All states require that you work under a supervising architect. During this time you’ll get valuable work experience that will help you advance your career and earn credit in the AXP. AIA offers resources to help you complete AXP.
You’ll also need to pass the ARE. It’s a multi-part exam that will test your knowledge and skills in a variety of segments within the practice of architecture. AIA offers resources to help you pass the ARE.
Once you pass the exams and complete the experience requirement, you can register for a license. Individual states grant licenses. You can become licensed in multiple states.
Compare licensure requirements of the 54 jurisdictions to decide where to get your initial license. Typically, to maintain or renew your license, you’ll need to earn continuing education credits each year.
