Museum visitor NPS: what is a good score, and how to read yours

Three recent, real visitor studies illustrate the problem:

• Culture Counts, Arts and Culture Benchmark Report FY23/24: 93,000 survey responses across more than 500 surveys, scored out of 100 on dimensions such as aesthetic experience (median 88), inclusion (84) and challenge (73). No NPS is reported.
• Museums Aotearoa, 2026 National Visitor Survey (New Zealand): 135 visitors across museums and galleries; overall satisfaction 9.3 out of 10, up from 8.9 in 2025; 58.6% rated their visit 10/10. A 10-point satisfaction scale, not NPS.
• accesso, Voice of the Visitor 2026: sentiment analysis of 813,000 online remarks from 500 attractions in 37 countries; history and cultural institutions average 4.62 out of 5 against an industry average of 4.18. Online reviews, not a survey.

Different scales, different samples (135 people versus 93,000 answers versus 813,000 reviews) and different moments of asking (at the exit, at home, weeks later online). None of them can be set against your own NPS. Treat any single "museums average X" figure you find online with the same caution unless its method is published.

NPS is the share of promoters (9–10) minus the share of detractors (0–6). Because it is built from two shares, its margin of error is wider than most people expect. With pP the promoter share and pD the detractor share, the variance of one answer is pP + pD − (pP − pD)², and the 95% margin of error in points is roughly 1.96 × √(variance ÷ n) × 100.

Responses (n)	Example: 50% promoters, 20% detractors (NPS +30)
100	about ±15 points
400	about ±8 points
1,000	about ±5 points
4,000	about ±2.5 points

Two practical rules follow. First, report the response count beside every score. Second, do not read a change smaller than the margin as a change: a move from +30 to +34 on 200 answers a month is noise, on 4,000 it is a signal. The tool on this page does this calculation for your own figures.

Museum audiences change with the calendar: school groups in term time, families in the holidays, international visitors in the high season, locals in the rain. Each group answers differently, so a museum that compares July with October is mostly measuring who came, not what changed.

• Compare the same period year on year, or compare weeks within one season.
• Record the language and, where you ask it, the visitor origin with every answer, so the mix can be read next to the score.
• Keep the question and the channel constant; a kiosk at the exit and an e-mail a week later reach different people.

The most useful museum benchmark is internal: the permanent collection against the temporary exhibition, this exhibition against the previous one in the same space, the café against the shop. For that comparison to be fair:

1. Measure each space separately, with its own kiosk or QR code, so the answer is tied to the place.
2. Ask the same one question in every space, with the same scale.
3. Combine correctly. Add up promoters and detractors across spaces and calculate once; averaging the NPS of each space over-weights the small ones.
4. Read comments by space. A score tells you where; the comments tell you why.

If no external number can be trusted, make your own, in four steps:

1. Baseline: run the same question at every touchpoint for one full season and record the score, the margin and the response count per space.
2. Target: set a target per space that is larger than its margin of error, for example "+5 points at 1,000 answers", not "+2 points at 150".
3. Act on the lowest space first: the comments show the reason; a low rating should open a ticket for the responsible person the same day.
4. Report the trend, not the snapshot: season against the same season last year, with the response counts, to the director and the board.

Qmeter runs this as a continuous programme: one survey per touchpoint in the visitor's language, live NPS and satisfaction per gallery with the response count beside it, tickets for low ratings and scheduled reports per season.
