Becoming an interior designer requires schooling and, in many states, an interior design license. If you’ve thought of pursuing this path, there are many steps to getting your career off the ground.

In this article, we’ll explore the basic steps of becoming an interior designer and state qualifications.

How to Become an Interior Designer: Step by Step

How to Become an Interior Designer

While you can become an interior decorator without schooling or licensure, the steps to becoming an interior designer are much more intricate. Interior designers are responsible for the function of a space and, in addition to learning design concepts, must also be familiar with zoning requirements and computer-aided design programs.

Step 1: Earn an Associate’s or Bachelor’s Degree

The first step to becoming an interior designer is enrolling in an interior design program and earning an associate’s or bachelor’s degree. During schooling, you’ll need to take classes on fundamentals of design, computer-aided design software, and drawing. If you earn a bachelor’s degree, you’ll also take courses in marketing and business, which can set you up to work for yourself.

While not all states require a bachelor’s degree to work as an interior designer, many do. Plus, a bachelor’s degree is the better route if you want to work for a design firm, as most require it.

You can start by earning an associate degree and then move forward with your education based on your goals and your state’s requirements. Keep in mind that to become a certified interior designer, some states require applicants to attend a CIDA (certified interior design accreditation) design school.

Step 2: Apply for Internships

Internships can help you get hands-on design practice and earn the necessary experience to take the NCIDQ exam. If you reside in a state that requires completion of this exam, you’ll need anywhere from 3,520 to 7,040 experience hours to qualify.

In addition to applying for internships, you’ll likely need to work for a design firm or under a licensed interior designer to accumulate enough experience hours.

During this time, you can decide what type of interior design you’d like to specialize in, such as commercial, residential, healthcare settings, etc.

Step 3: Complete the NCIDQ Exam

If you live in one of the 27 states that require completion of the NCIDQ, you’ll need to take and pass this exam before receiving your interior design license. Even if you don’t live in a state requiring NCIDQ certification, completing this exam can increase your chance of being hired by a design firm and help establish your career.

To sit for the NCIDQ examination, you must complete these eligibility guidelines:

  • Earn an Associates degree, certification, or diploma and complete 5,280 experience hours
  • Complete a Bachelor’s or Master’s Degree in another major or an interior design certificate, diploma, or degree and complete 3,520 work-experience hours
  • Complete a Bachelor’s or Master’s Degree and complete 3,520 work-experience hours

The National Council for Interior Design Qualification (NCIDQ) has three parts. The first section is Fundamentals IDFX/IDFX Only. You can complete this portion of the exam if you’re in the last year of your Master’s or Bachelor’s degree program or have met the educational requirements but haven’t yet met the work experience requirements. 

The other two portions of the exam include Professional IDPX and Practicum PRAC. You must complete education and work experience requirements before you’re eligible to take these.

Step 4: Create Your Portfolio

You can begin creating your portfolio before or after completing the NCIDQ. Your portfolio should be full of high-quality photos capturing your best work. You can put your portfolio online if you’re trying to attract your own clients or submit it to a design firm. 

Step 5: Grow Your Business

If you’re working for yourself, build your brand identity, develop a social media strategy, and network at local events. Establishing yourself as a new designer can take time, so the more you network, the better.
