Free, offline-first resources for working dispatchers and the supervisors who train them. No accounts, no tracking, no friction.
Built by an operations supervisor at a consolidated 911 center — 23 years in emergency communications, 150+ telecommunicators, 40+ agencies. Not a vendor. Not selling a platform.
Real-world incidents broken into structured dispatch challenges. 46 exercises — the complete archive.
Xebra Delta continues to develop EAP and EOP exercise packages for PSAPs — turning the documents that sit unread in a binder into ready-to-run dispatch training built from your actual plans and geography.

Study tools and references for 911 professionals at every stage.
450 practice questions across all 7 NENA ENP exam domains with spaced repetition, a review queue, progress tracking, and a full 100-question timed exam simulation. Installable to your home screen for offline use.
Standardized typing test built for PSAP and ECC hiring. Dispatch-relevant passages, configurable duration and pass/fail thresholds, adjusted accuracy tracking that counts corrected mistakes, printable results for applicant files, and full applicant history with CSV and JSON export. Single HTML file — host it anywhere, no internet required.
AI-powered dispatch intelligence. Analyzes caller tone, streamlines incident decisions, and confidently gets just enough wrong to be operationally concerning. Raccoon probability engine included at no additional cost.
Structured post-incident review templates built around ICS-100 and NIMS standards. Guides supervisors through call documentation, team debrief facilitation, and identifying systemic patterns.
Every exercise is free to use in shift briefings, training blocks, or self-study. Print to PDF for handouts. No login, no procurement, no subscription. Have a question or an incident you think should be an exercise? Drop a note.

New dispatch training work now lives elsewhere. The EAP and infrastructure exercise work continues through Xebra Delta. See the field note for context.
These tools come from a 911 ECC operations supervisor with emergency management credentials — not a training vendor trying to sell a platform.
Everything here is free, runs offline, and carries no tracking or advertising. If a tool helps your center, that's the point.
Every exercise is a single HTML file. Nothing is sent to any server. Notes save locally to your own browser. You control your data entirely.
