Exam board Pearson has postponed the release of key stage 2 Sats results for Year 6 pupils in England after technical glitches disrupted its marking and data systems.
The delay pushes the publication date from Tuesday, July 7, to Thursday, July 16, 2026.
This marks the first year Pearson has managed the four-year, £180 million contract with the Standards and Testing Agency.
Government and Union Reactions
The Department for Education announced it is exploring options for recourse, including financial penalties and contract cancellation, while conducting a thorough review into the operational failure.
"Something has gone badly wrong," said Paul Whiteman, General Secretary of the National Association of Head Teachers.
The union leader emphasized that schools require immediate certainty regarding the data they will receive.
"Schools must be given cast-iron assurances that the results they receive are reliable," Whiteman added.
Education Secretary Bridget Phillipson expressed frustration on behalf of the educational community regarding the sudden schedule shift, calling it "deeply frustrating."
Pearson confirmed that its delivery systems for GCSE, A-level, and other qualification results remain entirely separate and unaffected by these specific technical problems.
Whiteman described the situation as "completely unacceptable" and criticized the timing of the announcement, noting the immense pressure already placed on school administrators.
"Totally unfair," he said, adding that school staff face strict accountability measures and expected equivalent standards from the private contractor.
"Schools are held to an extremely high standard when it comes to test administration," Whiteman said.
He warned that failures of this magnitude must carry administrative consequences for the firm involved.
"Small errors can result in serious consequences for school leaders, and the same should be expected of Pearson and everyone responsible for test and exam results," he added.
Association of School and College Leaders General Secretary Pepe Di'Iasio stated the delay would force school staff to manage administrative workloads during their scheduled summer break, calling it a "complete shambles."
Di'Iasio noted that the delay directly penalizes families who are waiting for final academic documentation.
"Parents and children now face an increased wait for these results, with all the anxiety this entails, through no fault of their own," he said.
Whiteman recalled that he had previously sought verification from the Standards and Testing Agency regarding the transition of the contract from previous supplier Capita.
"Reassured that everything was on track," he said, but demanded accountability for the systemic breakdown during this inaugural testing cycle.
"Clearly, though, something has gone badly wrong and Pearson has questions to answer. We would expect serious consequences to follow," Whiteman added.
Pearson's Response and Marker Concerns
A spokesperson for Pearson issued an official statement acknowledging the operational disruption and offering an apology to the markers managing the platform, saying "unreservedly."
An anonymous marker reported to the BBC that internal system deadlines shifted repeatedly throughout June, causing significant administrative strain.
"Just trying to keep up," the marker said, adding that she maintained her workload solely to ensure students received their anticipated July documentation.
"I marked one question that I remembered I had marked before, but the system had assigned the mark I gave to a different question," she said.
The marker noted that system anomalies raise broader questions regarding the ultimate precision of the grading process.
"I reported this, but it raises concerns about whether errors like this could impact final results," she added.
Pearson stated that internal teams are working continuously to process the final sets of pupil data securely.
"Working around the clock to deliver the remaining pupil data," a spokesperson said, stressing that the current focus remains on data accuracy rather than speed.
"Our priority is ensuring that every school and pupil receive complete and accurate results," the spokesperson added.
Whiteman stated that historical precedents of test delivery delays require a formal investigation to prevent future recurrences.
"Not the first time schools have faced delays," he said, concluding that repeated errors undermine the systemic credibility of the entire primary testing framework.
"Once the current issues have been addressed it is vital that they are properly investigated to ensure it is the last," Whiteman added.
The union representative noted that the disruption has placed an unfair burden on families and local educators alike.
"Pupils, parents and schools have been badly let down," he said.
Whiteman argued that the logistical breakdown highlights the structural flaws of the current assessment model.
"Given the fiasco around the marking and return of results, we once again question the whole purpose of these outdated tests," he added.
According to reports from Schools Week, the delay follows a pattern of glitches, including an episode two weeks ago where mathematics markers were diverted to finish outstanding grammar, punctuation, and spelling tests.
The National Association of Schoolmasters Union of Women Teachers previously urged that these core testing assessments be managed entirely within the public sector to maintain institutional stability.
