If you are targeting a work-study placement in a large company, there is an often overlooked lever working in your favour: the 5% work-study threshold. Companies with 250 or more employees that stay below it pay an additional contribution, and this same threshold now also governs the apprentice hiring incentive paid in 2026.
In short: any company with at least 250 employees that employs less than 5% work-study staff (apprentices, professionalisation contracts, CIFRE) in its average annual headcount owes the additional apprenticeship contribution (CSA), calculated on its payroll. Since 8 March 2026, these companies also only keep the hiring incentive for an apprentice if they reach 5% work-study staff (or 3% with a 10% increase) by 31 December of the following year. Large groups therefore have a direct financial interest in hiring work-study students.
Where does this 5% quota come from?
The 5% threshold is not new: it underpins the additional apprenticeship contribution (CSA), provided for in article L. 6242-1 of the French Labour Code and payable on top of the apprenticeship tax. It is neither a ban nor a hiring obligation, but a financial incentive: the more work-study staff a company has, the less it pays.
"The fewer young people on work-study contracts a company employs […], the more it pays." — Service-Public Entreprendre, "Contribution supplémentaire à l'apprentissage" factsheet
Here is the CSA scale, applied to payroll (outside Alsace-Moselle, where the rates are reduced):
| Share of work-study staff in the workforce | CSA rate |
|---|---|
| Less than 1% (250 to 2,000 employees) | 0.4% |
| Less than 1% (more than 2,000 employees) | 0.6% |
| From 1% to less than 2% | 0.2% |
| From 2% to less than 3% | 0.1% |
| From 3% to less than 5% | 0.05% |
| 5% and above | Exempt |
The company is also exempt if it has at least 3% work-study staff and has increased their number by at least 10% compared with the previous year. The CSA for a given year is declared in the March DSN of the following year and collected by Urssaf (or the MSA) in April.
Who is affected and how is the rate calculated?
The CSA targets companies with at least 250 employees that are subject to the apprenticeship tax. The work-study rate compares the average annual number of work-study staff with the company's average annual headcount; Urssaf sends both figures to the employer. The numerator includes:
- apprentices;
- employees on a professionalisation contract;
- doctoral students under a CIFRE agreement (industrial agreement for training through research);
- former work-study students hired on a permanent contract (CDI), during the year following the end of their contract.
How is it linked to the 2026 hiring incentive?
Since decree no. 2026-168 of 6 March 2026, companies with 250 or more employees receive an exceptional incentive for apprenticeship contracts signed since 8 March 2026 and starting before 1 January 2027: €2,000 up to bac level, €1,500 at bac+2 level and €750 from bac+3 to bac+5 (€6,000 for an apprentice with a disability). But they must reach, by 31 December 2027:
- either 5% of contracts promoting professional integration (apprenticeship, professionalisation…) in their total annual workforce;
- or at least 3% work-study staff with a 10% increase in that number compared with 31 December 2026.
The Agence de services et de paiement (ASP) then sends them a sworn statement and checks that the targets have been met, notably via the DSN. The amounts for all company sizes are detailed in our article on the 2026 apprentice hiring incentive.
Why is this an asset for your work-study search?
For candidates, this double mechanism acts as a structural hiring lever. HR departments in large companies have a numerical target to track every year. Three concrete consequences for you:
- A direct interest in hiring. Each additional work-study student brings the company closer to the threshold that reduces or removes the CSA and secures the hiring incentive: a concrete argument to slip into your application.
- More varied profiles. To reach their rate, large groups have an interest in opening work-study beyond technical functions (finance, management control, marketing, HR, procurement…).
- A premium on unsolicited applications. Many large groups do not publish all their offers: target them directly via our job search engine or with an unsolicited application.

How to take advantage of it in practice?
The work-study rate is calculated on the average annual headcount: a contract signed at the start of the academic year counts in that year's average pro rata to its duration, then in full the following year, which is the year in which the targets linked to the incentive are assessed. Four habits to turn this mechanism into a signed contract:
- Target the large companies in your sector, even those that did not usually recruit work-study students. Check the work-study offers regularly.
- Highlight your added value: a work-study student is paid a percentage of the SMIC, benefits from contribution exemptions and represents a future hiring pool — exactly what the CSA encourages.
- Build a strong file: tailored CV, targeted cover letter, clear projection of your role in the team. Follow our guide to acing your work-study interview and our 2026 work-study CV template.
- Secure your budget: estimate your future salary with the pay simulator and activate the financial aid that tops up your pay (Mobili-Jeune, Visale guarantee, local authority aid for the driving licence).
For candidates who had not yet signed this summer, the Parcoursup supplementary phase was open until 10 September 2026; outside Parcoursup, many CFAs recruit through direct applications all year round. The 5% threshold creates a lasting window of opportunity: seize it.
