Two signals. One common language.

GMS produces two complementary data products - both grounded in perception measurement, developed and validated by the GMS Institute. The Social Responsibility Scor(SRS) is the primary signal; the Net Trust Score (NTS) is the trust barometer that travels alongside it. Together they give organisations and practitioners the clearest available read on how the market sees them.

Primary signal

Social Responsibility Score

SRS

The signal in the noise. SRS measures sustainability perception and links those scores directly to commercial outcomes - revenue, share price, market share. One methodology, any organisation, every market.

SRS is delivered through practitioners and accessed via certification. Whether your organisation works with an SRS-certified advisor, builds internal capability or becomes a licensee - SRS gives you the number that moves the market.

Secondary signal

Net Trust Score

NTS

The trust barometer. NTS is correlated with SRS but responds differently to temporal changes - making it a vital companion signal for tracking shifts in public trust over time. Where SRS measures perception of sustainability behaviour, NTS captures the broader trust dynamic that precedes or follows it.

The relationship between SRS and NTS movements - and what drives divergence - is an active area of research for the GMS Institute.

How they work together

SRS measures perception. NTS measures trust. Both move markets.

SRS and NTS are distinct but related - they can confirm each other or reveal divergence. When an organisation's SRS rises but its NTS stays flat, something is being heard but not believed. When NTS moves ahead of SRS, trust is outpacing demonstrated action. SRS is linked directly to financial performance; NTS helps unpack the link to overall market perception.
