Since the 2015-2016 school year, teaching time for secondary education has applied to each course. The school sets its own timetable. The standard hours for secondary education are:
'Teaching time' means guided instruction that is part of the curriculum planned by the school and compulsory for all students. Furthermore, the various activities must be carried out under the responsibility of a teacher competent to do so. The school's policy is to provide students with lessons with a teacher in front of the class whenever possible.
The Lorentz Casimir Lyceum has programmed 32 to 34 weekly lessons for all students in junior high. The lessons that drop out due to absence of a teacher are called Z-hours, these lessons are taken care of by a colleague. In addition, in the bridge class one hour is scheduled for an Auxiliary Lesson or Remedial Teaching.
