A groundbreaking study by the Institute of Education at University College London has cast new light on the effectiveness of ability grouping in mathematics classes, suggesting that such an approach may enhance the learning outcomes for high-achieving students without negatively impacting those of lower-achieving pupils. This research, supported by the Education Endowment Foundation (EEF), could reshape the ongoing debate surrounding mixed-ability education, which has persisted for decades.

Findings on Academic Progress

The study’s findings reveal that secondary school students in England who previously excelled in mathematics experience slower progression in mixed-ability classrooms compared to their peers in ability-set classes. Specifically, high-achieving students in mixed settings made an average of two months less progress than those in classes grouped by ability. The overall progress of students in mixed-ability schools was also found to lag behind that of their peers in set classes by one month.

Interestingly, the research indicated that grouping by ability does not harm the academic performance of lower-achieving or socioeconomically disadvantaged students. This challenges the prevailing belief that such an educational structure could disadvantage these groups. Professor John Jerrim, an expert in education statistics, described the study’s findings as both significant and transformative, advocating for a re-evaluation of how schools approach ability grouping.

Implications for Teacher Workload and Student Confidence

One noteworthy aspect of the research is its exploration of student self-confidence in mathematics. The analysis showed that pupils in mixed-ability settings reported lower confidence levels compared to their counterparts in ability-set classrooms. This finding raises important questions about the emotional and psychological impact of classroom configurations on students’ attitudes towards learning.

Professor Jerrim highlighted the potential benefits of ability grouping, suggesting that it may not only enhance academic outcomes for high achievers but also ease the workload for teachers. The implications of this research could lead to a shift in educational policy, particularly as it pertains to the organisation of mathematics instruction.

The Role of Educational Leaders

Becky Francis, chief executive of the Education Endowment Foundation, noted the innovative nature of the study, which directly compares the performance of students in mixed-ability classes with those in ability-set classes. She affirmed that the findings would be instrumental in guiding schools on how best to structure their mathematics programmes.

Pepe Di’Iasio, general secretary of the Association of School and College Leaders, emphasised that school leaders are best positioned to make decisions about ability grouping based on their unique contexts and the needs of their students. He pointed out that sufficient numbers of qualified mathematics teachers are essential for the success of any ability grouping strategy, as many schools currently face challenges in recruiting specialists.

Why it Matters

This research has the potential to influence educational policies across England, particularly in the realm of mathematics education. By demonstrating the benefits of ability grouping for high-achieving students while maintaining support for those who struggle, schools may be encouraged to reconsider their classroom structures. Ultimately, the findings advocate for a more tailored approach to education that recognises the diverse needs of students, potentially leading to improved outcomes for all learners.
