ADP Task Preparation

This course guides students through the five required tasks for the Adult Diploma Program (ADP). Each task is a project demonstrating the skills needed to function and progress in daily living situations. Reading a map, researching an historical fact and composing a research paper, topical health awareness, researching occupations, writing a resume, and applying to a postsecondary college or program are examples of task requirements. Each completed task is evaluated by the teacher/assessor and students must demonstrate a working understanding of the finished task. Sixty-four generalized life skill competencies are grouped into the following task areas: the community and beyond; financial literacy and numeracy; health and science; history and social science; next steps -- college and career readiness. With an instructor's guidance, students work individually and in small groups to research, study, and collect information necessary to complete the tasks.
