An overview of the number of pupils in each local authority who, at the end of Key Stage 4 in 2018 (provisional data) were ranked in the bottom 20% nationally according to the Attainment 8 measure, is shown in the attached tables. The figures are based on pupils in state funded schools, and the tables also show the numbers as a proportion of all state funded pupils in each local authority.
 Attainment 8 is part of the new secondary accountability system that was implemented for all schools from 2016. It measures maths (double weighted), English (double weighted), three EBacc subjects and three others (can include EBacc). Each grade achieved constitutes a point score, which is used to calculate the Attainment 8 score.
