In 2023, the American Health Information Management Association®(AHIMA) began a job task analysis for the Certified Health Data Analyst (CHDA®) professional certification. The purpose of the current job analysis study was to validate the current tasks that are in the content outline for the CHDA program as well as identify additional tasks that may be required for CHDAs in their current role. The result of the CHDA job task analysis study resulted in an updated Content Outline to ensure the most current state of practice is being tested in the examination. You can look at the 2024 CHDA Content Outline as well as a “2024 Crosswalk” that shows and highlights the changes between the previous Content Outline and the new one.
