The number of primary schools failing to give pupils a good grounding in the three Rs has halved in the space of a year, official figures suggest.
In total, 521 schools in England are below the Government's floor target for primaries, according to an analysis of data used to create new primary school league tables.
Last year, 1,310 schools were below the threshold.
The results show that schools have "responded to the challenge" that was given to them, the Department for Education (DfE) said.
