AA and AO: What the Entry Grades Actually Involve
What Administrative Assistant and Administrative Officer roles actually involve, who they suit, and how the Behaviours evidence bar works at entry grade.
Some candidates look at AA and AO and decide the grades are beneath what they have already done, then apply at HEO on the strength of a job title that never actually carried line management. Others assume the opposite: that everyone has to start at AA, however much real judgement and decision-making they already bring with them. Both instincts skip past what the entry grades are actually for.
AA and AO sit at the bottom of the grade structure in full, the same seven-grade ladder that runs from admin support through to the Senior Civil Service, as set out on the Civil Service Careers grades and pay page. This post sets out what the work at these two grades genuinely involves, how AA and AO actually differ from each other, who they suit, and why entering deliberately at AO, rather than drifting into it by default, is often the stronger move.
What does AA and AO work actually involve?
Administrative support and operational delivery, mostly, done directly rather than through anyone else. “AAs and AOs play an essential role in government departments, usually in administrative support or operational delivery roles,” according to the Civil Service Careers grades and pay page. They are described there as “entry level or junior roles where responsibilities vary widely depending on the department,” and the page states plainly that “these roles are good with less experience.”
The responsibilities named on that page cover handling enquiries by phone, in person or online, scheduling meetings and arranging travel, filing documents and other administrative tasks, referring complex work or queries upward, keeping accounts up to date, and updating information systems such as databases and electronic records. That is a wide brief on paper, and the department fills in the rest: it could mean processing casework at DWP, managing correspondence at the Home Office, or general administrative support in a smaller agency.
Entry into both grades happens the same way: “direct applications or apprenticeships,” with no prior Civil Service background assumed. The equivalent roles outside the Civil Service, per the same source, are “office administrator and executive assistants.”
How does AA actually differ from AO?
Officially, barely at all in terms of documented duties, though department-level pay data shows AO does sit a real step above AA. On its main grades and pay page, Civil Service Careers does not separate the two: it lists them as one combined grade, “Administrative Officer/Administrative Assistant (AO/AA),” with a shared responsibilities list and a single average starting salary of £23,000, checked 9 August 2026 on the grades and pay page.
Individual departments draw the line more clearly. Defra’s own breakdown lists an AA national minimum salary of £25,445 against an AO national minimum salary of £26,025, checked 9 August 2026 on Defra’s Civil Service grades page. The same page states: “While AAs are entry level positions, both roles are also offered as apprentice opportunities.” That is the clearest official signal available: AA is the more junior of the pairing, AO is the step above it, and the practical gap between them is set locally rather than nationally.
Treat your own advert as the authority on which grade you are actually being assessed against. Where a department has not drawn the line as clearly as Defra has, AA and AO function as one banded entry point in practice.
Who does the AA or AO grade genuinely suit?
People arriving without a Civil Service track record and without a manager’s title to point to. That covers career changers moving out of retail, hospitality or a trade into office-based work for the first time; people returning to work after a break for caring responsibilities, illness or redundancy who need a role that will take a gap on the CV in its stride; and anyone testing whether public sector work suits them before committing to it as a career, rather than stretching a first application over a grade that expects evidence they do not yet have.
None of that makes AA or AO a lesser choice. It is real casework, real correspondence, real service delivery, done by people whose department depends on it being handled accurately. Civil Service Careers frames it exactly that way: AAs and AOs “play an essential role in government departments.” Treating the grade as a consolation prize misreads both the job and the people doing it well.
Is the Behaviours evidence bar real at AA and AO grade, or is it just a formality?
It is real, and it is written down in full. Success Profiles Behaviours are assessed at a level “specific to the grade level of the job role,” according to the official Behaviours guidance, last updated 29 January 2025, and the AA/AO band has its own complete set of descriptors across all nine Behaviours, not a watered-down subset of a higher grade’s expectations.
For Delivering at Pace, the AA/AO descriptor expects you to “always work with focus and pace to get the job done on time and to a high standard” and to “keep a consistent level of personal performance,” per the same guidance. For Working Together, it expects you to “proactively contribute to the work of the whole team and remain open to taking on new and different roles.” For Managing a Quality Service, it expects you to “gain a clear understanding of customers’ needs and expectations.” None of that is trivial to evidence well. An answer that just describes turning up and finishing tasks on time will not clear it. The framework wants a specific example of focus, contribution or customer understanding, not a general claim of being reliable.
