How many questions can you miss on the PTCE?

There is no fixed number. Because results are scaled, the number of correct answers needed to reach 1400 varies slightly between exam versions.

Is the PTCE multiple choice?

Yes. Every question is multiple choice with four options and one correct answer.

PTCE Exam Format & Scoring Explained (2026)

How many questions are on the PTCE?

The Pharmacy Technician Certification Exam (PTCE) has 90 multiple-choice questions. Only 80 are scored. The other 10 are unscored pretest questions that PTCB is trying out for future exams. They are mixed in with the scored questions and look exactly the same, so treat every question as if it counts.

Each question has four answer options and one correct answer.

How long is the PTCE?

You have 1 hour 50 minutes (110 minutes) to answer all 90 questions — a little over a minute per question. Plan for about two hours at the test center or online session in total, including the tutorial and a short survey.

Pacing tip: aim to reach question 45 with at least 55 minutes left. Flag anything that takes longer than 90 seconds and come back to it.

What does the PTCE cover?

The 2026 content outline has four domains:

Medications — 35% (about 28 scored questions): brand and generic names, drug classes, interactions, dosage forms, side effects, storage, and narrow therapeutic index drugs.
Patient Safety and Quality Assurance — 23.75% (about 19): high-alert and look-alike/sound-alike drugs, error prevention, event reporting, and when to involve the pharmacist.
Order Entry and Processing — 22.5% (about 18): interpreting prescriptions, pharmacy calculations, days supply, NDC numbers, lot numbers and expiration dates.
Federal Requirements — 18.75% (about 15): controlled substances and DEA forms, REMS programs, recalls and the Drug Supply Chain Security Act (DSCSA).

How is the PTCE scored?

Your raw score (the number of scored questions you get right) is converted to a scaled score from 1000 to 1600. A scaled score of 1400 is required to pass. Scaling keeps results fair across different versions of the exam, so you don't need a fixed percentage correct.

There is no penalty for guessing — never leave a question blank.

What changed on the 2026 PTCE?

Federal Requirements grew from 12.5% to 18.75% and now includes the DSCSA.
Order Entry and Processing rose slightly to 22.5%.
Medications dropped from 40% to 35%; Patient Safety and Quality Assurance dropped to 23.75%.
Sterile and non-sterile compounding were removed.

If you're using older study material, spend extra time on federal law — it's now worth almost a fifth of the exam.

How to use the format to prepare

Take a free PTCE diagnostic test to see your score by domain.
Spend study time roughly in proportion to the domain weights, starting with your weakest area.
Finish with at least one full-length, timed practice exam so 110 minutes feels normal.
