ExploreAbout this exam
The ERA Senior Civil Servant Examination is a competency-based selection assessment for experienced public administrators moving into, or already holding, senior civil service positions. It is designed for candidates who already understand how government machinery works and are now being tested on judgement at the level where policy, law, money, people and politics intersect. Rather than rewarding recall of a single syllabus, the exam asks you to reason through realistic administrative problems: a policy that must be designed under uncertainty, a regulatory decision with legal exposure, a budget trade-off, an underperforming team, a stakeholder who cannot be ignored.
The assessment mixes written and oral components, so preparation has two halves. The knowledge half means working through the substantive domains - policy analysis, law and regulation, public finance, economics, governance, project and change management, data and digital literacy, communication, ethics - until you can apply them rather than recite them. The performance half means practising under realistic conditions: timed written exercises, structured competency interviews, group exercises and oral presentations, ideally with a critical reader who will challenge your reasoning.
Strong candidates read widely, write constantly in the crisp style senior officials expect, and rehearse evidence-based argument. Candidates should confirm current format, timing, fees and scoring directly with the official examining body, which publishes the authoritative details on its website.
What you'll study
About ERA Senior Civil Servant Exam preparation
What does the exam actually feel like on the day?
Expect to be assessed in more than one mode: written work under time pressure, then oral components such as a structured competency interview, group exercise or presentation. The written parts reward structure and brevity over volume; the oral parts reward calm, evidence-based reasoning. Confirm the exact sequence and timings with the official body, which publishes the current schedule.
How difficult is it compared with other civil service exams?
It is pitched at senior level, so difficulty comes less from obscure facts than from the quality of judgement expected. You need to prioritise, justify trade-offs and defend decisions under challenge. Candidates who are strong analysts but weak communicators routinely find it harder than they expect.
Can I retake it, and how often?
Retake rules, waiting periods and any limits on attempts are set by the examining body and can change between cycles. Do not rely on secondhand advice from forums. Check the official website for the current policy before you plan your preparation timeline around a possible second sitting.
What is the biggest cause of failure?
Answering the question you prepared for rather than the one asked. In written exercises this means ignoring the stated audience or decision required; in interviews it means giving generic competency stories with no measurable outcome. A second common failure is unbalanced preparation: heavy on knowledge domains, thin on rehearsed oral performance.
In what order should I study the domains?
Start with policy analysis, because it underpins how you frame every other answer, then law and public finance, which supply the constraints you must respect. Add leadership and governance next, and treat economics, data, communication and ethics as lenses you apply throughout rather than separate subjects to be finished.
How much writing practice do I need?
More than feels comfortable. Senior written exercises are judged on structure, prioritisation and concision, and those are trained habits, not knowledge. Write timed answers weekly, then cut each by a third without losing the argument. Have someone senior to you mark them critically and tell you what a decision-maker would find missing.
Are there official past papers or a syllabus?
The examining body publishes whatever guidance, syllabus material and sample questions it chooses to release, and this varies by cycle. Use only material from the official site for format and expectations. Treat third-party commercial question banks with caution, since they are not endorsed and may not reflect current practice.
How do I prepare for the competency-based interview and group exercise?
Build a bank of eight to ten real situations covering leadership, delivery under pressure, stakeholder conflict and ethical judgement. For each, know the situation, your specific action, your reasoning and the measurable result. Rehearse aloud with a critical listener, and practise group exercises where you must influence without dominating.
How far ahead should I start preparing?
Most successful candidates give themselves several months of steady, weekly work rather than a last-minute sprint, because the writing and oral skills need repetition to become reliable. Fix your start date from the official exam date once published, and protect a weekly block for timed practice you cannot move.
