PSO-Prestatieladder (Prestatieladder Socialer Ondernemen)
PSO-Prestatieladder is a TNO-developed inclusion rating that over 200 Dutch contracting authorities have used as a procurement instrument since 2012. More than 800 organisations now hold the PSO mark, and the scheme's own site states it can be used directly as a gunningscriterium, an award criterion in tenders.

What it is
The scheme owner's own page states, verbatim: "PSO staat voor Prestatieladder Socialer Ondernemen. We zijn een wetenschappelijk onderbouwd keurmerk ontwikkeld door TNO en we maken inzichtelijk hoe inclusief een organisatie is." (Translation note, not verbatim: PSO stands for Prestatieladder Socialer Ondernemen. It is a scientifically grounded quality mark developed by TNO, and it makes visible how inclusive an organisation is.)
The procuring-organisations page states, verbatim: "Al sinds 2012 werkt het PSO-keurmerk als inkoopinstrument voor ruim 200 aanbestedende diensten in Nederland. Op dit moment zijn ruim 800 organisaties in diverse sectoren gecertificeerd voor hun bijdrage aan de arbeidsparticipatie van kwetsbare groepen." (Translation note, not verbatim: since 2012, the PSO mark has worked as a procurement instrument for more than 200 contracting authorities in the Netherlands; more than 800 organisations across sectors currently hold it for their contribution to the labour-market participation of vulnerable groups.)
The same page states, verbatim: "Je kan het PSO-keurmerk ook inzetten als gunningscriterium, waardoor je bedrijven aanmoedigt om te beginnen met sociaal werkgeverschap." (Translation note, not verbatim: the PSO mark can also be deployed as a gunningscriterium — an award criterion — which encourages companies to start with socially responsible employership.)
The same page states, verbatim: "PSO is objectief en wetenschappelijk onderbouwd door TNO." (Translation note, not verbatim: PSO is objective and scientifically grounded by TNO.)
Who owns it
TNO developed the underlying methodology, per the scheme's own page ("ontwikkeld door TNO"). The pages opened this round name only "PSO" and "TNO" — a separate administering legal entity's exact name was not confirmed verbatim and is not asserted here.
