“School performance tables are not an accurate or reliable indicator of school effectiveness. The Progress 8 measure that is used to compile these tables is inherently flawed. Using the grade a child achieved in primary school in two subjects is not a safe starting point against which to assess their attainment five years later. Nor does it take into account all the additional problems and factors that affect pupil attainment.
“The tables can also disadvantage schools in economically and socially deprived areas. Many good schools fall in the bottom half of the tables simply because they serve poorer communities. There is a well-established link between child poverty and academic attainment, yet performance tables fail to reflect the hard work that schools put in to try and compensate for the poverty that many children experience.
“Damian Hinds must look at the evidence, stop this inaccurate and misleading use of data and move towards accountability that gives a true picture of the work and attainment of schools.”
