Interior Design Certification: Which to Choose?

So you want to become an interior designer, but the certification options feel confusing.

Should you get a certificate, a degree, or pursue licensure? How much will it cost? Which programs actually lead to paid work?

These questions stop people before they even start.

The interior design field has more credential paths than most careers. Some cost $2,000 and take three months. Others require four years and $100,000. Picking wrong means wasted time and money.

This guide breaks down interior design certification options, costs, and outcomes.

You’ll learn what different credentials mean, which programs employers recognize, and how to choose based on your actual goals. By the end, you’ll know exactly which path fits your situation.

What does an Interior Design Certification mean?

Interior design certification opens doors to new skills and career opportunities. It proves you have specific training in design principles and practices.

Some people earn credentials to start their design careers. Others add certifications to grow their existing work. The choice depends on your goals and where you stand today.

Two Common Meanings of Certification:

The term “interior design certification” actually covers two different things.

Certificate programs come from schools and training centers. You complete coursework and get an education credential. These programs teach you the fundamentals. They range from a few weeks to several months. You walk away with knowledge and a certificate showing you finished the program.
Professional certifications require you to pass an exam. You must meet specific requirements first. Organizations like NCIDQ offer these credentials. They show you can meet industry standards. This type takes more time and experience to earn.

Both types have value. Your path depends on what you need right now.

7 Well-Recognized Interior Design Certifications

Different credentials serve different career paths and specializations. Here are the certifications that employers and clients recognize most.

1. NCIDQ Certification (National Council for Interior Design Qualification)

This is the gold standard for professional interior designers. Many regulated states require it for licensure. It proves you can handle both commercial and residential projects.

The exam tests your knowledge of codes, materials, and design documentation. Most designers need years of experience before they qualify to take it.

2. LEED Accredited Professional (LEED AP ID+C)

This credential focuses on sustainable interior design practices. You learn to create environmentally responsible spaces. Commercial clients often prefer or require LEED-certified designers.

The certification covers energy use, material selection, and green building standards. It adds value to your services in the commercial market.

3. WELL Accredited Professional (WELL AP)

Health and wellness drive this certification. You study how interiors affect air quality, lighting, and comfort. Clients who care about occupant wellbeing seek out WELL APs.

The credential is growing fast in corporate and hospitality design. It shows you understand the science behind healthy spaces.

4. NKBA Certification (National Kitchen and Bath Association)

Kitchen and bath specialists earn credentials like AKBD, CKBD, and CBD. These prove your technical planning expertise in two high-value rooms.

The training covers plumbing, appliances, storage, and workflow. Homeowners trust NKBA-certified designers with their biggest renovation investments. This specialty can set you apart from general designers.

5. RIDQC Certification (Residential Interior Design Qualification Council)

This credential targets residential designers specifically. It offers recognition outside the commercial NCIDQ path. The certification validates your skills for home-focused projects.

You don’t need years of commercial experience to qualify. It’s ideal if you plan to work mainly with homeowners.

6. ASID Continuing Education Certificates

The American Society of Interior Designers offers ongoing professional development. These certificates cover ethics, sustainability, and specialty areas.

They help you stay current as the field changes. Many designers use ASID courses to meet license renewal requirements. The flexibility lets you learn what matters most to your practice.

7. Interior Design Certificate Programs (University or Accredited Online Schools)

University extension programs and design schools offer educational certificates. These build your foundational skills and portfolio.

They’re different from professional credentials because they focus on learning, not licensure. Programs vary widely in quality and depth. Look for schools with strong instructor backgrounds and hands-on projects.

How to Pick an Interior Design Certification?

Picking the wrong program wastes time and money. Here’s how to find one that actually matches your goals.

Start with the End Goal

Your destination determines which program fits best.

Hobby to pro: Look for programs that teach business basics alongside design skills.
Freelancing: Choose certifications that include client management and pricing strategies.
Employment: Employers want portfolios and software skills, so prioritize hands-on programs.
Commercial track: Find programs that cover codes, accessibility standards, and contract documentation.

Strong programs cover these core areas.

Critiques and mentor review: Regular feedback from experienced designers improves your work faster.

Is It Worth It to Get an Interior Design Certificate?

It depends on where you are and where you want to go. A certificate makes sense if you need skills quickly for freelance work or a career change.

The investment pays off when you land better clients or jobs faster than self-teaching would allow. But if you plan to work in commercial design or regulated states, a degree often matters more.

Certificates work best for residential designers, stylists, and those adding specialty skills to existing careers. Consider your market, goals, and budget before deciding.

The right program at the right time is worth it. The wrong one wastes money you could spend elsewhere.
