2. Required background

The background knowledge required for a student to benefit from the course or workshop should be stated in a list of prerequisites. If particular background in basic sciences, epidemiology or environmental health is required, this should be stated explicitly. These prerequisites may be waived if the individual concerned is particularly eager to participate in the course and shows adequate aptitude. Additionally, some background reading may be required prior to acceptance onto the course. A pretest may be used to establish the student’s baseline level of knowledge.
