Interior decorators may be self-employed, or freelance, and charge an hourly rate for services or negotiate a contract amount for a specific job. Other interior decorators choose to work for a company, such as a design firm, furniture store or other material manufacturer. Regardless of where you work, you will have a business card. Adding a certification to your business card boasts your credentials and dedication to professionalism.

National Council for Interior Design Qualification

The National Council for Interior Design Qualification (NCIDQ) is one place to start. NCIDQ Certified interior designers have distinguished themselves by demonstrating a specific set of core interior design competencies, supported by verified work experience and a college degree. They have proven their knowledge of current standards established to protect public health, safety and welfare, as well as mastery of aesthetic considerations. They have earned the industry’s highest standard of proficiency in interior design principles by successfully passing their examination.

The Council for Interior Design Qualification (CIDQ) administers the NCIDQ Exam. Interior designers must complete a minimum of six years of specialized education, work experience, and pass the three-part NCIDQ Exam. The specialized education includes a Bachelor’s or Master’s degree from a CIDA (Council for Interior Design Accreditation)-accredited program. Work experience requires 3,520 hours of qualified interior design experience. You can find other criteria at CIDQ.  

Certified Aging-in-Place Specialist

The Certified Aging-in-Place Specialist (CAPS) designation program teaches technical, business management, and customer service skills. These are essential to competing in the fastest growing segment of the residential remodeling industry: home modifications for the aging-in-place. The certification provides the skills to help your clients make the right choices, and it gives you more security in the remodeling market niche that is continuing to grow in popularity. The National Association of Home Builders offers the program that consists of three required courses:

  • Marketing and Communicating with the Aging in Place Client (CAPS I)
  • Design Concepts for Livable Homes and Aging in Place (CAPS II)
