Appian ACD301 case studies
Appian ACD301 · Put your knowledge to work in context.
The Appian Certified Developer credential (commonly referenced by the code ACD301) is a professional certification for developers who build applications on the Appian low-code platform. It is aimed at practitioners who already work hands-on with Appian design objects - data types and records, process models, interfaces, and application security and deployment settings - and who want an independent, structured way to validate and sharpen that knowledge. This study page is an independent preparation resource and is not affiliated with, endorsed by, or sponsored by Appian. The practice material is organized around four equally weighted domains: data modeling and data management (25%), process modeling and automation (25%), interfaces and user experience (25%), and application configuration, security, and deployment (25%). The Appian ACD301 case studies are 5 cases and about 3,108 words.
