Skills You Should Be Ready to Demonstrate

• Interpreting implementation guides
• Managing FHIR API behaviors
• Structuring resource models
• Executing implementation tasks
• Validating FHIR data

How to Prepare

Review the official FHIR specification documentation, focusing on resource definitions, datatypes, and metadata. Practice identifying resource relationships and canonical URLs. Utilize the HL7 International exam guide to understand the structure of the 125 questions. Engage with the FHIR community through official support channels to clarify implementation challenges and ensure your knowledge aligns with current standards and technical requirements.

Domain Study Guidance

Understanding Implementation Guides: Study Guidance

This domain evaluates your ability to interpret and apply implementation guides within healthcare environments. Candidates learn to navigate canonical URLs, enforce conformance rules, and adapt FHIR profiles to fulfill custom clinical or administrative data exchange requirements.

• Interpreting conformance rules
• Applying implementation guide constraints

FHIR API Behavior: Study Guidance

This domain examines RESTful interaction patterns, search mechanisms, and transactional operations across FHIR servers. Candidates must understand how HTTP verbs, parameters, response codes, and resource identities govern communication between healthcare applications and services.

• Managing resource identity
• Handling API interactions

Resource Model and Structure: Study Guidance

This domain focuses on fundamental FHIR building blocks, including resource modeling, primitive and complex datatypes, and metadata elements. Candidates demonstrate understanding of resource composition, narrative generation, extensions, and logical relationships between clinical models.

• Defining resource elements
• Utilizing resource metadata

Implementation: Study Guidance

This domain addresses the practical application of FHIR resources within operational healthcare environments. Candidates must understand business identifiers, reference types, bundle construction, and strategies for mapping legacy clinical data structures into standardized FHIR representations.

• Implementing resource references
• Managing business identifiers

Troubleshooting and Validation: Study Guidance

This domain covers techniques for diagnosing communication errors, validating resource content against profiles, and ensuring specification compliance. Candidates learn to interpret OperationOutcome resources and resolve data formatting or structural issues effectively.

• Validating resource content
• Troubleshooting implementation errors

Exam-Day Guidance

You have 210 minutes to complete 125 questions. Manage your time carefully across the 5 domains. Read each question to identify the specific resource or API behavior being tested before selecting your answer.
