About CLL

Since its creation by the UCL in 1984, CLL has given a communicative, oral and interactive approach to language teaching. An approach based primarily upon your individual needs.

A personalised and convivial learning environment

Our aim is to provide you with exactly the right type of training programme based upon your needs, motivation and personal goals. Language training can only be truly effective if you have a real desire to learn. CLL's pedagogical approach allows you to become the protagonist of your own training

At CLL, we guarantee :

  • a warm welcome, good, sound advice and excellent service ;
  • an accurate assessment of your initial linguistic level ;
  • that your classes will be taught by highly qualified and competent trainers, who are monitored closely and who participate actively in ongoing training.

A Certified Quality

CLL is the only Belgian school accredited by Eaquals, the European association for Excellence in Language Education.

In 2017, CLL received for the sixth time the Qfor seal of approval, certifying the quality of training in our organisation. To receive this seal of approval, CLL passed the satisfaction audit for the management of its processes and resources, proof of the quality of its services

A three-way teaching approach – you, your trainer and the CLL pedagogical team

A team of 500 trainers teaching 37 languages actively pursue ongoing professional development opportunities and pool their experience to constantly develop their pedagogical techniques.

At CLL, we guarantee :

  • effective and appropriate learning methods;
  • ongoing dialogue between you, your trainers and our Pedagogical Department;
  • a certificate at the end of your course and advice for further improvement.

The criteria used to define CLL’ s quality can be found in our Quality charter.
