Kryterion

**Its first genuine claim to precedence is worth checking against the rest of this cluster. Kryterion says it introduced online proctoring in 2005** - fourteen years before Pearson VUE launched OnVUE, and fifteen before the pandemic made remote delivery the only option. The claim comes from the company's own history page and should be read as such, but the direction is clear enough: **the capability existed, was commercially available, and was not widely adopted until circumstances removed the alternative.** That is the ordinary pattern for infrastructure, and worth remembering next time something is described as unprecedented.

**The business model is the real difference from the two larger networks, and it is a genuine architectural choice rather than a marketing distinction.** Pearson VUE and Prometric are full-service: the client hands over an exam and the network delivers it. Kryterion sells **Webassessor**, a platform on which clients build, modify and publish their own examinations - with the explicit selling point that changing an item does not incur a publishing fee. **One model treats the exam as something you outsource; the other treats it as something you operate.** Which suits an organisation depends entirely on whether its examinations change often, and organisations reliably underestimate how often theirs will.

The centre network is around a thousand locations against several thousand for the larger networks, which is a real limitation and an honest one. **A smaller network is a smaller reach**, and the answer to it is the online and event-based delivery the company leaned on early.

**And then the strategic difference that makes this entry worth reading beside Credly's.** Kryterion assembles its stack by partnership: **CloudShare for virtual lab environments, TrueAbility for performance-based assessment, and Credly for digital credentials** - the same Credly that Pearson bought outright in 2022. **The identical functional stack, assembled by acquisition on one side and by partnership on the other.**

Neither is obviously correct. Acquisition guarantees the capability is there and can be integrated deeply; it also concentrates the trust chain in one owner, which is the observation this site made about Pearson and repeated about ETS's ownership of Prometric. Partnership keeps the pieces independent, so a customer's credential provider is not their exam provider's subsidiary; it also means the pieces can change hands, be discontinued, or start competing with you. **The question is not which structure is better but which failure you would rather have**, and that is a question most buyers never realise they are answering.

Kryterion also supports third-party performance-based examinations inside a proctored browser, which is the hybrid the whole cluster has been converging on: **the realism of a practical assessment with the identity verification of a supervised one.** Whether that combination inherits the strengths of both models or the weaknesses is not yet answerable from the public record - the approach is too new, and the failure modes of assessment take years to surface.
