C.I.D. serves as a dual purpose certifying body and professional membership organization. No other organization, program, or school can "certify" decorators.

Founder, President, and nationally recognized Interior Designer, Ron Renner, ASID, conceived the idea of certifying Interior Decorators for the purpose of clarifying the difference between Interior Designers and Interior Decorators and the educational requirements for both. The term "Certified Interior Decorator" and the appellation "C.I.D." are registered trademarks filed in 1997 in the U.S. Patent and Trademark office in Washington, D.C. The use of CID or C.I.D. is exclusively for Certified Interior Decorators and is well established in the Interior Design and Decoration industry.

Certification Program

Our goal is to certify individuals by offering a direct certification program that teaches those who have a natural talent for Interior Decoration. Our exclusive C.I.D. Certification Program is taught in an easy, informative and concise manner through the use of online education materials or our direct workbook correspondence program. Both programs directly result in certification AND a full one-year annual membership (a $295 value). The C.I.D. program is the ONLY program you will need and is the most direct route to certification. No other schooling is required.

"Any industry that decides to create guidelines and raise the professionalism of its industry deserves commendation and the decoration community deserves no less."
Charlotte Jensen
FASID Past President of the National Council of Interior Design Qualification (NCIDQ)
"Showrooms would be much more willing to work with a Certified Interior Decorator (C.I.D.)"
Dallas Decorative Center

"This is a wonderful program for someone who has talent for decorating but wants or needs to add the validity that becoming certified offers. The C.I.D. designation and membership in the Certified Interior Decorators International organization will open doors and lets consumers know you are a professional they can trust. So... thank you Mr. Renner."
