Since August, more than 320 interior designers have registered with the Indiana Interior Design Coalition. Legislation passed last year stipulates that interior designers can't use the title "registered interior designer" unless they meet the requirements and register.

Designers qualify if they have 15 years of experience and no training, or 10 years of experience and two years of interior design training, and pay the $100 fee.

Beginning in January 2012, registered interior designers in Indiana will have to pass either the National Council for Interior Design Qualification or the Architect Registration Exam.

The NCIDQ is the industry standard, and the council lists 47 designers in Indiana with up-to-date NCIDQ certification.

Indiana designers who register before January 2012 can keep their registration without testing if they meet the continuing education requirement of 12 hours every two years.
