Teaching in classes grouped by ability does not hamper progress of less able pupils, study finds

Research on maths teaching in English secondary schools upends decades of debate over mixed-ability education

Teaching pupils in classes grouped by ability improves the results of high-flyers but does not affect the progress of less able children, according to a study that upends decades of debate over mixed-ability education.

The research by University College London's Institute of Education found that secondary school pupils in England with previously strong maths performances made slower progress in mixed-attainment classes than when they were taught alongside children with similarly high ability.
