What spelling measures
Spelling of everyday and public-safety vocabulary — street types, medical terms, common surnames.
These assessments are modular — an agency chooses which components to run and sets its own minimum for each one. We can tell you what the skill is and how to get better at it. We can't tell you what score your agency wants, and anyone who quotes you a universal one is guessing.
How our drill works
It's timed. You get a countdown clock and a fixed run length, because working accurately with a clock visible is a different skill from working accurately without one, and only one of them is being assessed.
Each run samples a fresh set of questions from our bank, so repeated attempts give you a different selection rather than the same items in the same order. Every question carries a written explanation — the reasoning is the part that transfers to the next question.
When the run ends you get a breakdown, not just a percentage. The point is to show you where the points went, so the next run can be different.
Which assessments include spelling
Agencies use different vendors, and each picks its own combination of components. This module appears in the batteries below — but check the job posting, because an agency using one of them may not run every part of it.
CritiCall
Biddle Consulting Group, Inc.
The most widely used pre-employment assessment for 911 dispatchers and public-safety telecommunicators in the United States. It is modular: an agency picks which components to run, so no two agencies test exactly the same set.
Emergency Communications (ECOMM) Exam
Ergometrics & Applied Personnel Research, Inc.
An Ergometrics-authored assessment distributed through the National Testing Network. Candidates typically pay to sit it and can share their score with multiple participating agencies. It is a different product from the National Dispatcher Selection Test (NDST), which is published by Stanard & Associates — the two are frequently confused.
POST Entry-Level Dispatcher Selection Test Battery
California Commission on Peace Officer Standards and Training
Used by California agencies. It is delivered on paper, with a pencil — not on a computer — and scores are reported as a T-score. Agencies set their own minimum.
How to get better at spelling
Specific to this module, and specific enough to change what you do on your next run.
Learn the public-safety vocabulary specifically
Street types, common medical terms, and frequently encountered surnames come up far more than general vocabulary does. That is a small, finite list and it is worth working through it directly rather than practicing spelling in general.
Read every option before choosing
The wrong options are built to look right at a glance. Recognizing the shape of a word is not the same as reading it, and shape-recognition is exactly what these items are designed to defeat.
Work the patterns, not the word list
Doubled consonants before a suffix, -ance versus -ence, -ible versus -able. Learning the handful of rules generalizes to words you have not seen; memorizing individual words does not.
Say it out in syllables when you are stuck
Breaking an unfamiliar word into syllables surfaces the dropped or doubled letter more reliably than staring at the whole word does.
Track which words you actually miss
After a run, note the specific words you got wrong rather than just the score. Most people's misses cluster into a small, personal set that they will keep missing until they look at it deliberately.

Common questions
Is the spelling American or British?
American English throughout, which matches the assessments used by United States agencies.
What kind of words come up?
Everyday vocabulary plus the terms a telecommunicator actually types — street types, common medical and injury terms, and frequently encountered surnames.
Is spelling really part of a dispatcher assessment?
It appears as a component in several of the assessment batteries used for these roles, though not every agency runs every component. Check the job posting for the assessment you are sitting.
How many questions are in the bank?
Each run samples a fresh set from the bank, so repeated attempts give you a different selection rather than the same items in the same order.
