The Decorator Training Institute (DTI) program is the ONLY course of study licensed by Certified Interior Decorators International (C.I.D.) to teach "Interior Decorator Certification".

The Decorator Training Institute Online Course and Home Study programs were written specifically for the Interior Decorator by Ron Renner, founder and president of Certified Interior Decorators International (C.I.D.). Instruction includes the basics of certification, elements of interior design and decoration, business practice and "How to Charge for Services". Teaching also includes the latest information concerning the practice of interior design versus the role of the "Certified Interior Decorator".

In the early 90s, Mr. Renner conceived and implemented the idea of "Certifying" Interior Decorators. In 1997, Ron founded Certified Interior Decorators International (C.I.D.), which was established as the only membership association exclusively for Certified Interior Decorators. Certified Interior Decorators International (C.I.D.) also serves as the only "certifying body" for interior decorators in the interior decorating industry.

The Decorator Training Institute (DTI) program is the most informative and direct route to C.I.D. Certification. Upon completion graduates are then qualified to join Certified Interior Decorators International (C.I.D.).

Help Me Choose: Online Course or Home Study?

Both programs are editions of the same Decorator Training Institute (DTI) Program, written by Ron Renner, Founder and President of Certified Interior Decorators International. Graduates of both courses of study receive the same certificate of graduation from DTI. Your choice between the two programs will be partly one of personal preference, based on whether you prefer to work from a book or in front of a computer screen.

The Workbook Course
includes hands-on projects, furniture templates and an interior design color wheel in addition to leaving you with the printed workbook for future reference. All other things being equal, it is the option we recommend most highly. This version of the course provides more room for personal interaction with the instructor, who will personally critique your work on the hands-on projects, making the connection between book learning and practical experience. $1295.00

The Online Course
is for those who prefer online studies. You can start your studies immediately, using the password you will receive shortly after your credit card payment clears. The online course can be a completely paperless option. Students tend to complete the online course a little more quickly and grading of the final exam is immediate because it is automated through the website. The Online Course is IPad compatible. $795.00

Member Testimony
"After years of having a passion for home furnishings and a strong interest in interior design, I was fortunate to be offered a job working in retail furniture sales. I feel the knowledge and experience I gained working with customers and attending trade shows was as valuable as years in a classroom, but it did not give me the credibility a formal education would have provided. Ron Renner's Decorator Training Institute certification program enabled me the opportunity to become a professional Interior Decorator in a very affordable and timely manner. This is a wonderful program for someone who has a 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."
