About this exam

The ACIArb (Introduction to Alternative Dispute Resolution) is the entry-level qualification offered by the Chartered Institute of Arbitrators. It is designed for people who are new to dispute resolution and want a recognised grounding before choosing a specialism: law students and graduates, junior lawyers and in-house counsel, contract and project professionals, engineers and surveyors, and anyone whose work involves managing conflict. It is an awareness-level award, not a licence to practise, and it does not by itself make you an arbitrator or mediator. The assessment tests breadth rather than deep doctrinal knowledge. You are expected to understand how the main processes differ, when each is appropriate, and the vocabulary and principles that underpin them: the consensual and binding divide, without-prejudice settlement, the difference between mediation and conciliation, how an arbitration is commenced and an award made, the role of the New York Convention and the UNCITRAL Model Law, and the ethical duties of neutrality and confidentiality. Because it is a multiple-choice, single-best-answer assessment, success comes from active recall and careful reading rather than essay technique. Prepare by working through the official syllabus domain by domain, learning the distinctions between processes side by side, and practising scenario questions where two answers look plausible and one is clearly better. Confirm current administrative details with the Institute.

Common questions

About ACIArb (Intro to ADR) preparation

What is the exam format?

It is a computer-based assessment using multiple-choice questions with a single best answer. Each question has one correct option and several distractors that are designed to be plausible, so you must choose the best answer rather than merely a defensible one. The official body publishes the current structure and any variations, so check its website before booking.

How difficult is the ACIArb assessment?

It is an introductory-level award, so the concepts are accessible to newcomers. The difficulty lies in precision rather than depth: questions often turn on a single distinguishing feature, such as whether a process is binding, consensual, or without prejudice. Candidates who have only skimmed the material typically find the scenario questions harder than the definitions.

How long is the assessment and how many questions are there?

Do not rely on second-hand figures. The number of questions, the time allowed, and the pass mark are set by the Chartered Institute of Arbitrators and can change between assessment windows. The current numbers are published on the Institute's own website and in your candidate instructions, so confirm them there before you plan your timing.

Can I retake the assessment if I fail?

Retake arrangements, including any waiting period, fee, and limit on attempts, are governed by the Institute's candidate regulations. These are not fixed across all centres and cohorts. Check the current policy on the Institute's website or ask your training provider before you book, so you know what happens if you do not pass first time.

In what order should I study the syllabus?

Start with the overview of processes and the ADR spectrum, because it gives you the vocabulary and the comparisons everything else depends on. Then work through negotiation and mediation, which carry the most conceptual weight after arbitration. Study arbitration and the legal framework together, since the New York Convention and Model Law make more sense alongside procedure. Finish with ethics and confidentiality.

What are the most common reasons candidates lose marks?

Confusing mediation with conciliation, assuming a mediator decides the outcome, and muddling 'without prejudice' with 'confidential'. Another frequent error is treating arbitration and adjudication as interchangeable when they differ in finality and enforceability. Read the stem carefully: words like 'binding', 'final', and 'consensual' are usually the key to eliminating the wrong options.

Do I need legal experience to take it?

No. The qualification is explicitly an introduction and is taken by non-lawyers as well as lawyers. What you do need is the willingness to learn precise terminology and to distinguish processes that look similar. If you come from a construction, engineering, or commercial background, your practical experience of disputes is an advantage rather than a gap.

Does the ACIArb make me a qualified arbitrator or mediator?

No. It is an entry-level educational award that demonstrates foundational knowledge of dispute resolution. It does not confer practising rights, appointment eligibility, or a licence to sit as an arbitrator or mediator. Progression to further Institute modules and eventual practice requires additional training, assessment, and experience, and you should check the current pathway on the Institute's website.

How should I practise for a single-best-answer exam?

Work through scenario questions and, for every option, write one sentence explaining why it is wrong. This forces you to learn the distinguishing feature rather than recognising a familiar phrase. Review the topics you get wrong within a day, then revisit them a week later. Spaced retrieval beats rereading notes, which tends to produce false confidence.
