How it is assessed

Forty questions drawn from Track A, 75% to pass, two attempts per 24 hours. Roughly a third of the questions give you real output (an EndpointDescription, a DataValue, a NamespaceArray) and ask you what it tells you.

What it is aligned to

Aligned to the conformance units behind the core client facets: discovery and endpoint retrieval, session establishment, attribute read and write, view browsing and browse-path translation, and data-change monitored items with filters.

What this credential is not: This credential is issued by OPC UA Connect and by nobody else. Certification in the OPC UA ecosystem is a product-level programme: a specific product version is tested at an independent laboratory against named profiles and facets. We are not aware of any individual, person-level OPC UA certification offered by the specification's publisher or by any standards body. So this certificate is not issued by, recognised by, endorsed by, accredited by or equivalent to any such programme, and it should not be described as one. What it does assess is real, and the profiles and facets it is aligned to are public and named: see our disclosure page for how we state all of this.

The exam needs a free account.
