CO POST cheat sheet

POST certification in Colorado is governed by Title 24, Article 31, Part 1, C.R.S., and the rules of the Colorado Peace Officer Standards and Training Board; the Board sets training and certification standards, not individual agencies.

A peace officer must be POST-certified to exercise peace officer authority; the statutory definition of "peace officer" is limited to persons in specific listed positions (e.g., police officer, sheriff, undersheriff, deputy sheriff, Colorado State Patrol officer, and certain others).

Colorado uses a two-tier model: a basic certificate (provisional certification after meeting entry training requirements) and a permanent certification earned after completing the required probationary/provisional service period without disqualifying conduct.

Core statutory duties include the use of force standard (objectively reasonable, judged from the perspective of a reasonable officer on the scene), the duty to intervene to stop excessive force by another officer, and the duty to report such conduct.

Arrest authority: a peace officer may arrest without a warrant when there are reasonable grounds to believe a crime has been committed and the person to be arrested committed it; probable cause is the constitutional threshold, not mere suspicion.

Miranda warnings are required before custodial interrogation; the custody and interrogation determinations are separate, objective analyses, and volunteered statements are not the product of interrogation.

Colorado requires reporting of use-of-force incidents and imposes specific statutory duties for encounters with persons in behavioral health crisis, including referral to appropriate services rather than jail when statutory criteria are met.

Training requirements are measured in documented hours and include legal updates, de-escalation, and crisis intervention; annual in-service requirements must be met to maintain certification, and lapses can result in decertification.

Records and reporting: POST maintains certification records, and agencies must report certain misconduct, separation, and use-of-force data; failure to report can affect an officer's eligibility to remain certified.

Use-of-force analysis applies Graham v. Connor factors: severity of the crime, whether the suspect poses an immediate threat, and whether the suspect is actively resisting or attempting to evade arrest by flight.

Deadly force may be used only when the officer reasonably believes it is necessary to prevent imminent death or serious bodily injury to the officer or another person, or to prevent the escape of a suspect the officer reasonably believes poses an imminent threat of serious bodily injury.

The duty to intervene requires an officer who observes another officer using excessive force to intervene when in a position to do so, and to report the incident to a supervisor; retaliation for reporting is prohibited.

Search and seizure: a warrant requires probable cause supported by oath or affirmation; exceptions include consent, search incident to lawful arrest, exigent circumstances, plain view, and automobile exception.

Terry stop: reasonable suspicion of criminal activity permits a brief investigatory detention; a frisk requires reasonable suspicion that the person is armed and dangerous, limited to a pat-down for weapons.

Custodial interrogation requires Miranda warnings; custody is determined by whether a reasonable person would feel free to leave, and interrogation includes words or actions reasonably likely to elicit an incriminating response.

Colorado law imposes specific requirements for consent searches and limits on certain vehicle stops; officers must document the legal basis for each stop and search.

Report writing must include facts supporting each legal element, the reasonable suspicion or probable cause basis, and all uses of force; conclusory statements are insufficient to support later review.

Evidence handling requires chain-of-custody documentation from collection through disposition; breaks in the chain affect admissibility and must be documented and explained.

Crisis intervention: Colorado law requires officers to receive training on interacting with persons with behavioral health conditions and to consider diversion to treatment when statutory criteria are met.

De-escalation is a required component of training and is evaluated as part of use-of-force review; officers must use time, distance, cover, and communication when feasible before escalating force.

Implicit bias and procedural justice training are required topics; procedural justice emphasizes voice, neutrality, respect, and trustworthy motives in police-citizen interactions.

Officer wellness and peer support: POST recognizes mental health and resilience training, and agencies must provide access to critical incident support; confidentiality protections apply to peer support communications.

Ethics: officers must avoid conflicts of interest, must not use their position for personal gain, and must truthfully report all facts, including their own misconduct, in official reports.

Community policing and problem-solving are part of the POST curriculum; problem-oriented policing uses the SARA model (Scanning, Analysis, Response, Assessment).

Traffic and criminal law updates are part of continuing education; officers must know current Colorado statutes and case law affecting stops, arrests, and searches.

Documentation of training: officers must maintain records of completed training hours, and agencies must submit required training and certification data to POST within statutory timelines.

Decertification grounds include conviction of certain offenses, failure to meet training requirements, and certain misconduct findings; the Board conducts proceedings and maintains a public record of decertified officers.
