CO vs EO: Which Civil Service Grade Should You Apply For?

A lot of people sit on this question longer than they should. You know you want a civil service job. You know there are different grades. But the difference between Clerical Officer and Executive Officer is not always obvious from the outside, and picking the wrong one to apply for can cost you a year or more while you wait for the next competition.

Here is a plain-spoken comparison of the two grades: what they pay, what the work is like, how difficult the assessments are, and which one actually makes sense for where you are right now. If you want the full picture on either grade individually, the Clerical Officer competition guide and the Executive Officer competition guide go into each process in detail.

CO vs EO: the basics at a glance

Both the Clerical Officer (CO) and Executive Officer (EO) grades are open to applicants with a Leaving Certificate. Neither requires a degree. That is one of the things that surprises people, because the EO is a meaningful step up in responsibility and pay, yet the minimum eligibility requirement on paper is the same.

What separates them in practice is the level of work, the assessment difficulty, and the salary.

Clerical Officer: Starting salary listed on publicjobs.ie is €31,495. The Forsa scale runs from around €611.75 per week up to €958.80 per week at the long service increment (LSI2), based on rates effective June 2026. CO work is typically administrative, processing-heavy, and customer-facing. You will be handling transactions, correspondence, and queries within defined procedures.

Executive Officer: Starting salary listed on publicjobs.ie is €38,419, with the Forsa PPC scale running from €38,803 to €63,227 at LSI2 (June 2026 rates). EO work sits a level above. You are expected to analyse information, draft reports, manage small teams or workstreams, and exercise more independent judgement. It is a grade where you are expected to coordinate rather than just process.

If you are starting out and the CO rate looks modest, it is worth knowing that progression on the incremental scale is relatively predictable once you are in, and many people use the CO panel as their entry point before going for the EO competition internally.

Are the assessments actually harder at EO level?

Yes, and the difference is significant.

The CO assessment includes verbal and numerical reasoning alongside two tests that are specific to the grade: a checking test (where each question auto-advances after 20 seconds - you cannot go back) and a categorising test. The pressure is real, but the question style is accessible.

CO and EO competitions can use different subjects, response methods and timings. Do not use question counts from an earlier competition or a commercial provider as instructions for your own test. Read your invitation and familiarisation material. For SJT practice, PSP uses five independently rated actions on a six-point scale.

For either grade, use the authority and facts stated in each scenario. Compare your reasoning with the feedback rather than assuming that a familiar workplace response is always appropriate. The free taster lets you try PSP practice before paying.

One important note on the EO figures above: the question counts come from third-party prep providers rather than an official publicjobs.ie information booklet. Always check the competition-specific information booklet when a live competition opens, as formats can vary.

Salary: how far apart are they really?

The starting gap is around €7,000 per year. Over a career that compounds, but the more relevant figure for most candidates is what each grade looks like at the mid-point of the scale rather than just at entry.

At the top of the long service increment, the EO scale reaches €63,227. The CO scale peaks at a rate equivalent to roughly €49,850 per year at LSI2 (based on the weekly figure). The gap widens rather than closes over time.

Neither salary is negotiable. The competition terms fix your starting point on the scale, and that applies whether you are the highest-ranked candidate on the panel or borderline. Salary negotiation is not a feature of these competitions.

Progression: which grade gets you further, faster?

If you enter at CO and perform well, you can apply for internal EO competitions (interdepartmental competitions) when they run. Those are typically less competitive than open competitions because the pool is smaller. Many people deliberately use the CO panel as a foothold and then target EO promotion from inside.

If you enter at EO, your next move is to Higher Executive Officer (HEO). HEO open competitions are less common - promotion from EO level is the more typical route upward. HEO starting salary is listed on publicjobs.ie as €59,435, with the Forsa PPC scale reaching €76,546 at LSI2.

One grade you will hear about alongside these is Administrative Officer (AO). The AO requires a Level 8 Honours degree (first or second class), so it is a graduate-entry route, not an alternative CO or EO path for most candidates. The starting salary is listed as €40,768 - marginally above the EO entry point but with a significant degree barrier attached.

Waiting times and what “on the panel” actually means

This is where a lot of candidates hit an unexpected wall.

Both competitions create a panel ranked by order of merit (OOM). Being placed on the panel does not guarantee you a job offer. Publicjobs.ie states this explicitly. Panels are typically active for around 18 to 24 months. If you rank low on the OOM, or if the panel for your preferred location clears slowly, you may never be called before the panel expires.

Location matters a great deal in practice. Dublin-based panels historically clear faster than nationwide or regional panels, because there are more vacancies in Dublin departments. If you are prioritising a specific county and ranking in the middle of a large panel, you may be waiting for a long time - possibly through to the next competition cycle.

General CO and EO competitions each attract thousands of applicants. The assessment score that determines your OOM position is not just a pass/fail threshold; it is competitive. Meeting the minimum standard is not enough if thousands of people above you on the list get called first and the panel closes before it reaches you.

That is why preparation matters more than most people realise before they sit the tests. You are not just trying to pass. You are trying to rank as high as possible.

Which grade should you actually go for?

Here is an honest answer rather than a hedge.

Go for EO if: you have some experience in an administrative, analytical, or coordinating role; you are comfortable with genuinely difficult time-pressured reasoning tests; and you want to start at a grade where the work and pay reflect a real step up. If you are a graduate with no specific civil service experience, the EO is still accessible - it just demands solid preparation.

Go for CO if: you are new to the workforce or to the Irish civil service system, you want to use the competition as a lower-pressure entry point, or you are not yet confident in the numerical and verbal reasoning required at EO level. The CO route is not the slow road - many CO candidates use it to get in and then go for EO from inside, often through competitions with a smaller applicant pool.

Apply for both if they run at the same time. You can apply for multiple competitions simultaneously. There is no rule against it, and sitting both assessments gives you useful practice and more than one path onto a panel.

Frequently asked questions

Do I need a degree to apply for the EO competition? No. The minimum eligibility for both CO and EO is Leaving Certificate level. A degree is not required for either grade. The one grade that does require a degree is Administrative Officer (AO), which needs a Level 8 Honours degree (first or second class).

Is there a pass mark, or is it all relative? There may be a minimum threshold to progress, but your placement on the order of merit is competitive - it is determined by your score relative to all other applicants. Being above a pass mark does not guarantee a strong panel position. Check the relevant competition booklet on publicjobs.ie for any stated thresholds when a live competition runs.

Can I choose which department I get assigned to? You can submit location and department preferences, but these are not guaranteed. Publicjobs.ie states clearly that assignment is subject to organisational needs. Candidates with a low order of merit number (meaning a high rank) have better practical outcomes in getting closer to their preferences, but even high-ranked candidates have no formal guarantee of a specific assignment.

How long does the whole process take? It varies, and it can take many months from application closing date to starting in a role. The volume of applicants, the batch system for advancing candidates through stages, and post-offer clearance processes all add time. Treat the timeline as “longer than you expect” and plan accordingly.
