Accredited archaeologist grades and what each permits

Accredited archaeologist grades matter to a developer for one practical reason: the county archaeologist can decline to accept a report because of who wrote it, and that costs a determination period. Accreditation in archaeology runs on two tracks, individual and organisational, and briefs are written on the assumption that the developer understands both.

The short version is that individual accreditation describes what a person can take responsibility for, organisational registration describes what a company has been audited against, and most briefs want to see one of each.

The individual accreditation grades and their scope

The Chartered Institute for Archaeologists operates accredited grades that step up with demonstrated competence and responsibility.

There are also non-accredited categories for students and for people working towards a grade. Those are memberships rather than statements of competence, and a proposal that offers "CIfA membership" without naming the grade is telling you less than it appears to.

The grades are competence-based rather than time-served, so the question to ask about a named individual is not how long they have worked but what they have taken responsibility for. On a commercial scheme, the person whose grade actually matters is whoever will sign the report.

Registered organisations and what registration means

Organisational registration is separate and it is audited. A registered organisation has been assessed against the institute's standards and its code of conduct, is subject to periodic inspection, and must have an accredited individual in a responsible post who answers for the organisation's professional work.

For a developer, registration does two useful things. It gives the curator confidence about quality systems, archive practice and staffing, which speeds up approval of a written scheme of investigation. And it gives you a complaints route that exists outside the contract if the work goes wrong.

Registration does not mean every person on the site is accredited, and it does not guarantee capacity in the month you need it. Ask who will actually be on the ground and what their grade is.

Who may author a written scheme of investigation

The written scheme of investigation is the document the curator approves and the contractor then works to. It is the closest thing in archaeology to a design, and curators expect it to come from someone able to take full professional responsibility for the project, which in practice means the top accredited grade or a registered organisation writing under one.

A scheme written by a junior member of staff and issued without that oversight is the commonest reason for a curator to send one back. The second commonest is a scheme that copies standard text and does not engage with the actual site: no reference to the desk study's findings, generic trench positions, no stop point.

Where a scheme covers several phases, say who is responsible for each. A single named person for fieldwork direction and a single named person for post-excavation is what an approving officer is looking for.

Fieldwork direction and post-excavation specialists

Fieldwork direction and specialist analysis are different competences and they are accredited through different routes.

Finds specialists, environmental archaeologists, human osteologists, conservators and illustrators generally work through specialist networks and hold accreditation appropriate to their field. A prehistoric pottery specialist is not interchangeable with a post-medieval glass specialist, and the assemblage determines who you need. That is why post-excavation costs cannot be fixed before the finds are seen.

For standing buildings, the relevant framework is different again. Recording is specified by level against the Historic England scheme, and a Historic Building Recording exercise at the higher levels expects an author experienced in analytical building recording rather than a field archaeologist. Councils treat this as professional recommended work, which means a suitably qualified author and professional review.

The county archaeologist's expectations

The curator's brief is the document that sets the bar, and it usually does so explicitly: work to be carried out by a registered organisation, or by an archaeologist of a stated accredited grade, in accordance with the institute's standards and guidance for the relevant type of work.

Read the brief for three things beyond the sample size. Which standards and guidance documents are named, because those set the methodology you are contracting for. What the report and archive requirements are, because the Historic Environment Record and the receiving museum both have their own rules. And whether the curator names a stop point or a reporting deadline.

An Archaeological Desk-Based Assessment prepared to the same standards is normally the first deliverable, and it is also the one most often produced by someone without the accreditation the curator expects, because it looks like a desk exercise.

Where an unaccredited report is rejected

Rejection rarely arrives as a refusal. It arrives as a consultation response saying the submitted report does not meet the brief and the authority is unable to advise, which means the application sits until it is fixed.

The consequences run through the programme rather than the planning balance.

1. The consultee response lands late in the determination period, so there is no time to redo fieldwork.
2. The council asks for an extension of time or refuses on the grounds that the effect on heritage assets with archaeological interest has not been assessed.
3. Redoing the work costs the full fee again, because the first contractor's data may not be usable.
4. Any seasonal or access constraint on the site applies again from scratch.

None of that is recoverable from the first contractor unless the contract said what accreditation was required. Put it in the contract.

Checking credentials before award

This takes ten minutes and it is the highest-return ten minutes in the procurement.

• Ask for the accredited grade of the named project director and the named report author, not the company's membership.
• Check the individual and the organisation against the institute's published lists rather than the company's own website.
• Ask which standards and guidance documents the proposal follows, and check they match the ones named in the curator's brief.
• Ask who the responsible post holder is if the company is registered.
• Ask for two recent examples of the same document type, approved by a curator in a comparable authority.
• Confirm professional indemnity cover and that the scope of the appointment matches the brief.

Then send the curator the proposed team before you appoint. A curator who has seen and accepted the team will not raise competence later, and that single email removes the risk this article is about.

PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval, and for specialist technical reports, qualified professional input may be required. Drafting can structure a document and check its policy coverage, but fieldwork, finds analysis and professional sign-off sit with an accredited archaeologist. Use the professional directory as the route to review and sign-off, and treat this as general guidance rather than legal advice.
