Amending an apprenticeship contract: when and how

An employer changes legal status, an apprenticeship supervisor leaves the company, an apprentice fails their exam and must retake it the following year: in every one of these cases, the apprenticeship contract signed at the start of the cycle no longer matches reality. For a CFA (apprenticeship training centre), recognising these situations — and triggering an amendment at the right time — avoids funding refusals and, in the worst cases, the outright nullity of the contract.

What French labour law says

Article D. 6224-5 of the Labour Code is the legal basis to know: any change to an essential element of the apprenticeship contract requires an amendment. “Essential element” is not a vague notion left to individual judgment — administrative practice and case law have drawn a fairly stable perimeter around it.

The following are considered essential elements:

• The employer — change of the company’s legal status, takeover by another entity;
• The apprenticeship supervisor (maître d’apprentissage) — replacement during the contract;
• The qualification or diploma being prepared — redirecting the apprentice toward a different title or diploma;
• The contract’s duration and dates — extension, notably after a failed exam;
• Remuneration, when it changes outside the automatic revaluation tied to age or progression through the cycle;
• The place where the contract is performed, if it changes outside the geographic area initially set;
• The training location, if the apprentice changes CFA or training site.

A minor change — an email address, a phone number — does not justify an amendment. It is the “essential” nature of the element being changed, and its impact on the balance of the contract, that triggers the obligation.

The special case of changing the apprenticeship supervisor

This is the most frequent situation mid-cycle, and the one carrying the most legal risk. The apprenticeship supervisor is not a mere technical overseer: their professional skills and moral guarantees are a condition for the contract’s own approval. A replacement — leaving the company, changing role, extended unavailability — therefore changes a constitutive element of the contract, unless the original contract already provided for a two-supervisor tutoring team identified at signature.

Failing to formalise this carries a heavy consequence: case law has already held that the absence of an amendment documenting a change of apprenticeship supervisor could result in the nullity of the apprenticeship contract. For a CFA, this is a direct risk to training funding and to the security of the apprentice’s path — which is why it pays to systematically track, in every apprentice’s file, the identity of the current apprenticeship supervisor and any change reported by the company. Our article on apprenticeship supervisor requirements and duties details the competence and moral guarantees to check when a supervisor is replaced.

Extension after a failed exam

The second frequent case: the apprentice does not obtain their diploma or title at the end of the cycle. The law allows the contract to be extended by up to one year, on justified grounds, so the apprentice can sit the exam again. This extension mechanically changes the contract’s end date — an essential element — and therefore also requires an amendment, drawn up before the original end date rather than under the pressure of exam results.

For a CFA, the right reflex is to anticipate: as soon as an unfavourable exam result is known, start the conversation with the employer about continuing the contract, rather than waiting until the original end date passes with no formalised solution.

Signatures, visa and submission: the procedure

The amendment follows the same formal logic as the original contract. It is drawn up on the same dedicated Cerfa form (the “amendment” box checked, with the original contract’s reference number), and it must capture what changes while leaving unchanged what does not.

On signatures: the employer and the apprentice sign the amendment, exactly as they signed the original contract — with, for a minor apprentice, the co-signature of their legal representative. The CFA applies its visa to the document to validate the training-related information, but is not, strictly speaking, a signatory of the contract.

On deadlines, the Labour Code requires submission to the OPCO within 5 business days of the start of performance for an original contract (article D. 6224-1). In practice, OPCOs handle amendments with the same expectation of responsiveness: the earlier the amendment is submitted, the more secure the continuity of funding, with no risk of a payment gap while it is being processed.

What a CFA risks by neglecting amendments

Beyond the legal risk of nullity when a change of apprenticeship supervisor is not formalised, an apprentice file whose contract no longer reflects reality — wrong employer, wrong end date, wrong target diploma — is exposed to a refusal or suspension of OPCO funding. It is also a point of attention in a Qualiopi audit: consistency between the contract, the training programme followed, and the evidence of coordination with the company, checked under indicator 18, is something an auditor can verify on a sample of files. An unregularised contract also weakens the evidence expected under indicator 15 on apprentices’ rights and duties.

An unplanned termination is a distinct case from an amendment: our article on the apprenticeship contract termination procedure details the CFA’s obligations when a contract ends rather than being modified.

The human side, not just the paperwork

A doctoral thesis defended in 2018 at Université Lyon 2 by Marine Peycelon, Devenir maître d’apprentissage: configurations et affordances pour construire sa pratique tutorale en entreprise (“Becoming an apprenticeship supervisor: configurations and affordances for building a tutoring practice in the workplace”), shows that the quality of workplace tutoring is still largely built on the job, with initial training for apprenticeship supervisors often limited. This reinforces the case, for a CFA, for not treating a change of supervisor as a mere administrative formality: it is also a chance to check that the new tutor has the conditions to properly guide the apprentice, not just to update a Cerfa form.

Take action

Tracking amendments as they happen, rather than discovering an outdated file at audit time, is one of the reflexes a well-built quality system installs naturally. The Complete Kit Certif (€297, 14-day guarantee, documents in French) provides procedures and tracking tables adapted to CFA specifics, including indicators 18 and 15.
