A recent study conducted by University College London’s Institute of Education reveals that grouping students by ability in mathematics classes significantly benefits high-achieving pupils while not hindering the progress of lower-achieving students. The research analyzed data from 28 mixed-ability schools and 69 schools utilizing ability setting, focusing on year 7 and 8 pupils aged 11 to 13 in England. Findings indicated that high achievers in mixed-ability classes made an average of two months' less progress compared to their peers in ability-based settings. Conversely, low-attaining students showed little difference in progress between the two types of classes. The study also highlighted that mixed-ability schools, while having a smaller achievement gap, did not provide adequate challenges for high achievers. Experts like John Jerrim and Becky Francis emphasized the importance of this research in reshaping educational strategies, particularly in mathematics, while also stressing the need for qualified teachers to effectively implement ability grouping.
