Ofsted faces fresh calls to halt graded school inspections in England

ENGLAND, 10 OCTOBER 2026 —

The Association of School and College Leaders (ASCL) has formally called for an immediate halt to graded inspections in England, marking a significant escalation in the ongoing dispute between education unions and the state inspectorate.

This development follows a similar stance taken by the National Association of Head Teachers (NAHT), which previously warned that the current system posed a "risk to life" for school leaders if urgent changes were not implemented.

The ASCL’s announcement represents a critical turning point in the debate over school accountability in England. By passing a motion of no confidence in the ability of Ofsted’s leadership to address the damage caused by the new system, the union has signaled that diplomatic negotiations have failed. Pepe Di’Iasio, the general secretary of ASCL, stated that the union did not take this step "lightly," emphasizing that Ofsted’s "warm words about recognising wellbeing pressures...

have not been matched by the action necessary." He further noted that "negotiation [had] hit a brick wall," indicating that the relationship between the regulator and the professional body has deteriorated to a point where industrial action is now being considered as a viable next step.

The core of the dispute centers on the report card system introduced by Ofsted last November. This framework replaced the previous one or two-word judgements with a multi-faceted grading system designed to assess schools across several areas rather than relying on a single overall grade.

The shift was precipitated by the death of head teacher Ruth Perry, who took her own life after her school was downgraded from "outstanding" to "inadequate." An inquest ruled in January 2023 that an Ofsted inspection had contributed to her death, a finding that triggered a fundamental review of how the inspectorate assesses educational institutions.

Despite the intent to create a more nuanced evaluation process, the new system has drawn sharp criticism from frontline educators. The NAHT, which raised concerns just under a year ago, reported that testimonies from its members suggested some school leaders had faced "intolerable" pressure. These leaders described themselves as "overwhelmed" and "anxious" under the new regime.

The union warned that without immediate reforms, the system could continue to pose a severe threat to the mental health and safety of those leading schools. The ASCL has now aligned itself with these warnings, arguing that the current structure is causing significant harm to the workforce.

In response to the union’s motion, Ofsted’s chief inspector, Sir Martyn Oliver, defended the inspectorate’s trajectory on Friday. He cited an independent survey of education providers, stating that the data showed Ofsted was "on the right track" with its inspections.

Sir Martyn acknowledged the difficulties facing the sector, saying, "I know that workload and wellbeing in education continue to be challenging, and I don’t take that lightly." He added that the organization would "keep listening to feedback from professionals and parents alike as we continue to improve what we do," suggesting a commitment to iterative improvement rather than a complete overhaul of the current framework.

The independent report commissioned by Ofsted to evaluate the new framework provides a mixed picture of the system’s impact. The interim report, based on focus groups and nearly 700 responses from school, college, and early years leaders who completed surveys following inspections this year, concluded that leaders were "generally positive" about their inspection experience.

It noted that the new process was "more collaborative and accounts for context better than previous inspections." However, the report also highlighted significant concerns regarding staff welfare, finding that nearly half (48%) of the school leaders who responded said their staff’s mental wellbeing had been negatively affected "a fair amount" or "a lot" by a recent inspection.

This data presents a complex challenge for policymakers. While the structural changes appear to have improved the collaborative nature of inspections, the human cost remains high. The ASCL has called on the government to pause inspections entirely to allow for a comprehensive review of the system.

The union stated it would survey its members on whether to hold an informal ballot on industrial action if no changes are made, raising the prospect of strike action in the education sector. This threat of industrial disruption adds a new layer of urgency to the negotiations, as a halt to inspections could have broader implications for school accountability and public confidence in the education system.

The Department for Education (DfE) has also weighed in on the matter, emphasizing the importance of balance in the inspection process.

Ministers stated they were "working with Ofsted and school leaders to ensure accountability is fair, proportionate and focused on helping every school get better." The DfE added that "inspection and accountability are vital, but they must reflect the reality of what is happening in schools, recognise the context they are working in, and support improvement rather than add to the pressures they already face." This statement underscores the government’s attempt to position itself as a mediator, seeking to uphold the necessity of oversight while acknowledging the need for a more supportive approach.

