Before the start of each course, we ask participants to fill in a form and send this to the trainer. This helps the trainer to obtain insight in to the learning goals and expectations of the participants. For participants, this a good way to prepare for asking the questions and discussing the topics that would benefit them most.
In addition, the majority of courses invite participants to bring in materials (such as a case study), or to prepare for sessions by watching/reading some online self-study materials. For a complete course, the total preparation time will be approximately 1 hour.
Courses that consist of more than one session, will often require some additional between-session work, in the form of an assignment. Assignments offer you the opportunity to put what you have learned into practice. How much time you spend on an assignment is largely up to you, although a reasonable estimate would be 1 hour for the entire course.
