An Adobe Certified Expert (ACE) is a person who has demonstrated proficiency with Adobe Systems software products by passing one or more product-specific proficiency exams set by Adobe.
Adobe sets out three levels of proficiency at this level:
- Single product certification (i.e. Photoshop CS5)
- Specialist certification in a specific medium (print, web or video)
- Master certification recognizes certification for an entire product suite
Recommended preparation for ACE exams is the "Classroom in a Book" series of self-paced training workbooks.
