NHS STP SJT: How to Reason Through Situational Judgement

The situational judgement test, or SJT, is an early longlisting stage in STP recruitment, delivered online. It is not a knowledge test. It measures judgement in work relevant situations and maps to the trainee person specification, exploring values, behaviours and professionalism. Every scenario below is an original illustration written to teach the reasoning. None of them are real test items.

The format you may see

In recent cycles the STP SJT has presented a set of hypothetical workplace scenarios, each with several response options. A common format asks you to rate each option for appropriateness on a scale, for example from very appropriate to very inappropriate. Some SJTs elsewhere use a ranking format, where you order options from best to worst. The underlying skill is the same: judging what a responsible trainee should do.

A near miss scoring approach is commonly used, meaning you earn partial credit for being close to the keyed answer rather than all or nothing.

How to reason through a rating item

Illustrative scenario: you notice a colleague about to record a result against the wrong patient sample. What is the appropriateness of each option?

Work through the principles, not your gut reaction:

• Options that protect patient safety immediately and directly tend to be most appropriate. Quietly raising it with the colleague at once usually rates highly.
• Options that delay action or pass responsibility elsewhere when you could act now tend to rate lower.
• Options that ignore the issue, or that escalate aggressively before a simple direct step, tend to rate as inappropriate.

Good judgement favours acting early, communicating respectfully, and keeping the patient at the centre.

How to reason through a ranking item

If you meet a ranking format, order options by asking which best upholds safety, honesty and teamwork. Illustrative scenario: you have made a minor error in a log. The strongest option is usually to correct it and tell the relevant person promptly. Concealing it ranks worst. Options that are honest but slow sit in the middle.

What good judgement looks like

Across formats, the attributes being assessed reflect empathy, professional integrity, working with others, and adaptability. Strong responses tend to:

• Prioritise patient safety and honesty over personal convenience.
• Seek to understand a colleague's or patient's perspective before reacting.
• Act within your role and escalate appropriately, neither ignoring problems nor overreacting.
• Stay calm and constructive under pressure.

How to prepare honestly

You cannot memorise answers, and you should not try. Instead, read the person specification and the professional standards expected of healthcare scientists, then practise applying them to varied scenarios so your instinct aligns with what the role requires.
