OfS corrects TEF data dashboard calculations, what institutions should check in student experience evidence

By Student Voice AI

Published Feb 21, 2026 · Updated Feb 21, 2026

On 5 February 2026, the Office for Students (OfS) updated the TEF data dashboard and data files after identifying an error in how some benchmark-related statistics were calculated. At Student Voice AI, we see TEF and NSS metrics pulled into everything from committee packs to action planning dashboards. This update is a useful prompt to check that your student experience evidence is built on the latest data release. [OfS TEF data]

What has changed in the TEF data dashboard

The OfS says it has updated the TEF dataset after finding an error in the calculation of the standard error for the difference from benchmark estimates. In practical terms, this affects the uncertainty around how far a provider sits from its benchmark, which can feed into how differences are interpreted in internal reporting.

"The data has been updated after an error was identified in the calculation of the standard error for the difference from benchmark estimates."

The OfS also flags a separate, minor issue: a problem with the split benchmarks for student experience. The page notes that corrected data would be released alongside a new dashboard on 19 February 2026.

For context, the TEF dataset includes student outcomes and student experience measures for registered providers in England, drawing on multiple sources including the National Student Survey (NSS) student experience indicators. Not every indicator is used in every TEF assessment, but these measures often become a default reference point for “how we are doing” on the student experience.

What this means for institutions

If you use TEF data in quality, planning, or governance, the first action is simple: refresh your TEF extracts and re-run any analysis that uses benchmark differences or significance flags. If you have already built charts, narrative, or board papers using an earlier version, update them and record the release date you used.

Second, treat this as a governance reminder. When sector datasets change, teams need a clear answer to: which version of the data is in our pack, and when did we last refresh it? A lightweight approach is enough: a named owner, an agreed refresh cadence, and a short methodology note attached to dashboards and committee papers.

Third, this is where student voice matters. Even when benchmarked indicators move, you still need to explain what is driving the experience for your students, and what you are doing about it. That is easiest when quantitative measures are paired with governed qualitative evidence, particularly open-text comments that make the “why” legible.

How student feedback analysis connects

If TEF and NSS data is the headline, open-text is often the diagnostic. A stable approach to analysing student comments helps you move from “the metric shifted” to “these are the themes that drove it, and this is what changed after interventions”.

For teams looking to strengthen the link between survey metrics and action, two practical starting points are our NSS open-text analysis methodology and the student comment analysis governance checklist.

FAQ

Q: What should we do now if we use TEF data in student experience reporting?

A: Re-download the TEF data, re-run any benchmark and “difference from benchmark” reporting, and update any committee packs or dashboards that use those figures. Add a simple note stating the data release date, so future readers can tell which version your analysis used.

Q: Which providers and measures does this update affect, and when does it apply?

A: The OfS TEF dataset covers registered providers in England and includes student outcomes and student experience measures, including NSS-derived indicators. The TEF data page was updated on 5 February 2026, and it also notes a correction related to split benchmarks for student experience that would be released on 19 February 2026.

Q: Does this change how we should use student voice evidence for TEF and quality work?

A: It reinforces a core principle: metrics need context. Benchmarked indicators are useful, but they are more actionable when paired with a governed view of what students said in their own words, and a traceable record of what the institution did in response.
