The Department for Education has released figures revealing the best- and worst-performing academy trusts in England.
They include only multi-academy trusts that have at least three schools that have been with them for at least three years.
The MAT league tables for secondary schools use 2018 Progress 8 scores to compare the performance of academy trusts at GCSEs.
The DfE data puts multi-academy trusts into five bands: well above average, above average, average, below average and well below average.
