FET is a free and open-source time tabling app for automatically scheduling the timetable of a school, high-school or university. FET is written in C++ using the Qt cross-platform application framework. Initially, FET stood for "Free Evolutionary Timetabling"; as it is no longer evolutionary, the E in the middle can stand for anything the user prefers.[2]
FET can operate in different modes appropriate to a variety of special circumstances. In addition to the standard "Official" timetabling mode, there is a "Mornings-Afternoons" mode suitable for use with Moroccan or Algerian school systems, a "Block planning" mode that supports planning for block timetables (commonly used in North American and International Baccalaureate schools), and a "Terms" mode suitable for use with the Finnish school system.
