HSPA no longer offers an Instructor's Guide with the textbooks. There were several reasons for the move away from a dedicated Instructor's Guide. Major factors in the decision included: the wide variety of types of courses held; differing student needs and methods of delivery; the move away from using only HSPA materials to prepare for an exam and recent incidents of Internet piracy. Those teaching a course should assess their students' needs and develop materials that best meet those needs.
