NAPT case studies
NAPT · Put your knowledge to work in context.
The NAPT Professional Development Series (PDS) is the education and certification track offered by the National Association for Pupil Transportation, the school transportation industry's largest and most diverse membership organization. PDS courses are built for working pupil transportation professionals - directors, supervisors, managers, trainers, and others moving into leadership - who want structured professional development rather than a single-entry exam. The series is delivered as numbered modules, and the four covered here are PDS 204, PDS 401, PDS 505, and PDS 609, each weighted equally at 25 percent of the material. Because NAPT publishes these as scheduled courses rather than a fixed public item bank, candidates should treat each module's content as the study scope and confirm current scheduling, certification categories, and recertification requirements directly with NAPT through its Education pages, Certification FAQs, and Professional Development Series schedule. The NAPT case studies are 5 cases and about 3,050 words.
