Sussex reports NSS gains and an 80% response rate

Updated Sep 07, 2026

Sussex's NSS results page, updated on 10 July 2026, reports increased positivity across all seven themes and all but one question. It describes an 80% response rate, its highest ever, and credits work on assessment, student voice and module evaluation.

Those are institutional claims about participation and progress. They do not establish that increasing response rates or changing an evaluation system caused the score gains.

What the page reports

Sussex gives 80% positivity for student voice, 79.5% for assessment and feedback, 94.5% for staff explaining things and 92.8% for library resources supporting learning.

It describes an eighth-place position for course organisation and a 31-place rise for student voice. The page defines its comparison group as 131 providers appearing in the 2026 domestic institutional league tables. Those ranks should not be presented as comparisons with every higher education provider or confused with the OfS's statistical benchmark calculations.

The announcement links the student voice improvement to a new approach to module evaluation. An April Sussex notice describes spring module surveys and attributes earlier changes in guidance, learning materials and teaching to feedback. Neither announcement provides a controlled evaluation of the module-evaluation approach or a causal estimate for NSS outcomes.

Participation is one part of evidence quality

An 80% return tells us a large proportion of eligible students participated. It does not alone establish that respondents mirror every relevant characteristic of the full population, or that the nonrespondents' views would be similar.

Review participation patterns and any known gaps alongside the results. The direction and size of nonresponse bias cannot be inferred from a response rate alone. A change in who answers can also affect comparisons over time.

Investigate the claimed connection to action

If an institution attributes better results to a local change, look for evidence of its implementation, who experienced it and what students subsequently described. Consider other changes and differences between cohorts. A sequence of action followed by a higher score is a useful starting point for questions, not sufficient proof of effect.

Question-level findings and comments can help focus that inquiry. Keep their limits clear: comments describe respondents' experiences and possible explanations, not a complete account of why an institutional score moved.

Document interpretation and follow-up

Our NSS open-text methodology can help make category definitions and interpretive decisions visible. Use it alongside appropriate operational evidence and direct student discussion, retaining differences between NSS and local survey contexts.

A decision record should state the issue, evidence considered, responsible team and planned review. Where the evidence cannot support a conclusion, preserve that uncertainty. This is practical advice; it is not evidence that Sussex uses our service or that another provider can reproduce its results through comment analysis.

FAQ

Did Sussex report an 80% response rate?

Yes. It described that as its highest ever.

Does that prove the results are representative?

No. Participation is relevant, but nonresponse patterns and coverage still need consideration.

Did the announcement prove the effect of the module-evaluation approach?

No. It attributes improvement to that work without isolating its causal contribution.

Correction, 7 September 2026: Distinguished the page's update date from publication, clarified the ranking comparison group and qualified claims linking response rates or module evaluation to score changes. Removed ambiguous percentage-change conversions and unverified historical trend implications.
