EADF Cheat Sheet 2026: One-Page Review of Must-Know Facts

Quick Facts Snapshot

Before diving into domain content, anchor yourself in the exam's hard facts. This is the ArcGIS Developer Foundation 2201 (EADF) exam, administered by Environmental Systems Research Institute, Inc. (Esri) - and this cheat sheet only reflects that specific exam code, not any later blueprint carrying a similar name. If you want the full narrative behind these numbers, the EADF Study Guide 2026 walks through how to sequence your prep around them.

Domain Weight Breakdown

EADF 2201's blueprint is built from four domains. Esri publishes these weights as-is, and they sum to 99% - not 100% - so don't second-guess the source. Study time should roughly mirror these percentages, with the heaviest emphasis on the two largest domains.

If you haven't yet mapped every subtopic inside these four areas, the EADF Exam Domains 2026 guide breaks each one down further than this cheat sheet has room for.

Functionality & Visualization Essentials

Esri's own guidance is explicit that this domain rewards understanding of API and service selection and visualization behavior over language-specific syntax. Practice questions that describe a scenario and ask "which approach accomplishes this" mirror the real test far better than syntax-recall flashcards.

Solutions Design Essentials

Questions here typically present a business or technical scenario and ask which architecture fits - this is judgment testing, not trivia. Candidates who have spent real time configuring ArcGIS deployments, not just reading about them, tend to recognize these patterns faster.

Content Management Essentials

Authentication & Security Essentials

This is a good moment to note what EADF 2201 deliberately does not test heavily: it stays away from deep programming-language syntax questions and from hands-on security-pattern implementation. It tests whether you understand the "why" and "which" behind API selection, authentication, hosting, Arcade, visualization, and data queries - not whether you can write a full authentication module from scratch.

Question Format & Timing

Per the April 2026 Exam Information Guide, EADF 2201 consists of 65 English-language multiple-choice questions delivered in a 1-hour-45-minute window. That works out to a little over 90 seconds per question on average - comfortable if you're not stuck rereading scenario text repeatedly.

• All questions are multiple choice - no drag-and-drop, no live coding sandbox.
• The exam is offered in English.
• Scenario-based phrasing dominates, especially in Solutions Design and Functionality & Visualization.

If you're unsure exactly how many correct answers you need out of 65, review EADF Passing Score 2026 before exam day so there are no surprises about the scoring threshold.

Fee, Delivery & Registration Mechanics

Esri's foundation-tier voucher for EADF 2201 was priced at USD 275, effective January 2026, before the exam's retirement. You can sit for it through either a Pearson VUE test center or via OnVUE online proctoring - both were offered up until retirement.

• Voucher price: USD 275 (foundation tier, effective January 2026)
• Delivery options: Pearson VUE test center or OnVUE remote proctoring
• Retirement date: June 30, 2026 - after this, EADF 2201 specifically is no longer scheduled, though its blueprint remains distinct from ArcGIS Developer Foundation 2026
• Prerequisites: None mandatory - Esri recommends preparation resources but does not require a specific course

Who Actually Sits for EADF

Esri's recommended candidate profile is someone with at least two years of hands-on experience working with the ArcGIS system and its APIs. This isn't an entry-level "read a textbook and pass" exam - the scenario-based questions in Solutions Design and Functionality & Visualization assume you've actually configured layers, queried services, and made hosting decisions before, not just read about them.

Preparation resources are recommended, not mandatory, which means there's no gatekeeping training course standing between you and the exam. That flexibility is also why practicing against realistic scenario questions matters so much - you're largely self-directed. Working through timed practice questions on our EADF practice test platform is one of the fastest ways to close the gap between "I know ArcGIS" and "I can answer a 90-second scenario question about it correctly."

One-Page Final Review Checklist

Use this as your literal last-24-hours skim. Every line maps to a domain weight above - nothing generic, nothing borrowed from unrelated exams.

If any of these bullets feel unfamiliar rather than "oh right, I remember this," that's your signal to go back to the source material for that specific domain instead of rereading everything. A quick way to test recall honestly is a timed pass through practice questions on our practice test site right before you commit to a final exam date.
