This table lists the 200 primary schools with the lowest Sats results in England in 2014.
At these schools 45% or fewer Year 6 children achieved at least a Level 4 in reading, writing and maths.
The average point score - the average number of points scored per pupil in the tests - is used as a tie break.
The list does not include schools with fewer than ten pupils in Year 6.
(However, when the table was first published, it inadvertently only excluded schools with fewer then ten pupils in the whole school. It was updated on 16 December)
