The Decorator Training Institute (DTI) certification program, written by Ron Renner, President and Founder of Certified Interior Decorators International, functioned as an educational division of Certified Interior Decorators International (C.I.D.) for seventeen years. Mr. Renner and the Board of Directors of Certified Interior Decorators International have agreed to merge the DTI training program with Certified Interior Decorators International, rebranding the course of study as the "C.I.D. Certification Program".
"The C.I.D. 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".

accolades are not enough to express the value of your wonderful
program. When I was only half way through the course I had
an opportunity to bid on a large project and I believe, due
to the information in the course, I was able to win a large
decorating project here in California. Now all the avenues
have opened up for me and I am very busy decorating."

practical application that will prove to be invaluable for
my entry into the Interior Decorating profession."
