C.T.S.G. Alembic has many committees in which students can develop themselves. Most committees organize educative or sociable activities. Such activities include excursions, sports tournaments, drinks, and lunch lectures. Other committees support the association or her members. The “Automatisering-, Service- en Onderhoudscommissie” (ASO) is responsible for the ICT maintenance and the Education Committee (EduCo) works on improving the educational programme.
Some committees organize activities that are of great importance to the association. For example, a yearly study trip is organized to countries outside of Europe. Examples of these locations include Argentina, Malaysia, and Japan. Besides that, Alembic finds it important to take part in, or organize, national activities, such as the OSTS case tour.
