The National Student Survey is an annual census of final-year undergraduates at UK universities. It is one of the most widely used data sources in higher education, and CourseMap displays NSS scores prominently on every course page. Understanding what the scores measure - and where they fall short - helps you use them well.
What the survey covers
NSS asks final-year students to rate their experience across eight categories: teaching on my course, learning opportunities, assessment and feedback, academic support, organisation and management, learning resources, student voice, and learning community. Each is scored on a four-point agree/disagree scale, and a percentage in agreement is reported.
CourseMap shows the overall satisfaction score, which combines all categories. You can click through to see individual category scores, which are often more informative than the headline number.
How to interpret the figures
Scores above 80% are generally strong. Scores below 65% indicate consistent dissatisfaction and are worth investigating further. The most important category for academic quality is usually "teaching on my course" - look at that first before drawing conclusions from the headline.
Tip: Compare the "assessment and feedback" score with the "academic support" score. A course where feedback is poor but academic support is high may suit self-directed learners; the reverse may suit students who want frequent, structured feedback.
The known weaknesses of NSS data
NSS scores reflect the experience of students who completed the course, not all who started. High attrition courses may show higher satisfaction because the students who stayed were those who found the course suited them.
Response rates also vary. A course with a 40% response rate is reporting the views of fewer than half its graduates. UCAS and HESA suppress scores with very low response counts to protect individual privacy, which is why some course pages show "N/A".
Subject benchmarks
HESA publishes benchmark scores for each subject, which adjust for differences in student intake and subject area. A Psychology course with an 82% satisfaction rate in a subject where the national average is 85% is performing below benchmark, even though 82% sounds strong in isolation. CourseMap displays subject benchmark context where available.
