The KLE Formations difference: training built around practice
A running project throughout the programme, from the very first modules, lets you both absorb what you learn in class and gradually build a complete project inspired by a real business challenge.
It is this progressively built project that forms the basis of the final defence before the jury.

Support and follow-up after the programme
Far more than a training provider: individual follow-up for 1 to 6 months to embed your learning and consolidate your skills within the company.
Our commitment to quality
A quality commitment recognised by Qualiopi certification, compliant with the French National Quality Framework.

Funding
Retraining or upskilling has a cost - but rarely one you bear alone. Several schemes can step in and, in most cases, they can be combined.
The principle: your status determines your entitlements
No funding is automatic. The right scheme depends above all on your situation (employee, jobseeker, self-employed, public sector worker). Most can be combined and cover the bulk of the cost.

Good news if you’re moving into these professions: KLE Formations programmes tick the right boxes.
Our programmes aim for a level 7 professional qualification and our organisation is Qualiopi-certified, which opens access to vocational training funding schemes.
Do I have what it takes to become Data Engineer ?
Tick what sounds like you. No commitment - motivation matters as much as your starting point.

A conversation with an adviser will help you see more clearly - many people start from scratch.
Frequently asked questions
It is designed for people changing careers, junior IT profiles and jobseekers who want to move into the field. The programme alternates targeted theory, guided workshops, realistic scenarios and team exercises, to build genuine professional reflexes - not just another line on a CV.
No, but you need to be comfortable with a computer, curious, rigorous and ready to work intensively. We start with the fundamentals before moving on to more advanced scenarios.
The programme is designed for employability (professional project, capstone, targeted career opportunities), but no job can be guaranteed: the outcome depends on your attendance, your progress and the state of the market. Our teams support you in your job search.
Get in touch describing your background and your situation (CPF, France Travail, OPCO, Transitions Pro…). An adviser will check your eligibility and work out your remaining cost with you, subject to conditions.