What genuinely changes at EO and above is scope, not rigour. At EO grade, Delivering at Pace expects you to “identify who and what is required to ensure success” and to “regularly check performance against objectives,” per the same source: managing a plan, not just your own output. AA/AO evidence answers for your own delivery. EO evidence answers for a piece of work that involves other people’s. That is a real distinction between the grades, not a lower bar dressed up as one.
Why apply at AO deliberately, rather than aiming higher?
Because the grade is built to be entered without Civil Service experience, and applying against a bar you can clear now beats applying against one you cannot yet evidence. HEO adverts already expect “some experience in the business area or technical specialism,” per Civil Service Careers, and SEO adverts look for an “experienced manager” who can act “as role models for Civil Service behaviours.” If your evidence does not stretch that far yet, an AO application built around real, well-evidenced examples of personal delivery and customer service will consistently beat an HEO application stretched thin over experience you do not have.
AO also gives you something an external application to a higher grade cannot: a genuine, verified track record inside the system, built on real casework rather than a CV line someone else has to take on trust. That record is what your next application draws on, and it is worth more than the grade of your first job title.
Can you move up once you are in?
Yes, and the route is structural rather than informal. Once you hold a Civil Service Jobs account as a serving civil servant, verified against your work email, or your line manager’s if you cannot access it, that verification “gives you access to internal job opportunities” that an external applicant never sees. Civil Service Jobs guidance states plainly that “you will not be able to see all vacancies that you’re eligible to apply for if your account is not verified,” according to the guidance on using the Civil Service Jobs website, last updated 27 January 2026.
From AO, the usual next step is EO, then HEO. The grades keep changing in scope well beyond that, and what changes again once you reach SEO is a different jump again, worth reading once EO and HEO are behind you rather than while you are still deciding whether to apply at AO at all.
How is AA/AO pay actually set?
By department first, then by location, not by a single national figure. Departments “have delegated authority to decide on pay and conditions for their workforces below the Senior Civil Service,” operating “within the delegated framework and controls” the Cabinet Office issues annually, according to the Civil Service Pay Remit Guidance 2026 to 2027, published 21 May 2026. For 2026/27, that guidance sets the overall pay pot departments can spend, the Increase to Remuneration Cost, at a maximum of 3.5 percent, a budgetary ceiling rather than a promise about what any individual receives.
The two figures already used in this post show why a single number would mislead you more than it would help: £23,000 as a general average starting salary against Defra’s own £25,445 for AA and £26,025 for AO, both checked 9 August 2026. Same pair of grades, two different official figures, because pay is set locally within a national framework. Why the same grade pays differently works through the mechanics behind that gap properly. The number that actually applies to you is the one printed on your own advert, not this page.
FAQ
Do I need Civil Service experience to apply for AA or AO roles? No. Civil Service Careers lists direct applications or apprenticeships as the entry routes for both grades, with no prior government background assumed.
Is AA definitely a lower grade than AO? In practice, mostly. The general Civil Service Careers page treats them as one combined band, but where a department separates them, such as Defra, AA is described as the entry level position with AO the step above it.
Will every AA or AO advert assess all nine Behaviours? No. The job description states which Success Profile elements and which Behaviours apply to that specific role. Read your own advert rather than assuming.
What salary should I expect at AA or AO? It depends on the department and location, and the two official figures in this post already differ by over £2,000 for the same pair of grades. The advert for the specific role carries the number that applies to you.
Can I apply above AO if I already have relevant experience? Sometimes, if your evidence already matches what EO or HEO adverts expect. This post has focused on the honest case for AO. If you suspect your background clears a higher bar, weigh it against the EO and HEO grade descriptions directly before deciding.
Where to look next
If AA or AO looks right, the next useful step is reading a live advert end to end against the specific Behaviours it names, rather than against a generic list. If you already suspect your experience clears a higher bar, check the EO and HEO grade descriptions directly before you commit to starting lower than you need to.
