How to Become an Interior Designer: Degree, NCIDQ & Salary (2026)

Updated August 25, 2026 BLS data College Scorecard On this page

Key takeaway: Becoming a professional interior designer generally means earning a bachelor's degree in interior design -- ideally from a CIDA-accredited program -- building a portfolio and fluency in AutoCAD, Revit, and SketchUp, completing supervised work experience under a qualified designer or architect, passing the NCIDQ examination, and, in states that regulate the interior designer title, registering or becoming certified with the state. Interior designers earn a national median annual wage of $67,190 (Bureau of Labor Statistics, May 2025 OEWS national median). Interior decorating, by contrast, requires none of this and is unregulated everywhere in the United States.

Interior design has a clearer professional path than most design fields, because the profession built an accreditor for its programs, a national examination for its practitioners, and a body of state law around the title. That structure is what separates it from decorating, and it is the reason the steps below run in a particular order. The education determines how quickly you can qualify for the examination; the supervised experience is what you accumulate in your first years of work; the examination is what the states recognize.

This guide covers the path as the profession actually runs it, is explicit about which steps are binding and which are competitive, and flags where the rules vary by state and change over time.

Step-by-step: how to become an interior designer

  1. Decide whether you want to design or decorate. This is not a formality. Interior decorating – selecting furnishings, finishes, and styling for existing residential spaces – requires no degree, examination, or license anywhere in the United States, and the steps that follow are unnecessary for it. Interior design – planning space, satisfying codes and accessibility requirements, producing construction documents, and working on commercial projects – is the profession this guide describes.

  2. Earn an interior design degree, ideally CIDA-accredited. The bachelor’s degree is the standard professional credential and the level the Council for Interior Design Accreditation primarily accredits. CIDA-accredited education is the most direct route to NCIDQ eligibility, and many state registration rules are written around it. Career changers who already hold a bachelor’s in another field can reach the same credential through a first-professional master’s. An associate degree supports design assistant and kitchen and bath work and counts toward NCIDQ eligibility with more required experience. Verify any program’s status on the CIDA accredited programs directory, noting whether the online format is covered.

  3. Build software fluency and a portfolio while enrolled. Employers hire junior designers on the portfolio and on demonstrated ability in AutoCAD, Revit, and SketchUp, with the Adobe applications for presentation. The portfolio is assembled from studio work across the degree, and its quality depends on how much iteration each project received. Treat every studio as portfolio material, and take the program’s internship seriously as the first entry on your resume.

  4. Complete supervised work experience. NCIDQ eligibility combines interior design education with documented, supervised experience under a qualified interior designer, architect, or other approved supervisor. The amount required depends on your education: the more interior design education you hold, the fewer hours you need. Internship hours completed during the degree may count toward the total if they are supervised and documented in the required form. Hours accrue on the calendar and cannot be accelerated.

  5. Pass the NCIDQ examination. The exam is administered by the Council for Interior Design Qualification (CIDQ) and is the credentialing examination for professional interior designers in the United States and Canada. It is delivered in multiple sections covering fundamentals, professional practice, and a practicum; the fundamentals section can generally be taken before the experience requirement is complete, and the remaining sections after. Eligibility rules, section structure, and fees are set by CIDQ and revised periodically; confirm current terms on the CIDQ eligibility requirements page.

  6. Register or become certified in your state if it regulates the title. Some states have title acts that restrict who may call themselves a registered, certified, or licensed interior designer, generally requiring a combination of education, experience, and the NCIDQ examination. A smaller number regulate practice itself on certain commercial projects. Many states do not regulate interior design at all. Because this varies and changes, check the specific rules for the state where you intend to work rather than relying on a general summary.

  7. Add specialty credentials as your practice develops. Kitchen and bath designers pursue certification through the National Kitchen and Bath Association. Sustainability-focused designers pursue LEED or WELL accreditation. Healthcare designers pursue specialty certification in evidence-based design. None of these replaces NCIDQ for professional practice, but each carries weight in its specialty.

What degree do you need to be an interior designer?

A bachelor’s degree in interior design is the typical entry credential, and CIDA accreditation is the distinction that matters most within that.

  • An online bachelor’s in interior design is the professional degree: it is what commercial firms hire from, what NCIDQ eligibility is built around with the least required experience when CIDA-accredited, and what state registration rules reference.
  • A first-professional master’s delivers the same professional curriculum at the graduate level to career changers who already hold a bachelor’s in another field, and can hold CIDA accreditation.
  • An associate in interior design supports design assistant, drafting, showroom, and kitchen and bath roles, counts toward NCIDQ eligibility with more experience hours, and can transfer toward a bachelor’s under an articulation agreement.

