Debate on Streaming Students Based on Ability: New Research Offers Insights
Should we ‘stream’ school students based on ability? New research suggests yes – but we need to be cautious

Recent UK research indicates that streaming students by ability, particularly in mathematics, may benefit high-achieving students without harming others. However, concerns remain about equity and the potential negative impacts on lower-achieving students, prompting a cautious approach for Australian schools considering similar practices.
- 01Streaming in UK schools showed high-achieving students made three months more progress in mathematics compared to mixed-ability settings.
- 02Students from disadvantaged backgrounds did not experience negative impacts from streaming, making similar progress regardless of grouping.
- 03Concerns persist about streaming widening achievement gaps, particularly affecting students from minority and lower socioeconomic backgrounds.
- 04Effective mixed-ability teaching involves rigorous tasks and differentiation, which were lacking in some observed classes.
- 05Australia's educational context differs from the UK, with many smaller schools unable to implement streaming.

The debate on whether to stream students based on ability continues, with new research from the United Kingdom suggesting potential benefits for high-achieving students in mathematics. The study found that students in streamed classes made three months more progress than those in mixed-ability settings, and there was no detrimental effect on students from disadvantaged backgrounds. However, concerns remain regarding the inequity of streaming, as it may exacerbate existing achievement gaps, particularly for students from minority and lower socioeconomic backgrounds. Critics argue that lower-streamed students often miss out on challenging work, leading to a cycle of low achievement and diminished self-confidence. In Australia, where streaming is common, educators are urged to approach this practice with caution, considering the different educational contexts and the importance of effective teaching methods. The findings highlight the need for ongoing evaluation of how different grouping strategies impact student learning and achievement.
