The IDEX Prep Online class was inspired by many interior designers who needed,  and requested an online class. In order to satisfy this industry wide need, Deni Mosser, CID developed the concept, framework, lessons, quizzes, handout materials and the custom online delivery system.

Completion of this class will help you pass the IDEX® California exam in order to become a Certified Interior Designer in the state of California (under California Business & Professions Code Section 5800).

(Passing the IDEX® California exam alone will not make you a CID. You must also satisfy all of CCIDC’s education and experience criteria.)

Also, our classes are accepted by CCIDC for 1.0 units of CEU credit. That’s a full 10 hours, enough to cover two years of CEU’s for designers who are already “Certified” with CCIDC.
