Every exam.

DispatchPrep covers the complete California POST Dispatcher Selection Test Battery and the highest-frequency CritiCall modules — the two gatekeepers to a dispatcher career.

POST Audio Modules — T7 to T11
POST — Test 7

Recalling Information

Listen to a single radio dispatch. No notes, no replay. Answer from memory after the audio ends — the baseline auditory working-memory module.

POST Battery
POST — Test 8

Call-Taking

Multiple sequential calls with notes allowed throughout. Summarize each incident under realistic time pressure.

POST Battery
POST — Test 9

Following Oral Directions

Single audio clip with notes allowed during playback. Answer questions from your notes — the audio-critical module where production quality matters most.

POST Battery
POST — Test 10

Checking Coded Information

Match entries on a code sheet in real time as dispatch reads them aloud. Tests sustained attention and selective matching.

POST — Test 11

Checking & Listening

Dual-task. Track a live radio log while checking a hot sheet — simultaneous audio and written tasks across multiple information streams. The battery's most complex module.

Why DispatchPrep

The exam is audio.
So is the prep.

Most test prep gives you PDFs. The dispatcher exam asks you to listen and respond in real time. We built DispatchPrep around that reality.

Professional studio-grade audio

Every exercise uses ElevenLabs Studio-tier voice production — indistinguishable from live human dispatch recordings. No robotic TTS, no cheap synthetic voices.

Real-time exercise conditions

Timed exercises mirror actual exam pacing. The player fires cues exactly once — no scrubbing, no replays — because that's what test day feels like.

Dual-task and live hot sheet modules

Test 11-style cross-reference exercises and CritiCall's radio log tasks require candidates to hold and act on multiple information streams simultaneously. We built them.

California-specific content

Built directly from the California POST Examinee Guide, not generic cop-show scenarios. Scenarios reflect the language and context of actual California dispatch work.

Why this works

Grounded in
the research.

Most dispatcher prep treats the exam as reading comprehension. It isn't. Tests 7, 9, 10, and 11 — and the core CritiCall modules — are auditory working-memory tasks under cognitive load. Preparation that doesn't match the stimulus doesn't build the skill.

82%

first-attempt fail rate on CritiCall. The cognitive demands of the exam are genuinely at or above the limit of most unprepared candidates — documented in the NASA-TLX workload studies on dispatcher cognition.

Cognitive load, measured.
Research basis for the product
Audio WM

Auditory working memory is a domain-specific skill. Practicing with text does not build the auditory faculty the test measures. Only practice with audio under realistic conditions — single-listen, no notes, panicked caller — builds the specific capacity being tested.

Domain-specific working memory
The core product rationale
Banse & Scherer

Our ElevenLabs voice configurations are calibrated using the Banse & Scherer (1996) acoustic-emotion framework — mapping physiological vocal cues to arousal states appropriate for emergency-call simulation. Our differentiation is auditable, not asserted.

FAQ

Common
questions.

DispatchPrep covers all 11 modules of the California POST exam preparation — six foundational text modules (Tests 1–6: Public Safety Bulletin, Assigning Field Units, Evaluating Facts, Setting Priorities, Reading Comprehension, Sentence Clarity) and five audio-critical modules (Tests 7–11: Recalling Information, Call-Taking, Following Oral Directions, Checking Coded Information, Checking & Listening). For CritiCall we cover the five highest-frequency modules at launch: Typing, Data Entry, Call Summarization, Decision Making, and Memory Recall. Additional CritiCall modules are added on an ongoing basis.
Tests 7, 9, 10, and 11 of the POST battery — and several CritiCall modules — require you to listen to recordings and respond accurately. If your prep uses poor-quality or synthetic audio, you're training in conditions that don't match the exam. DispatchPrep uses ElevenLabs Studio-tier production, meaning the voices are clear, natural, and realistic enough that you're actually building the listening skills the exam will test.
We don't offer a free trial, but we do offer a 30-day money-back guarantee. If DispatchPrep doesn't meet your expectations, contact us and we'll refund your purchase — no interrogation required. You can also try one practice question above with no account required.
Lifetime access. You purchase once and can return to the platform as many times as you need — whether that's in the weeks before your exam or months later if you reschedule.
No. DispatchPrep is an independent test preparation service produced by Necessary Productions. Content is built from publicly available California POST exam documentation and materials, including the official Examinee Guide. We are not endorsed by or affiliated with California POST or any government agency.
CritiCall exams vary somewhat by agency in terms of which modules are administered and weighting. At launch we cover the five most frequently used modules — Typing, Data Entry, Call Summarization, Decision Making, and Memory Recall — and we add additional modules on an ongoing basis. We recommend also checking the specific agency's job posting for module details.

Your career

Dispatcher positions are competitive, and preparation matters. Give yourself the edge with the only platform that takes the audio seriously.
