The 2026 PTCE blueprint, domain by domain

The PTCE covers four domains: Medications at 35%, Patient Safety and Quality Assurance at 23.75%, Order Entry and Processing at 22.50%, and Federal Requirements at 18.75%. You get 90 questions in 110 minutes, of which 80 are scored, and the result is reported on a 1000 to 1600 scale with 1400 to pass.

Published August 22, 2026

Every claim on this page comes from PTCB's PTCE Content Outline effective January 6, 2026. Where we are inferring something rather than quoting it, we say so in the sentence.

The format

• 90 questions total, of which 80 count toward your score
• 10 unscored pretest questions, mixed in and not identified
• 110 minutes, four options per question, one best answer
• Reported on a 1000 to 1600 scale, and 1400 passes

The 10 unscored questions matter less than people fear. You cannot pick them out, so the only rational strategy is to answer everything as though it counts. It does mean a raw percentage on a practice test is not the same measure as a scaled score, and any product that hands you a 1000 to 1600 number from a practice set is estimating rather than reproducing PTCB's curve, ours included, which is the reason we label our own number a projection rather than a score.

How the four domains split

The third column is arithmetic on the published percentages, not a PTCB figure. PTCB publishes the percentage and the knowledge areas; it does not publish a question count per domain.

Medications, 35%

Eight knowledge areas, and the largest single body of material on the exam. It covers generic and brand names with classifications, therapeutic duplications, interactions and contraindications, strengths and dosage forms and routes, side effects and allergies, indications, drug stability, and proper storage. Two of those areas are flagged in the outline as involving calculations.

The top drugs by generic name, brand name, and class are the highest-return study target on the whole exam, because the same knowledge answers questions in several of these areas at once. Our drug reference covers 212 of them free.

Patient Safety and Quality Assurance, 23.75%

Six areas: high-alert and look-alike or sound-alike medications, error prevention strategies, issues that require pharmacist intervention, event reporting procedures, types of prescription errors, and infection prevention with cleaning standards. Tall man lettering, leading and trailing zeros, barcode use, MedWatch, and root cause analysis all sit here.

The area worth extra attention is the one about pharmacist intervention, because it is the domain's clearest scope-of-practice test. A technician recognizes that a drug utilization review flag, an adverse drug event, or a request for an over-the-counter recommendation belongs to the pharmacist, and hands it over.

Order Entry and Processing, 22.50%

Four areas, all four flagged as involving calculations: formulas and conversions and sig codes, equipment and supplies for drug administration, lot numbers and expiration dates and NDC numbers, and procedures for returning dispensable, non-dispensable, and expired stock. This is the smallest number of areas of any domain and the densest arithmetic.

Sig codes carry more weight than their space in a textbook suggests, because they appear inside questions across the whole exam rather than only in their own area. The free formula sheet and glossary both cover this ground.

Federal Requirements, 18.75%

Six areas: storage and handling and disposal of hazardous and non-hazardous substances, controlled substance prescription requirements and DEA schedules, receiving and ordering and returning and destroying controlled substances, restricted drug programs including REMS, FDA recall requirements, and the Drug Supply Chain Security Act.

This domain grew substantially under the 2026 outline, from 12.50% to 18.75%. It is also the domain that rewards memorization most reliably, because its content is rules with specific numbers rather than judgment calls. If your study plan was built against an older outline, this is where it is most out of date.

Using the blueprint to plan

The percentages are the only weighting PTCB gives you, so a study plan that ignores them is guessing. A reasonable approach is to give each domain study time in proportion to its share, then bias toward whichever domain your practice scores are weakest in. Our own question bank is balanced to these weights, and the readiness score weights each domain the same way the exam does. You can read exactly how that math works in the FAQ.
