This book was written over a 10-year period for, and with, university students taking a clinically-orientedpractice course in a number of human services settings, broadly defined. As such, the text may be useful to counseling, psychology, social work, criminal justice, and other types of human services majors taking their first experientially-based internship, practicum, or “service learning” class. Of course, we realize that there are differences between the course structure for internship and practicum courses that depend onsuch things as major, college, and state requirements. Therefore, it is helpful to begin by defining how weare using these and other terms and concepts that are important in this book.
