Versions, changelog and archive

Why a version number matters here

The public register records which version of the standard each credential was assessed against. That record is worth nothing unless the version behind it is still readable. If NBOP quietly replaced the standard and deleted what came before, every credential issued under the old text would become an assertion nobody could check, including the holder.

So versions are dated, superseded rather than overwritten, and archived rather than deleted. This page is where that happens.

The release cycle

Six months, published in advance, for all three things that can change.

The item bank is the set of assessment questions. It does not exist yet because the assessment is not open, and it will appear in this table with its own version and dates on the day it does. Listing it now with nothing in it is the honest way to show what is missing.

What end of life means, and what it does not

For the standard. On 17 February 2027 version 0.1 stops being the current text. It does not stop existing. It moves to the archive below, keeps its address, and stays readable.

For a credential you already hold. Nothing happens. A credential runs for three years from issue regardless of how many versions of the standard come and go inside that term. It was a true statement about you on the day it was issued and it remains one. When you recertify, you sit against whatever is current then, which is why recertification is an assessment rather than a payment.

For an employer checking a credential. The register tells you which version the holder was assessed against, and this page tells you what that version said. Those two facts together are the whole point of publishing a standard rather than asserting a competency.

Changelog

Version 0.1 · Draft · 17 August 2026

Initial publication of scope, the eight domains, and the assessment principles. Domain weighting is not yet set and is stated as provisionally equal rather than implied. Open for comment. End of life 17 February 2027.

Every future entry carries what changed and why, not just that something did. Where a change follows from the job task analysis, the entry says which finding drove it, including findings that contradicted the draft.

Archive

Nothing is archived yet, because nothing has been superseded. Version 0.1 is both the first version and the current one.

When it reaches end of life on 17 February 2027 it will be archived at a permanent address listed here, and that address will not change afterwards. Archived versions are marked superseded at the top of the page so that nobody mistakes an old text for the current one, and they are excluded from search indexing for the same reason.
