What's on the PTCB Exam? 2026 PTCE Content Outline Explained

Four domains, current weights, no mystery fifth section

People search “what is on the PTCB exam” and land on tables that still list compounding or outdated percentages. The live job is the PTCE Content Outline effective January 6, 2026. Practice those four current PTCE domains in Passy → instead of memorizing a competitor’s older map.

PTCB kept four domains and the same test length after its 2024 job analysis. It changed what sits inside those domains and how much each one counts.

Domain 1 — Medications (35%)

This is the largest domain. The outline asks for generic and brand names, classifications, therapeutic duplications, interactions and contraindications, strengths and doses, dosage forms and routes, handling and duration, side effects and allergies, indications, and stability and storage. Some of those statements are calculation-based.

It does not publish a fixed official “Top 200” roster. PTCB Medications is the study map. Do you need the Top 200? corrects the list myth.

Domain 2 — Federal Requirements (18.75%)

Federal—not state—rules: hazardous and P-list waste, controlled-substance prescriptions and DEA schedules, receiving and storage and take-back and loss, restricted programs such as pseudoephedrine and REMS, FDA recalls, and DSCSA serialization, tracking, tracing, handling, and quarantining. Some statements are calculation-based.

PTCB Federal Requirements walks the knowledge areas. State technician registration is a separate legal question. PTCB’s CPhT page says legal scope is defined by State Boards of Pharmacy.

Domain 3 — Patient Safety and Quality Assurance (23.75%)

High-alert and look-alike/sound-alike medications, error-prevention methods, pharmacist intervention (DUR, ADE, OTC), event reporting (including MedWatch, VAERS, RCA, CQI), prescription errors, and infection prevention and PPE. Several statements include calculation-based knowledge.

Patient Safety & Quality Assurance is the domain page.

Domain 4 — Order Entry and Processing (22.50%)

Formulas, calculations, ratios, proportions, conversions, Sig codes, abbreviations, days supply, quantity, dose, concentration, dilutions, administration supplies, lot numbers, expiration dates, NDC numbers, and procedures for returns and reverse distribution. This is where most of the visible math lives.

Order Entry & Processing covers workflow identifiers. PTCB pharmacy math works original setups. Put current order-entry and calculation items into mixed PTCE practice in Passy → after you can name those knowledge areas without looking.

What is not a current PTCE domain

PTCB’s job-analysis notice removed nonsterile compounding content and alligations, and it removed the dedicated NTI knowledge area. Those deletions are the job of PTCB exam changes in 2026. This page stays on what remains.

The exam itself is 90 multiple-choice questions, 80 scored, with four options and one best answer. That count lives on How many questions are on the PTCB exam?.
