04 · Time series
Current questionnaire period, 2023–2026
The 2023 NSS questionnaire redesign creates a comparability break. We show earlier years separately as context rather than drawing a trend through 2022–2023.
| Year | Comments | Mention rate | Sentiment index |
|---|---|---|---|
| 2023 | 2,804 | 5.2% | −48.9 |
| 2024 | 3,996 | 6.3% | −48.6 |
| 2025 | 3,064 | 5.1% | −46.2 |
| 2026 | 2,220 | 5.4% | −43.8 |
Show historical context, 2018–2022
All years were analysed with the same deterministic supervised learning approach, but the survey instrument differs from the current questionnaire.
| Year | Comments | Mention rate | Sentiment index |
|---|---|---|---|
| 2018 | 2,678 | 5.6% | −43.7 |
| 2019 | 3,126 | 5.8% | −43.9 |
| 2020 | 2,742 | 5.5% | −43.4 |
| 2021 | 3,663 | 5.1% | −46.0 |
| 2022 | 3,841 | 5.0% | −46.2 |
05 · Action
Three evidence-linked actions
Use the findings to choose a local test, then check the same topic and cohort again rather than treating a sector pattern as a diagnosis of one provider.
-
1
Turn criteria into shared judgements
Use plain-language criteria, annotated work at different standards and marker calibration before high-volume assessment begins.
Evidence: 2,220 reportable comments in 2026, 5.4% of classified comments.
-
2
Start with the clearest variation
Test the process with (CAH04) psychology first, where the 2026 sentiment index is −52.6 from n=123 comments.
Evidence rule: no displayed cohort or subject cut has fewer than 20 comments.
-
3
Set the next-cycle check now
Audit consistency and track whether students can explain how criteria were applied to their own work.
Compare 2027 with 2026 on a like-for-like basis before describing movement.
06 · Method and limits
How to read this evidence
How topics are identified
Deterministic supervised learning models identify topics in each sentence. A comment counts once in every topic it mentions; mention rate is the share of comments included in the analysis for the same population, so topic rates do not sum to 100%.
Sentiment index
The index summarises the balance of positive and negative language from −100 to +100. Scores are averaged within each comment first, so longer comments do not carry more weight.
When results are shown
Pages require at least 100 comments and three reportable topics or subject cuts. Displayed cuts require n≥20; 2026-versus-2025 claims require n≥30 in both years.
Scope
This is authorised aggregate analysis of OfS NSS national undergraduate open-text comments. In 2026, 40,822 of 43,870 source comments were classified (93.1%); mention-rate denominators exclude unclassified comments.
