NYPD Lieutenant common mistakes

NYPD Lieutenant · Understand the traps and how to avoid them.

Mistake 1

Treating a supervisor's order as controlling whenever it conflicts with the Patrol Guide, instead of recognizing that the written procedure governs and the conflict must be escalated.

Candidates study procedures in isolation and never rehearse the scenario where a sergeant, lieutenant, or commanding officer gives a verbal direction that contradicts a written rule; under time pressure they pick the answer that sounds most deferential.

What to do instead

Drill a fixed decision sequence for every order-conflict question: identify the written rule, identify the verbal order, state who has authority to modify the procedure, then choose the answer that follows the written rule and routes the disagreement up the chain. Practice writing that sequence out in one sentence before reading the answer choices.

Mistake 2

Answering use-of-force and stop-and-frisk questions by picking the most restrictive option (or the most permissive one) rather than matching the level of force or the scope of the stop to the specific facts stated.

Candidates memorize slogans like 'minimum necessary force' without learning the graded factors (severity of the crime, immediate threat, active resistance versus passive, flight) that make one option correct and another wrong on a given fact pattern.

What to do instead

Build a one-page matrix of force levels against resistance categories and a separate matrix of stop, frisk, and search authority against articulable facts. For every practice question, underline the fact that triggers the escalation or de-escalation before looking at the choices.

Mistake 3

Applying search-incident-to-arrest or inventory rules without checking the arrest's validity, the timing relative to the arrest, and the area within the arrestee's immediate control.

Candidates learn the exceptions to the warrant requirement as a list and then apply the label without running the elements; they miss that a search incident to a lawful arrest fails if the arrest itself was unlawful or if the search occurred after the arrestee was secured and removed.

What to do instead

For each exception, memorize a three-item checklist (predicate, scope, timing) and verbally run it on every scenario. Practice distinguishing lawful arrest plus contemporaneous search from search after transport, and inventory search from investigatory search.

Mistake 4

Choosing the harshest disciplinary outcome in a discipline scenario, ignoring progressive discipline, the disciplinary matrix, and the role of the commanding officer's recommendation versus the Department Advocate's authority.

Candidates equate 'supervisor' with 'punisher' and assume the exam rewards severity; they also conflate the roles of the commanding officer, the Department Advocate, and the trial commissioner in the disciplinary process.

What to do instead

Map the disciplinary workflow end to end: who investigates, who recommends, who adjudicates, what the matrix prescribes for a first versus repeat offense, and where a supervisor's discretion actually sits. Answer discipline questions by locating the scenario at the correct step in that workflow.

Mistake 5

Missing the distinction between what a lieutenant may handle informally at the command level and what must be referred to Internal Affairs, the Department Advocate, or another unit.

Candidates study the bureaus and units as an org chart without learning the referral triggers, so they default to 'handle it within the command' on allegations that mandate outside notification.

What to do instead

Create a referral-trigger list keyed to allegation type: corruption, excessive force, domestic violence, bias, drug involvement, and so on. For each, note the mandatory notification and the time frame. Rehearse with short scenarios where the only difference is the allegation type.

Mistake 6

Skimming a long report or memo and answering from the first paragraph or from general impression rather than locating the specific line that resolves the question.

Reading comprehension items on this exam embed the answer in a dense administrative document with distractor details; candidates under time pressure read for gist and then select an answer that is plausible but contradicted later in the text.

What to do instead

Practice a two-pass method: first pass reads the question stem to know what to look for, second pass scans for the named person, date, or number. Train yourself to point to the exact sentence supporting your answer before selecting it.

Mistake 7

Writing report-review answers that fix grammar and spelling but leave structural defects: missing elements of the offense, unsupported conclusions, inconsistent times, and absent follow-up assignments.

Candidates treat report review as proofreading because that is the most visible layer, and they have not internalized the required elements of common offense reports or the standard report fields.

What to do instead

Use a fixed review checklist on every practice report: elements of the offense, who/what/when/where, chain of custody or evidence noted, witnesses identified, follow-up assigned, and internal consistency of names, times, and locations. Grade yourself against the checklist, not against how polished the prose looks.

Mistake 8

Answering personnel-management scenarios by choosing the option that avoids confrontation, such as transferring the problem or documenting later, instead of addressing performance or conduct directly and contemporaneously.

Candidates confuse good leadership with conflict avoidance and have not practiced the supervisory conversation steps: identify the deficiency, state the standard, document, set a follow-up date, and escalate only if the behavior persists.

What to do instead

Memorize a five-step supervisory intervention model and apply it to every personnel scenario. Eliminate answer choices that delay the conversation, delegate the confrontation downward, or skip documentation.

Mistake 9

Confusing community-relations gestures with substantive problem-oriented policing, choosing 'hold a meeting' or 'increase patrols' when the scenario calls for diagnosing an underlying condition with partners.

Candidates default to visible, familiar responses and have not practiced distinguishing a one-time event from a recurring condition that requires analysis, partner agencies, and measurable follow-up.

What to do instead

Learn the scan-analyze-respond-assess cycle and apply it explicitly: for each scenario, name the underlying condition, the partner who controls it, the measurable objective, and how success will be assessed. Reject answers that are purely symbolic or purely enforcement-only when the facts describe a persistent condition.

Mistake 10

Managing the clock badly: spending too long on scenario questions early, then rushing the reading-comprehension and report-review sections where careless errors cost the most points.

Candidates practice content but never practice under timed conditions, so they do not know their own pace or which sections reward speed versus deliberation.

What to do instead

Take at least three full-length timed practice runs and record time per section. Set a per-question budget, learn to flag and return on scenario items, and reserve a fixed block at the end for the reading and report-review items where a second look pays off most.
