CERTIFIED INTERIOR DECORATORS INTERNATIONAL Founded in 1997 by distinguished interior designer Ron Renner, Certified Interior Decorators International (C.I.D.) is dedicated to providing the educational training and testing required for talented individuals seeking recognition as a "Certified" professional in the interior decorating industry.

In the early 90's, Mr. Renner conceived the original idea of "Certifying" interior decorators for the purpose of clarifying the difference between designers and decorators and the educational requirements for both. C.I.D. is a professional membership association and the ONLY body for accrediting and certifying interior decorators.

C.I.D. has partnered with educators to provide C.I.D. approved programs by direct mail or through online courses, allowing potential members to qualify to apply for professional credentials as a "Certified Interior Decorator". Over the past 20 years, C.I.D. has become the consumers choice for attaining recognized status as a decorating professional.

Certified Interior Decorators International (C.I.D.) serves as a dual purpose certifying body and professional membership association.

As NCIDQ and the professional associations IIDA, ASID, ICD and IDEC have been working to raise the bar for the interior design profession, other associations have been focusing on establishing credentials for the decoration industry. Any industry that decides to create guidelines and raise the professionalism of its industry deserves commendation and the decoration community deserves no less.

I appreciate the information you sent and feel that it is important for all our showrooms to be aware of your association and the principles Certified Interior Decorators International stands for. Many of our showrooms are frustrated with clients who claim to be decorators and come in expecting the showroom personnel to do their job. Showrooms would be much more willing to work with a decorator who identifies themselves as a Certified Interior Decorator (C.I.D.).
