Commenting on new research funded by the National Foundation for Educational Research, Daniel Kebede, general secretary of the National Education Union, said:
"This is a timely and insightful report. It reminds us that operating schools like a market, around competition, ranking and naming and shaming, leads to inequality and unsustainable pressure on schools with inclusive intakes.
"Without proper resources and a focus on support and collaboration, rather than high-stakes inspection, the transition to better outcomes won’t succeed.
"The principles behind the proposed reforms are well-intentioned, but not feasible if funding and workforce constraints remain. A reduction in class sizes and boost in specialist expertise is crucial for building better outcomes for children with SEND.
"This report shows there is a clear case for a stronger role for local authority-controlled admissions, with clear oversight to ensure that placement decisions are made fairly and transparently."
