ENA Cycle Moyen Supérieur common mistakes
ENA Cycle Moyen Supérieur · Understand the traps and how to avoid them.
In the note de synthèse, the candidate recopies or juxtaposes passages from the dossier in the order they appear instead of reorganising them around a problem statement and a small number of argued parts, so the note reads as a patchwork with no thesis.
Under time pressure the candidate treats the exercise as summarising each document in turn; school habits of 'one paragraph per document' survive, and the candidate has never internalised that the expected product is a decision-support note addressed to a named authority, not a literature review.
What to do instead
Before writing, spend 15 minutes building a table mapping each document to themes, then force the themes into 2-3 parts each answering an explicit question. Draft the introduction last but place it first: context sentence, problem statement (problématique) phrased as a tension, announcement of plan. Ban any sentence beginning with 'Le document 3 indique que'; every citation must be reworded and attached to an argument. Practise on a full dossier under 4-hour timing at least three times.
The candidate writes a note that exceeds the imposed page or word limit, or pads it with a long restatement of the context and a conclusion that merely repeats the plan, leaving no room for the recommendations the jury expects.
Fear of omitting a document drives accumulation; candidates also underestimate how much space the introduction consumes and do not count lines while drafting, discovering the overflow only at the end.
What to do instead
Fix a budget before writing: roughly one tenth for the introduction, three quarters for the development, one tenth for a short conclusion opening onto recommendations. Count lines every paragraph. Cut by deleting illustrative detail, not by deleting arguments. Keep a one-page reserve of unused ideas so cutting feels safe rather than lossy.
In the cas pratique, the candidate answers in general policy terms ('il faudrait renforcer les contrôles') without identifying the applicable legal norm, the competent authority, the procedure and the deadline, and without a dated action plan.
Candidates revise law as bodies of knowledge to be recited rather than as grids for resolving a situation; they also confuse the cas pratique with the note de synthèse and produce commentary instead of a decision.
What to do instead
Adopt a fixed grid applied mechanically to every case: facts, legal question, applicable texts (with article numbers), competent authority, procedure and time limits, decision, risks, implementation timetable with responsible actors. Train on short scenarios where you must name the exact text and the exact authority in the first two minutes.
On public law questions, the candidate states a rule without its source or hierarchy, confuses a law, a regulation and a circular, and cannot say which judge (administrative or constitutional) controls which act.
Revision is often done from summaries that flatten the hierarchy of norms; candidates memorise outcomes of landmark cases without the reasoning, so they cannot transfer the rule to a new fact pattern.
What to do instead
Build a one-page hierarchy chart and, for each major rule, note its source, author, and controlling judge. For each leading case, write three lines: facts, principle, scope. Test yourself by taking a current measure and asking which norm it must respect and who can annul it.
On public finance questions, the candidate mixes up the roles of the executive and Parliament in the budget cycle, cannot state the calendar of the finance bill, and treats the budget as an accounting document rather than an authorisation.
The subject is often revised late and superficially, through headlines about deficits rather than through the procedure; the distinction between authorisation, commitment and payment is never firmly acquired.
What to do instead
Draw the annual timeline from the spring framing debate to the constitutional deadline for the finance bill, marking each actor. Learn the key principles (annuality, unity, universality, sincerity, speciality) with one concrete example of a breach each. Practise explaining in 90 seconds why Parliament's authorisation matters.
In economics answers, the candidate describes an institution or a mechanism without any figures or orders of magnitude, and cannot situate France or the EU in international comparisons.
Candidates fear quoting a wrong number and therefore avoid all quantification, not realising that a jury reads absence of magnitude as absence of mastery.
What to do instead
Memorise a small, dated dashboard of about twenty figures (growth, debt and deficit ratios, unemployment, EU budget size, share of public spending in GDP) with the year and source for each. In any answer, place at least one figure and one comparison, and state explicitly when a figure is approximate.
In management public answers, the candidate imports private-sector vocabulary wholesale (client, profit, shareholder) and proposes reforms without addressing statutory constraints, staff status, or the actual levers available to a public manager.
Management is revised from business-school material that ignores the specificities of public action; candidates also want to sound modern and dynamic and overcorrect towards private-sector language.
What to do instead
For every management concept, prepare a public-sector translation: usager rather than client, performance multidimensionnelle rather than profit, autorité politique rather than shareholder. Anchor each proposal in a real lever (organisation, training, digitalisation, contractualisation, budget arbitrage) and state its legal or social feasibility.
On international and European questions, the candidate gives a chronological narrative of events without identifying the interests of the actors, the decision-making procedure at stake, or France's position and margin for manoeuvre.
Press-driven revision produces a list of facts and crises; candidates never practise the analytical move from event to actor, interest and procedure, which is what the jury is testing.
What to do instead
For each major dossier, prepare a three-column grid: actors and their interests, legal and institutional framework (which procedure, which majority), France's and the EU's leverage. Rehearse two-minute briefings on a handful of current dossiers using only that grid, updating them monthly.
During the entretien, the candidate presents a recitation of their CV or a prepared speech, ignores the jury's follow-up questions, and cannot connect their personal trajectory to the missions of the administration they are joining.
The oral is prepared as a monologue to be delivered, and stress pushes candidates to cling to the script; many have not researched the specific corps or administration and so cannot answer 'why us'.
What to do instead
Prepare a ten-minute pitch structured around three transitions (what I learned, what I can bring, why this administration), then rehearse being interrupted. Have a short file on the administration's missions, recent reforms and current challenges. Record yourself and check that you answer the question asked before adding anything.
In culture générale essays, the candidate produces a balanced but empty dissertation that surveys opinions without taking a position, and illustrates only with ready-made examples disconnected from current affairs.
The French dissertation format encourages a search for balance, and candidates mistake neutrality for rigour; they also lack a regularly refreshed stock of examples and so recycle school references.
What to do instead
Impose an explicit thesis in the introduction and defend it, using the second part to test its limits rather than to contradict it. Maintain a current-affairs log with one dated example per theme per week, each with a figure and a source. End with a clear answer to the question posed, not a summary.
