Passing the Prescribing Safety Assessment (PSA) is not about memorising every drug in the BNF. The most successful candidates develop a systematic approach to safe prescribing, learn how to use available resources efficiently, and practise applying their knowledge under realistic exam conditions. The PSA is designed to assess prescribing competency across a range of clinical scenarios and specialties, reflecting the decisions newly qualified doctors make every day.
Before diving into revision, take time to understand exactly what the PSA assesses. The examination evaluates eight key prescribing competencies:
Prescribing
Prescription Review
Planning Management
Providing Information
Calculation Skills
Adverse Drug Reactions
Drug Monitoring
Data Interpretation
Understanding the purpose of each question type allows you to tailor your revision and avoid wasting time on low-yield activities. The assessment is designed to evaluate safe and effective prescribing rather than simple factual recall.
How to Pass the PSA First Time | Prescribing Safety Assessment Revision Guide
One of the biggest differences between students who struggle and students who excel is their ability to navigate the BNF efficiently. The BNF is available during the assessment because real-world prescribing is not a memory test. However, simply having access to the BNF is not enough. You must know where information is located and how to retrieve it quickly under pressure. Spend time becoming familiar with:
Antibiotic guidance
Anticoagulants
Diabetes treatments
Insulin products
Opioid conversions
Fluid prescribing
Drug monitoring advice
Every minute saved searching allows more time for clinical decision-making.
Many students revise by reading notes for hours. Unfortunately, the PSA rewards application rather than passive learning. The best preparation involves completing realistic exam-style questions in the same format as the actual assessment. This develops familiarity with question wording, common prescribing challenges, and the pace required to perform well. Dedicated PSA resources and official preparation materials emphasise repeated exposure to authentic question styles. When practising, don't just check the answer. Ask yourself:
Why was this the safest option?
What prescribing principle was being assessed?
What information should have alerted me?
This is where real learning occurs.
Certain topics appear repeatedly because they are associated with medication errors and patient safety. These include:
Fluid prescribing
Anticoagulants
Insulin
Controlled drugs
Opioids
Renal impairment
Drug interactions
Monitoring requirements
These areas are worth revisiting multiple times during your revision because they underpin many prescribing decisions seen within the PSA.
The PSA is as much a test of efficiency as it is a test of knowledge. Many students lose marks because they spend too long trying to perfect a single answer. Successful candidates understand that every question contributes to the overall score and that time must be distributed wisely across the paper. Guidance from major PSA preparation resources consistently highlights time management as a critical factor in success. A useful rule is: Identify → Decide → Move On. Do not become trapped in lengthy searches or overthinking.
Mistakes are one of the most powerful revision tools available. Create an error log containing:
The topic tested
Your incorrect answer
The reason it was incorrect
The correct approach
Relevant BNF references
Over time you will identify patterns in your performance. Most students discover they repeatedly struggle with specific areas such as calculations, prescription review, or data interpretation. Recognising these weaknesses early allows targeted improvement.
The final week before the PSA should focus on refinement rather than panic revision. Prioritise:
✅ Timed practice sessions
✅ BNF navigation
✅ Fluid prescribing
✅ Calculation skills
✅ Prescription review questions
✅ Common medication safety issues
At this stage, confidence comes from repetition and familiarity. Trust the work you have already completed and focus on applying safe prescribing principles consistently.
Effective PSA preparation combines prescribing knowledge, medication safety awareness and structured exam practice.
Students who pass the PSA first time are not necessarily the students with the best memory. More often, they are the students who understand the assessment, navigate the BNF efficiently, practise realistic questions regularly, and manage their time effectively.
Master the process, trust the principles of safe prescribing, and approach each question logically. Do that consistently, and you'll place yourself in a strong position to succeed in the Prescribing Safety Assessment the first time around.
