This trainer's guide is intended to assist supervisors of work-based career training projects in familiarizing students with different types of radio paging systems (bleepers) that are used in departments where staff spend a considerable amount of time out of the office. The guide is one in a series of core curriculum modules that is intended for use in combination on- and off-the-job programs to familiarize youth with the skills, knowledge, and attitudes necessary for success in the workplace. Included in the guide are the following components: project information, a summary of the content and approach of the guide, supervisor's notes, off-the-job tutor's notes, background information, lists of tasks and core skills, an action plan that includes suggested learning activities, supervisor and trainee review sheets, and an assessment form.
