Police National Sift and OAC: Where Candidates Go Wrong

Roughly half of everyone who sits the National Sift fails it. Not because they don't know policing, and not because they're dishonest on the questionnaire. They fail because they answer as themselves today, when the test is quietly asking for someone else entirely: the best version of the officer they're going to become.

The National Sift and the Online Assessment Centre that follows it are made up of five distinct stages, each testing something different, and each with its own specific way of catching candidates out. Here's where each one goes wrong, and what to do instead.

The behavioural styles questionnaire

This is a set of statements, things like 'I am good at understanding complex concepts' or 'I am good at understanding other people's concerns', where you rate yourself from completely disagree to completely agree. The instinct most candidates have is to answer honestly and modestly, picking "slightly agree" across the board to avoid sounding arrogant. That modesty is exactly what fails people. The questionnaire isn't measuring how humble you are, it's measuring whether you present as the confident, capable officer the role needs. Answer honestly, but as the best version of your future police officer self, not the most self-effacing version of your current one.

The situational judgement test

You'll be given a policing scenario and a list of possible responses, and asked to rate each one as counterproductive, ineffective, slightly effective, effective, or very effective. The trap here is subtle: it isn't asking which response is best, it's asking you to rate every single one. Candidates who rate the options the way they'd act in their current job, rather than as the officer they're training to become, consistently score worse. The same principle from the questionnaire applies here too.

The interview, and why the questions changed

Pass the online stage and you'll face an interview built around five competencies: public service, courage, respect and empathy, taking ownership, and being innovative and open-minded. The big mistake is assuming every question will start with 'tell me about a time when', the classic rear-facing competency format. The actual questions are built from the specific behaviours inside each competency, not a generic prompt, and recent changes mean it's no longer purely rear-facing. A genuine example: instead of 'tell me about a time you've shown courage', you might get asked for a time you admitted to a mistake and took action to resolve it, which is a much narrower, more specific ask than the headline competency suggests.

The written exercise: scanning before responding

You'll be handed a crime problem set against a complex community backdrop and asked to respond. The mistake almost everyone makes is diving straight into 'here's what I'd do'. The stronger approach scans and analyses the information first, builds a working group made up of people who are connected to the community, capable, care enough to act, and willing to commit, then structures the response using a problem-solving method called SARA: scanning, analysis, response, and assessment, with actions split into short, medium, and long term, and themed around enforcement, prevention, and advocacy.

The briefing exercise: 36 minutes of talking

This stage gives you a scenario, then feeds you four questions at a time, three to four rounds deep, with the scenario evolving between rounds. You get one minute to think and three minutes to answer each question, and across the whole exercise that adds up to around 36 minutes of sustained talking. Most candidates fail simply because they've never practised holding structured answers together for that long, not because they don't know the content.

Every one of these five stages rewards the same thing: knowing the structure before you sit down, not working it out live. That is what our Police Recruitment coaching is built around, backed by a pass-or-money-back guarantee.
