year.
In sponsored academies, the percentage of pupils achieving the expected level in reading, writing and maths reached 71 per cent - a four percentage point rise on last year.
Performance levels in converter academies also continued to climb, rising from 82 per cent last year to 84 per cent in 2015.
Mr Gibb hailed the results as vindication of the government's decision to expand the academies programme into primary schools.
