C.T.S.G. Alembic has many committees in which students can develop themselves. Most committees organise educative or sociable activities. Such activities include: excursions, sport tournaments, drinks and lunchlectures. Other committees support the association or her members. The Automatisering-, Service- en Onderhoudscommissie (ASO) is responsible for the ICT maintenance and the Onderwijscommissie (OCie) works on improving the educational programme.
Some committees organise 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 organise, national activities, such as the OSTS case tour.
