OPRA vs KAPS Exam: Key Differences Explained (2026)

The OPRA vs KAPS exam comparison is important for overseas-qualified pharmacists preparing for registration in Australia. In March 2025, the Australian Pharmacy Council (APC) replaced the Knowledge Assessment of Pharmaceutical Sciences (KAPS) examination with the Overseas Pharmacist Readiness Assessment (OPRA).

This change introduced a shorter examination, revised content areas, a stronger focus on therapeutics, and updated methods for selecting and scoring questions.

But what exactly changed? Is the OPRA exam more difficult than KAPS? Can candidates still use their previous KAPS results?

This guide explains the key differences between OPRA and KAPS, their examination patterns, syllabus coverage, scoring systems, and what candidates should know before preparing for OPRA in 2026.

What Is the Difference Between OPRA and KAPS?

The main difference between OPRA and KAPS is the examination structure and assessment approach.

KAPS was the previous assessment used in the relevant Australian Pharmacy Council Knowledge Stream. It consisted of two examination papers assessing pharmaceutical sciences.

OPRA replaced this system with a single 120-question examination completed within 150 minutes.

The redesign also introduced revised content specifications and an evidence-based psychometric scoring approach.

On 31 July 2024, the Australian Pharmacy Council announced plans to redesign KAPS and introduce OPRA from March 2025.

The change followed a review of examination specifications and contemporary assessment practices.

APC identified several priorities:

1. Updated Examination Content

The revised content specifications place greater emphasis on therapeutics and the application of pharmaceutical knowledge.

This reflects the importance of understanding medicines, their effects, and appropriate use in patient care.

2. Shorter Examination Duration

OPRA reduced the total examination time from four hours across two KAPS papers to 150 minutes in one examination.

3. Revised Question Selection and Scoring

APC introduced the Rasch psychometric model to support consistent assessment standards across different examination forms.

This methodology helps evaluate examination performance while accounting for differences in question characteristics.

4. A More Targeted Assessment

The updated structure assesses biomedical sciences, medicinal chemistry, biopharmaceutics, pharmacokinetics, pharmacodynamics, pharmacology, toxicology, and therapeutics through five published content areas.

The OPRA examination is a closed-book, computer-based assessment conducted at approved test centres.

Its current examination structure is:

• Total questions: 120 multiple-choice questions

• Examination duration: 150 minutes

• Options per question: Four

• Correct answers: One per question

• Examination content areas: Five

• Examination authority: Australian Pharmacy Council

Candidates have an average of 75 seconds per question.

The assessment is not divided into Paper 1 and Paper 2.

One of the most important changes is the updated syllabus structure.

According to APC, the OPRA examination covers five content areas.

Biomedical Sciences – 20%

Candidates should understand human physiology, pathophysiology, microbiology, immunology, and the mechanisms of disease.

Medicinal Chemistry and Biopharmaceutics – 10%

This area includes physicochemical drug properties, dosage forms, pharmaceutical stability, solubility, dissolution, and drug delivery.

Pharmacokinetics and Pharmacodynamics – 10%

Relevant topics include absorption, distribution, metabolism, elimination, clearance, half-life, steady-state concentrations, drug interactions, and pharmacokinetic calculations.

Pharmacology and Toxicology – 15%

Candidates are assessed on drug mechanisms of action, receptor pharmacology, adverse reactions, interactions, toxicity, and antidotes.

Therapeutics and Patient Care – 45%

This is the largest examination content area. It includes the application of pharmaceutical knowledge to treatment selection, medicine safety, patient monitoring, dose calculations, and medicine use in different patient populations.

Important: The 45% weightage of Therapeutics and Patient Care does not mean the other scientific subjects can be ignored. All five areas contribute to overall examination performance.

Yes. Contrary to a common misconception, OPRA does not eliminate recall-based questions.

APC publishes the following approximate cognitive-level distribution:

This means preparation should include factual revision, conceptual understanding, and the ability to apply knowledge.

Candidates should not rely solely on clinical cases or complex problem-solving exercises.

There is no reliable basis for claiming that OPRA is universally easier or harder than KAPS.

The examinations differ in their formats, content specifications, and assessment methodologies. Difficulty also depends on a candidate's educational background, pharmaceutical knowledge, examination preparation, and familiarity with the subjects.

OPRA has a shorter testing duration, but its revised content structure requires preparation across all five areas.

Candidates who previously studied for KAPS may already understand many relevant pharmaceutical concepts. However, they should review the current OPRA syllabus and identify topics requiring additional preparation.

OPRA uses an evidence-based scaled scoring system.

The APC assesses whether a candidate meets the overall examination passing standard rather than ranking candidates against one another.

Of the 120 OPRA questions, approximately 90% are scored and 10% are unscored questions used for examination development and calibration.

Candidates are not told which questions are unscored.

APC does not disclose individual raw examination percentages.

The result report indicates whether the candidate met the examination standard or was unsuccessful. Content-area feedback is provided for general development, but individual content-area performance does not independently determine the final result.

Some KAPS preparation materials may remain useful for revising foundational pharmaceutical sciences.

Topics such as pharmacology, physiology, medicinal chemistry, drug interactions, and pharmacokinetics overlap with the knowledge relevant to OPRA.

However, older resources may not reflect the current OPRA examination specifications.

Candidates should:

1. Review the current OPRA syllabus published by APC.

2. Identify areas not adequately addressed by existing materials.

3. Use current pharmaceutical science textbooks and evidence-based learning resources.

4. Practise relevant multiple-choice questions.

5. Include therapeutics, patient care, and pharmaceutical calculations in their study plans.

APC does not endorse particular commercial preparation programs or external textbooks.

Candidates who successfully completed the previous KAPS examination may still be able to progress through the applicable Australian pharmacist registration pathway.

The transition from KAPS to OPRA did not automatically invalidate successful KAPS results.

However, candidates must satisfy the current requirements of the relevant regulatory authorities.

Candidates should consult APC and the Pharmacy Board of Australia regarding the acceptance of previous examination results and any applicable registration timeframes.

What if I Passed Only One KAPS Paper?

APC clarified during the transition that a candidate who passed only one KAPS paper but had not completed both papers before KAPS ended would need to sit the new OPRA examination.

An individual KAPS paper pass cannot be combined with an OPRA result to complete the examination requirement.

Step 1: Understand the Current Syllabus

Review the five official content areas and their approximate weightages.

Step 2: Identify Your Knowledge Gaps

Use practice questions to evaluate your understanding of pharmaceutical sciences and therapeutics.

Step 3: Revise Core Concepts

Study pharmacology, biomedical sciences, medicinal chemistry, pharmacokinetics, and pharmaceutics.

Step 4: Practise Pharmaceutical Calculations

Include dose calculations, concentration and dilution, infusion rates, and pharmacokinetic calculations.

Step 5: Practise Questions Under Timed Conditions

Use the official duration of 150 minutes for 120 questions when undertaking full-length mock examinations.

Step 6: Review Incorrect Answers

Analyse your mistakes to identify subjects requiring additional revision.
