Recent reports by the Education Policy Institute thinktank and the Fair Education Alliance have highlighted that, despite efforts of schools and policy-makers, the attainment gap at KS4 is actually widening. For educators driven by a desire to help every student do the best they can, this discrepancy is a tragedy, especially considering that students with lower prior attainment tend to have the greatest opportunity to make gains. The circumstances seem to prevent this opportunity from being exploited.
