How to become a chartered accountant in France: DCG, DSCG, DEC and the training route

Qualifying as a chartered accountant (expert-comptable) in France is not the result of aptitude alone. It is a formally regulated, multi-stage journey that combines three state diplomas, a three-year professional placement, and a professional dissertation. The pathway is well documented — but its practical reality raises questions that prospectuses rarely answer directly: how long does it genuinely take, where are the hardest stages, does the apprenticeship route make sense, and what does the profession actually look like once the qualifications are in hand?

This article addresses those questions in the order they arise, from choosing how to enter the route through to the first year of registered practice.

The official route to qualifying as an expert-comptable in France rests on three successive diplomas: the DCG (bac+3, 13 taught units), the DSCG (bac+5, 7 units), and the DEC (bac+8), awarded after a three-year professional placement and three final assessments covering professional ethics, statutory and contractual review, and a professional dissertation. Examinations are run by the SIEC; diplomas are issued by the ministry responsible for higher education (MESR).

The expertise comptable pathway is structured around three successive state diplomas, each validating a level of professional competence and opening access to the next.

Examinations are organised by the SIEC (service interacadémique des examens et concours). Diplomas are issued by the Ministère de l'Enseignement Supérieur et de la Recherche (MESR). Final registration with the Ordre des Experts-Comptables — which follows the DEC and the validated placement — is the condition for practising under the protected title.

The profession numbered around 22,000 registered experts-comptables at the time of the most recent Ordre publications, which gives a sense of the real selectivity of the full pathway.

The answer depends on the entry point, any equivalences that apply, and the pace at which each diploma is validated. For a candidate entering directly after the baccalauréat on a smooth trajectory:

• 3 years for the DCG;
• 2 years for the DSCG;
• 3 years of professional placement;
• DEC presented during or at the end of the placement.

That implies a minimum of 8 years between the baccalauréat and Ordre registration, assuming no retakes on any taught unit. In practice, retakes on one or two DSCG units, a change of employer during the placement, or an initial unsuccessful dissertation defence often add one to two years to the timeline.

Some profiles move faster via equivalences. A graduate of a grande école or a master's in accounting and control (master CCA) can obtain exemptions from several DCG and DSCG units, entering the placement stage earlier. The equivalence framework is strictly regulated and must be verified with the SIEC before making any orientation decision.

The Diplôme de Comptabilité et de Gestion (DCG) covers 13 taught units across company law, tax law, corporate finance, advanced accounting, management control, information systems, and business English, among others. It is structurally more demanding than a BTS, because it requires sustained effort across subjects that follow different internal logics.

The DCG trains technicians capable of working in a practice or a finance department. More importantly, it prepares candidates for what follows: the DSCG and the analytical dimension of the profession. Students who treat the DCG as an end in itself — focusing purely on passing units — often find the transition to DSCG level harder than their initial results would suggest.

For candidates who aim at practice careers without necessarily targeting the DEC, the DCG also opens paths to roles as an accountant, senior collaborator or engagement manager. The alternance en comptabilité article explores the apprenticeship dimension in detail.

The Diplôme Supérieur de Comptabilité et de Gestion (DSCG) comprises 7 taught units. The level of complexity increases sharply: examination questions require synthesis, cross-subject reasoning, and the ability to think like a practitioner — not simply to reproduce course content.

UE 4 (accounting and audit) and UE 1 (legal, tax and social management) are consistently cited as the most selective. UE 4 requires simultaneous command of French GAAP, IFRS principles and audit methodology — a combination that challenges candidates from purely technical backgrounds.

In the files we see at Hayot Expertise, candidates who pass the DSCG efficiently tend to be those who started working in a practice during the DCG and had already applied their knowledge to real-world situations. Apprenticeship during the DSCG plays a particularly structuring role here.

The Diplôme d'Expertise Comptable (DEC) comprises three assessments:

1. Professional ethics and regulatory framework: the legal and ethical framework governing the profession — professional secrecy, independence, AML obligations, engagement letters, and so on.
2. Statutory and contractual review: applying audit and review techniques, NEP standards, and producing professional reports.
3. Professional dissertation (mémoire): a substantive research piece on a subject relevant to the profession, defended before a jury.

The dissertation is consistently the most underestimated element. It is not a placement report: it is a genuine academic work that requires months of research, structured writing and argumentation. Candidates who leave it to the final year of the placement — without having progressed it in parallel — regularly find themselves in a difficult position.

The DEC is presented during or after the three-year placement. There is no fixed date obligation, but the placement must be fully validated before the dissertation defence can take place.

Apprenticeship is available at every stage of the route — DCG, DSCG and the DEC placement. Its advantages are real: immediate connection between coursework and professional practice, income during the course, and early development of a professional network.

