How to Become an Interior Designer in 4 Simple Steps

If you have a passion for art, design, and architecture, then a career as an interior designer may be a good fit.

Interior designers are more than just decorators; they are an integral part of the designing, planning, and construction of new homes and other spaces.

If you are going to be an interior designer, you will need a formal education.

You will also need to deal with certification and any required licenses.

This article will give an in-depth view of what education you need to become an interior designer, what licenses you need, and what kind of certifications you require.

Steps to Becoming an Interior Designer

Here is a quick step-by-step guide on how to become an interior designer.

Step 1: Get a Degree

The first thing to do is to get an education in interior design. Most employment opportunities require candidates to have a bachelor’s degree but educational programs exist at the associate’s bachelor’s, and master’s level.

Step 2: Receive Certification (Optional)

The next step after graduating from your program is to get certified. Certification is not required by any means, but it will make you a more competitive applicant for positions. Those who hold interior design certification are the only ones who can use the title “certified interior designer” or “registered interior designer.”

Step 3: Maintain Certification

If you opt to receive certification you will have to renew every year. Renewal involves sending in proof of completed continuing education credits and any applicable renewal fees.

Interior Designer Education Requirements

Interior design is about more than just being good with decorations.

Interior designers study a broad range of subjects from building codes and architecture to psychology and human behavior. Interior designers must not only know about the mechanics and principles of design but also how space, color, and lighting work to solicit certain emotional reactions from humans. Interior designers are part artist, part manager, and part psychologist, so their education must reflect this broad skill set.

The requirements for being an interior designer are usually a bachelor’s degree, but you can get an associate’s, bachelor’s, or master’s level education in interior design.

Other skills related to construction and design may be helpful, such as blueprint reading or contracting.

Currently, no state has licensure requirements for interior designers, except for Louisiana, Florida, Nevada, and Washington D.C., where you must be registered with the state if you are going to work in any commercial space.

Although you do not need a license to work, most states give interior designers the option to receive voluntary National Council for Interior Design Qualification (NCIDQ) registration or certification. Those that receive NCIDQ certification are the only individuals who can work under the title “certified interior designer” or “registered interior designer.”

The two main accrediting agencies in the US for interior design programs are the Council for Interior Design Accreditation (CIDA) and the National Association of Schools of Art and Design (NASAD).

These two organizations offer accreditation to associate’s, bachelor’s, and master’s level programs. Programs accredited by CIDA are the most likely to prepare one for a career in interior design as CIDA accredits professionally-oriented interior design programs while NASAD provides more general accreditation for art and design schools. Individual programs can also be accredited directly by the US Dept. of Education.

In order to sit for the NCIDQ certification exam, students must graduate from an accepted accredited program. The Council for Higher Education Accreditation has a list of accepted programs and accrediting agencies.

Training Information & Types of Interior Designer Degrees

Education programs for interior design exist at the associate’s, bachelor’s, and master’s degree levels. At the associate’s level, one can pursue an associate of arts (AA) in interior design.
