Preparing for the the LASD dispatcher pipeline

Agency: LASD Region: Southern California Primary Exam: CritiCall

Los Angeles County Sheriff's Department hires Sheriff's Security Officers and Custody Assistants alongside its dispatch ranks, and the LASD dispatcher test pipeline runs through County of Los Angeles civil service. LASD applicants commonly encounter CritiCall as the primary screening exam, with additional typing and data-entry validation. The Los Angeles County Sheriff dispatcher hiring process moves in cohorts, so a missed cut means waiting for the next opening.

What LASD tests on the dispatcher exam

What LASD tests on the dispatcher exam usually mirrors the national CritiCall modules — call summarization, memory recall, map reading, prioritization, and the dual-task checking exercises. The 82% nationwide first-attempt CritiCall fail rate is not a typo. LASD applicants who treat this like a memorization exercise tend to wash out in the audio sections.

Why audio matters
The CritiCall sections that most often decide outcomes — Pattern A recall, Pattern B call-taking, and the Pattern C dual-task checking modules — all hinge on listening under pressure. Reading-based prep does not transfer.

How DispatchPrep prepares LASD applicants

DispatchPrep approaches the LASD dispatcher exam audio-first. Every Pattern A, B, and C clip is studio-produced so you train the same way you will test. Our coverage maps directly to the modern POST battery test names used in California: Test 7 — Recalling Information (Pattern A audio, no notes), Test 8 — Call-Taking (Pattern B, multi-clip with notes), Test 9 — Following Oral Directions (Pattern A with notes), Test 10 — Checking Coded Information (Pattern C1), and Test 11 — Checking and Listening (Pattern C2, dual-task). You train under real-time exercise conditions, on the same audio style and pacing the real exam delivers.
