Covering the gaps: Teaching assistants, lesson cover, workforce pressure and displaced support in mainstream schools

Abstract This article examines the deployment of teaching assistants (TAs) to cover classes in place of teachers in mainstream schools. Drawing on survey data from over 8000 support staff in England, the analysis focuses on the scale, character, reported reasons and consequences of TA‐led cover. The article conceptualises lesson cover as a site through which wider workforce pressures are absorbed and redistributed within schools. It uses the concept of ‘organisational triage’ to describe how schools allocate limited staffing capacity to immediate and visible demands under constrained conditions. The findings suggest that TA‐led cover is common and often substantial: two‐thirds of TAs reported covering classes as part of their role, and among those who covered on their most recent working day, the estimated mean duration was 2 h 41 min. Reported reasons for cover included planned release, short‐term absence and wider staffing pressures, including unfilled vacancies and shortages of usual cover staff. The analysis also shows that when TAs were deployed to cover classes, pupils missed out on classroom support, one‐to‐one support linked to an Education, Health and Care Plan, curriculum interventions and therapy sessions. The article argues that while TA‐led cover can address the immediate problem of an uncovered class, it can displace support elsewhere. The article concludes that lesson cover should be understood as both a workforce issue and a provision issue, with implications for school workforce policy, TA deployment and inclusive mainstream education.