A degree in a related field such as architecture may satisfy NCIDQ education requirements under CIDQ’s rules; confirm directly. A graphic design degree does not, though the two fields overlap in environmental graphics and branded interiors.

How much do interior designers make?

Interior designers earn a national median annual wage of $67,190 (Bureau of Labor Statistics, May 2025 OEWS national median). Half of interior designers earn more and half earn less; pay varies significantly by specialty, firm size, region, years of experience, and whether you are employed or self-employed. Residential designers running their own practices see the widest variation, and commercial firms generally tie advancement to NCIDQ certification.

For context, graphic designers – the adjacent occupation interior design graduates most often move into – earn a national median annual wage of $62,960 (Bureau of Labor Statistics, May 2025 OEWS national median). The Bureau of Labor Statistics projects employment of interior designers to grow 3.2 percent from 2024 to 2034 with about 7,800 openings per year, and graphic designers 2.1 percent with about 20,000 openings per year (BLS Employment Projections, 2024-34).

How long does it take to become an interior designer?

Plan on roughly six to eight years from starting a bachelor’s to full NCIDQ certification, with the exact figure depending on how quickly you accumulate supervised experience and when you sit for each exam section.

PhaseTypical duration
Bachelor’s degree in interior designAbout 4 years, or fewer with transfer credit
First-professional master’s (career changers with a prior bachelor’s)About 2 to 3 years
Supervised work experience for NCIDQVaries by education; accrues on the calendar after or partly during the degree
NCIDQ examinationSections may be taken at different points; scheduling depends on CIDQ’s exam windows
State registration where applicableApplication review after NCIDQ; timing varies by state

These are ranges rather than guarantees. CIDQ sets the experience requirement and revises it, and each state that regulates the title sets its own application process.

Interior designer vs interior decorator

The distinction is the single most important thing to understand before choosing a program, and it is worth stating in full.

An interior designer plans occupied space. That includes programming a client’s needs, laying out walls and circulation, satisfying occupancy, egress, fire, and accessibility requirements, designing lighting and coordinating it with electrical, specifying materials for performance and safety as well as appearance, producing construction documents a contractor can build from, and coordinating with architects, engineers, and contractors during construction. The work requires formal education, and in regulated states, an examination and registration.

An interior decorator works with spaces that already exist: selecting furnishings, finishes, window treatments, art, and accessories, and arranging them. It is a real skill and a real business, and it requires no degree, examination, or license anywhere in the United States. Decorators do not produce construction documents or take responsibility for code compliance.

The confusion arises because many people use the words interchangeably, and because residential practice sits on the boundary. A residential designer who moves walls and produces permit drawings is designing; one who selects furnishings is decorating, regardless of the title on the business card. If you want the second, this guide’s steps are unnecessary. If you want the first, they are the path.

Frequently asked questions

What degree do you need to be an interior designer?

A bachelor’s degree in interior design is the typical entry credential, and a CIDA-accredited one is the most direct route to NCIDQ eligibility and state registration. Career changers with a bachelor’s in another field can use a first-professional master’s. An associate degree supports design assistant and kitchen and bath roles and counts toward NCIDQ with more required experience.

How long does it take to become an interior designer?

Roughly six to eight years from starting a bachelor’s to full NCIDQ certification: about four years for the degree, followed by supervised work experience whose length depends on your education, with exam sections taken along the way. State registration where applicable follows NCIDQ.

Do you need a license to be an interior designer?

It depends on the state. Some states regulate the interior designer title through registration or certification that generally requires education, experience, and the NCIDQ examination; a smaller number regulate practice on certain commercial projects; many do not regulate the profession at all. Check the rules for the state where you intend to work. Interior decorating requires no license anywhere.

How much do interior designers make?

Interior designers earn a national median annual wage of $67,190 (Bureau of Labor Statistics, May 2025 OEWS national median). Pay varies by specialty, firm size, region, experience, and employment status.

Can you become an interior designer with an online degree?

Yes, if the program holds recognized institutional accreditation and, for the most direct NCIDQ route, CIDA accreditation covering the online format. Firms hire on the portfolio and demonstrated software skills rather than the delivery format. The internship and any residencies happen in person.

Is NCIDQ required to work as an interior designer?

Not for entry-level employment, which is based on the degree and portfolio. NCIDQ is required to use the interior designer title in states that regulate it, is expected for advancement in most commercial firms, and is a prerequisite for state registration where it exists. It is earned in the first years of practice after accumulating supervised experience.