Ofsted itself has acknowledged the ongoing challenges, with a spokesperson stating that the organization had "worked hard to reduce the pressure of inspection in recent years, but we know workload and wellbeing remain a challenge." The spokesperson added, "We are working with the Department for Education on this and we will keep listening to feedback from professionals as we continue to improve what we do." This response mirrors Sir Martyn Oliver’s comments, reinforcing the inspectorate’s stance that it is actively engaged in the process of refinement, even as unions argue that the current pace of change is insufficient to address the immediate welfare crisis.

The situation highlights a deepening divide between the regulatory framework and the lived experience of school leaders. While the independent survey suggests that the new system is perceived as more collaborative and context-aware, the high percentage of leaders reporting negative impacts on staff mental wellbeing indicates that the transition has not been smooth.

The ASCL’s motion of no confidence serves as a formal rebuke of Ofsted’s leadership, suggesting that the trust required for effective collaboration has been eroded. The union’s call for a pause in inspections is a direct challenge to the status quo, demanding that the government and Ofsted prioritize the welfare of educators over the continuity of the inspection cycle.

As the full report from the independent evaluation is due to be published next year, the interim findings have already fueled the debate. The 48% figure regarding negative impacts on staff mental wellbeing is a stark statistic that unions are likely to use in their arguments for immediate action.

The prospect of an informal ballot on industrial action by the ASCL signals that the dispute is moving from the realm of policy discussion to potential operational disruption. For the Department for Education, the pressure is mounting to demonstrate that it can deliver on its promise of fair and proportionate accountability without further exacerbating the strain on the education workforce.

The case of Ruth Perry remains a central reference point in this controversy, serving as a tragic reminder of the potential consequences of high-stakes inspections. The inquest’s ruling that the inspection contributed to her death has cast a long shadow over Ofsted’s practices, making the current dispute not just about administrative efficiency but about the safety and dignity of school leaders.

The ASCL’s description of the system as an "overbearing mess" reflects a sentiment that the new framework, despite its intended improvements, has failed to alleviate the pressure on those at the front line of education.

The next steps in this dispute will likely be determined by the outcome of the ASCL’s member survey and the government’s response to the call for a pause in inspections. If the union proceeds with a ballot on industrial action, it could mark a significant escalation in labor relations within the English education sector.

The Department for Education’s commitment to working with Ofsted and school leaders will be tested as it seeks to navigate the competing demands of accountability and welfare. The situation underscores the difficulty of balancing rigorous oversight with the human element of education, a challenge that has yet to be fully resolved despite the introduction of the new report card system.

In the broader context of regional and international education policy, the developments in England offer a case study in the tensions inherent in high-stakes accountability systems. The response of unions and the government will be closely watched by observers in other jurisdictions who are grappling with similar issues of teacher welfare and inspection pressure.

The ASCL’s stance, backed by the earlier warnings from the NAHT, suggests a unified front among head teachers’ unions in demanding systemic change. The outcome of this dispute will have lasting implications for the relationship between regulators and educators in England, potentially reshaping how inspections are conducted and perceived in the years to come.

The story concludes with the ASCL’s clear demand for a pause in inspections and a review of the system, a position that has now been formally adopted by the union’s membership. The threat of industrial action looms over the sector, creating a sense of urgency for the Department for Education and Ofsted to engage in meaningful dialogue.

The independent survey’s findings, while showing some positives, also highlight the significant challenges that remain, particularly regarding staff mental wellbeing. As the full report is awaited, the interim data and the unions’ actions provide a clear indication that the current system is under intense scrutiny and that the status quo is no longer tenable for many in the education profession.

The next phase of this dispute will likely be defined by the government’s willingness to act on the unions’ demands and the potential for industrial unrest if those demands are not met.