But apprenticeship is not suited to every profile. It requires rigorous organisation, the ability to manage academic and professional demands simultaneously, and — a point frequently overlooked — an employer who genuinely trains. Not every practice offers the same quality of apprenticeship supervision. A trainee placed on data entry tasks without structured guidance loses on both counts: neither the sustained focus of full-time study, nor exposure to formative work.

Our view at the practice: before signing an apprenticeship contract, evaluate the host structure — its size, the range of engagements you will be exposed to, its training policy, and the commitment of the designated workplace supervisor. A structured practice with a genuine supervision policy adds real value; an employer who treats the apprentice primarily as a production resource, considerably less.

Compensation on entering the profession varies by practice size, geography and candidate profile. Industry studies published annually by professional associations and specialist recruitment firms distinguish several situations.

These ranges are indicative and shift year on year. They should be read in light of the type of structure (Big Four, mid-tier network, independent practice), the candidate's specialisation, and the level of responsibility at the point of hire. The étude des salaires audit conseil et expertise comptable 2026 published on this site provides more granular data by category.

A newly registered expert-comptable who joins a practice as a partner — or who sets up independently — operates in a different economic model: remuneration then depends directly on portfolio development and the terms of any partnership. The chef de mission comptable article helps position the intermediate stages between senior collaborator and partner.

The school-leaver with a long-term vision#

The student who enters the DCG after the baccalauréat with a clear motivation — not simply because the qualification « opens doors » — has a structural advantage. They build sound working habits from the outset, gain early practical exposure through apprenticeship, and are not destabilised by the length of the route because they had anticipated it.

The master's or business-school graduate#

Some candidates join via equivalences after a master CCA, a finance master's or a grande école programme. The advantage is analytical maturity that often exceeds the DCG norm. The risk is arriving at DSCG level or the placement with technical gaps in French accounting that the master's curriculum did not address. The shortening of the route does not compensate for a fragile foundation.

The career-changer#

Retraining into expertise comptable is possible but requires an honest assessment. The critical variable is not intelligence or motivation — it is the capacity to sustain the required effort over several years, often alongside an existing professional activity. A well-prepared retraining — with a realistic equivalence audit, a carefully chosen apprenticeship employer, and a credible timeline — can succeed. An improvised retraining often runs out of momentum before the DSCG.

The DCG, DSCG and DEC programmes train well for technical competence. They prepare less explicitly for several dimensions of practice that make a material difference in day-to-day professional life.

An expert-comptable works in sustained contact with business owners. They must understand the client's business model, read financial statements through a simultaneously technical and strategic lens, anticipate risks, formulate clear recommendations, and stand behind their professional opinion. It is a profession of synthesis and judgement, not only regulatory command.

Competences the academic route develops less systematically:

• Decision-oriented writing and communication: a review report or a tax note is not written the way an examination answer is structured.
• Reading warning signals in a balance sheet: the technique is taught in the classroom, but the capacity to detect anomalies is formed in real files.
• Client relationship management: guiding a business owner through a disposal, a fundraising round or a restructuring requires a posture that programmes do not directly teach.
• Professional ethics as a lived practice, beyond the examination: confidentiality, independence and AML obligations are not examination questions — they are daily operational constraints. Our article on the code de déontologie de l'expert-comptable addresses this in depth.

These points recur regularly in conversations with candidates and junior collaborators.

• Underestimating the real duration: the 8-year minimum assumes a frictionless pathway. Building in a realistic margin is wiser.
• Leaving the DEC dissertation too late: work on the subject from the second year of the placement, not the last.
• Choosing a placement employer by default: the quality of exposure during the placement has a direct impact on the practical value of the DEC at registration.
• Treating the DCG as sufficient: the DCG enables technical roles but access to the regulated profession requires the DSCG and DEC without exception.
• Underweighting the synthesis and drafting components: DSCG UE 7 (professional relations) and the DEC written assessments are frequently worked last. This is a time-allocation error.

For a fuller picture of what the diplôme d'expert-comptable enables in terms of professional practice, and what the mémoriste status involves during the placement, both articles provide precise and complementary coverage.

1. Clarify your professional objective: practice or industry, generalist or specialist, employed or partner-track? The answer shapes employer choices and specialisation decisions from the start.
2. Audit your equivalences: if you already hold a master's or grande école qualification, verify with the SIEC which exemptions you can claim before enrolling.
3. Choose apprenticeship employers carefully: identify practices with an explicit supervision policy, not simply an apprenticeship job posting.
4. Start the DEC dissertation early: the topic can be chosen from the first year of placement. Begin the bibliography, meet your dissertation supervisor, and progress in sections.
5. Build your professional network during the placement: these years are also the opportunity to gain exposure to varied engagements, different clients, and unfamiliar situations. Professional judgement is formed here.
6. Engage with professional ethics early: Ordre obligations — engagement letters, professional secrecy, AML, professional indemnity — apply from the placement in various contexts. Understanding them early prevents avoidable errors.
