Based on police training guidance and rookie‑officer studies, there are a few recurring mistakes almost every new recruit tends to make. Here are the main five, grouped from the most consistently cited issues:
1. Overconfidence / “Know‑it‑all” attitude
Many recruits come in thinking they already understand policing, especially if they have related experience.
This can block learning and frustrate instructors, it often leads to ignoring guidance, shortcuts, or poor decisions early on.
Better approach: Stay humble and treat the first few years as a learning phase. In fact you actually never stop learning, you may get proficient in the job but you can learn something new every day.
2. Not asking questions or seeking help, New officers sometimes try to impress by acting independent too early.
Failure to ask questions during training slows learning and increases mistakes, avoiding mentorship can lead to poor judgment and stress.
A better approach is to ask questions constantly, training is the safest time to learn. But, be aware of current sensitivities to diversity and inclusion issues, the police have over invested in this area in an attempt to placate the vocal minority, so avoid getting embroiled in arguments in this area. One day we might return to a system which treats everyone equally which should be less divisive than current policy and protocols. When you swear you oath you will promise to treat people ‘without fear or favour’ and that is a good promise to remember even if some in government and the college of policing seem to have forgotten.
3. Poor emotional control under pressure
Policing is high-stress, and rookies often struggle with this adjustment.
Some recruits react emotionally to criticism or stressful situations
Difficulty staying calm can affect communication, decision-making, and safety
Better approach: Develop emotional resilience and stay composed during feedback and incidents.
4. Weak communication and people skills, technical skills matter, but communication is often where rookies struggle most.
Misreading people or using the wrong tone can escalate situations, over‑assertiveness or hesitation can both damage public trust.
The better approach is to focus on clear, calm communication and rapport-building. Remember, these days you will often be filmed by one or more people when you are working and they can often be very selective with what they post on social media. Bear this in mind with everything you say and do. If you are not sure of something do not be tempted to just make something up, auditors out there will catch you out and currently the system often fails to support you when this happens.
5. Poor discipline (time management, instructions, and detail) Small lapses add up quickly in training and on the job.
Failing to follow instructions precisely or manage time well is a common cause of failure.
Missing details (e.g., reports, procedures) can lead to serious consequences as ‘the job’ is quick to punish rather than support officers these days unfortunately.
The better approach is to be highly organized, detail-focused, and disciplined.
Integrity lapses (even minor ones) can end a career early, the police are under immense pressure from some of the public and the mainstream media, and senior officers tend to side with that pressure rather than support their officers, resulting in minor transgressions being dealt with disproportionately. Overusing authority instead of building respect can also escalate situations.
In simple terms, most rookie mistakes come down to:
Ego
Inexperience under pressure
Communication gaps
Lack of discipline
Not using support systems (for fear of being criticized or punished)
