DC POST · Work through your exam, one topic at a time.
The DC POST (Police Officer Standards and Training) Certification Exam is the credential candidates in the District of Columbia work toward to demonstrate entry-level readiness for a sworn law enforcement career. This page is an independent study resource for candidates preparing for that certification pathway; it is not affiliated with, endorsed by, or operated by the District of Columbia or the Metropolitan Police Department. The DC POST study guide has 8 sections and about 3,651 words.
01DC Criminal Law and Procedure
This domain tests whether you can state the elements of the District's most-charged offenses, cite the statutory authority for a warrantless arrest, and explain what happens between arrest and first appearance. DC is not a state: its criminal code is Title 22 of the DC Code, its procedure Title 23, and its local trial court is DC Superior Court.
520 words, about 3 min02Constitutional Law and Civil Rights
This domain tests whether you can apply the Fourth, Fifth, and First Amendments to street-level decisions, and whether you know the DC-specific civil rights overlay - the Human Rights Act, firearms regulation, and the limits on protest enforcement. Stop: reasonable suspicion, based on specific and articulable facts, that the person has committed, is committing, or is about to commit an offense.
478 words, about 2 min03Patrol Operations and Community Policing
This domain tests how MPD organizes patrol, how calls are prioritized and dispatched, and how community policing is actually implemented in the District rather than described in slogans. MPD operates seven districts, each divided into Police Service Areas (PSAs); the PSA is the unit of community ownership, with assigned PSA officers who are expected to know their area's people, problems, and patterns.
446 words, about 2 min04Use of Force and Defensive Tactics
This domain tests whether you can apply the objective-reasonableness standard from Graham v. Connor, apply Tennessee v.
425 words, about 2 min05Investigations and Evidence Handling
This domain tests whether your investigations can survive suppression and whether your evidence handling can survive a chain-of-custody challenge years later. The chain is every transfer of an item from recovery to court: who collected it, when, where, how it was packaged and sealed, and every subsequent handoff.
469 words, about 2 min06Traffic Enforcement and Motor Vehicle Law
This domain tests DC Code Title 50 and DCMR Title 18 (Traffic and Parking), the impaired-driving statutes, and whether your traffic stop produces a case that survives a motion to suppress. United States: a stop is valid if the officer has reasonable suspicion or probable cause of a traffic violation, regardless of the officer's subjective motive.
440 words, about 2 min07Report Writing and Documentation
This domain tests whether your report states every element of the offense in observable facts, in a form the prosecutor can paper and the defense cannot easily attack. The narrative is chronological, first person, active voice.
443 words, about 2 min08Ethics, Professionalism, and Agency Policy
This domain tests whether you know the rules that end careers - truthfulness, reporting misconduct, conflicts of interest, and off-duty conduct - and whether you can apply them under pressure from a partner or a supervisor. Truthfulness: a sustained finding of untruthfulness during an investigation destroys the officer's credibility for Giglio and Brady purposes and typically results in termination.
