Methods used and modalities for evaluation

Our courses may welcome a maximum of ten attendees and the number of tutors may vary between one and two depending on the amount of practical tasks in the course.

Parameters such as the number of attendees and their overall skill level will affect pedagogical modalities such as the number of pratical tasks, guided discussions, collaborative development, etc.

Courses may include small projects to develop independently to help consolidate the acquired knowledge.

The ressources are written by the OCamlPro team prior to the courses. Documents are generally written in english and can be translated to french if need be.

We make the progress of our trainees and its evaluation a core aspect of our courses. Indeed, guaranteeing the durable acquisition of the skills at hand is key, especially for the newer comers. To that extent, we will have trainees undergo tailored group works, exercises and hands-on practice which modalities can all be customised to your specific needs.

Accessibility, handicap

Preliminary studies are done prior to every training to guarantee the quality of the course by tweaking the pedagogical modalities and take into consideration any handicap communicated during the first stages of the registration.
