Within the TSAC several courses can be followed.

  • Courses a for climbing certification. Members can follow climbing courses and get an official climbing certification — called a "klimvaardigheidsbewijs" or "KVB" in Dutch — from the Dutch Climbing & Mountaineering Association (NKBV). These certifications are acknowledged in the Netherlands and Belgium and some climbing gyms require you to show this card before you are allowed to climb there. 

  • Training to become an instructor. For the more experienced climbers it is possible to become an (assistant) instructor or instructor trainer/examiner. When you pass your instructor exam you can get diploma and a license that is registered at the NKBV. You are only allowed to instruct if you have an active license, each year you have to renew your license by following certain refresher courses.

TNO organises the courses for the indoor climbing and rescue techniques for outdoor climbing. In the course schedule you can find the exact dates and times at which the courses are given and how to apply for them.
