29.Section 19 defines the contracts of employment to which duties in this Chapter apply. These are contracts with a duration of more than eight weeks and which include more than 20 hours work per week. Section 20 explains what counts as making appropriate arrangements. A person has made appropriate arrangements if he or she has enrolled on a course or courses constituting relevant education or training (defined in section 6), or arrangements have otherwise been made for him or her to receive relevant education or training, or if he or she is participating in full-time education or training. A person does not need to have enrolled for sufficient (that is, enough hours in the relevant period) relevant education or training in order to count as having made appropriate arrangements. For example, he or she may be waiting for a course to end before enrolling on another.
