The PTCB exam is considered moderately difficult but is passable with proper preparation. It consists of 90 multiple-choice questions covering four domains: Medications (40%), Patient Safety & Quality Assurance (26.25%), Order Entry & Processing (21.25%), and Federal Requirements (12.5%). The exam tests not only factual recall but also the ability to apply knowledge in real-world pharmacy scenarios.
National pass rates have hovered around 70–75% in recent years, indicating that most candidates succeed on their first attempt. However, many find the breadth of content challenging, especially topics like drug names, dosage calculations, and regulatory compliance. Time pressure can also be a factor, as test-takers have just 110 minutes to complete the scored portion.
Success is more likely for those who complete a PTCB-recognized training program or have hands-on experience. Effective preparation includes using official PTCB practice tools, mastering the top 200 drugs, and taking full-length timed practice exams. According to student reports, consistent study over 4–8 weeks significantly boosts confidence and performance.
While the exam is demanding, it is designed to be fair and reflective of entry-level competence. With focused study and realistic practice, most candidates can pass the PTCB exam and earn their CPhT credential.
