How to Verify an Interior Designer Certification (NCIDQ, State License)
Interior designer credentialing is uneven: roughly half of U.S. states regulate the title “interior designer” or restrict certain design work; the rest do not. The NCIDQ examination from CIDQ is the national professional standard. Verification depends on whether the candidate is claiming a state license, the NCIDQ credential, or both.
Quick answer
Verify the NCIDQ credential at cidq.org → Verify a Certificate Holder. For state-licensed interior designers, verify at the state licensing board (typically housed under the state architecture, construction, or professional licensing department). In unregulated states, NCIDQ certification is the primary professional credential.
NCIDQ and CIDQ
CIDQ (Council for Interior Design Qualification — cidq.org) administers the National Council for Interior Design Qualification (NCIDQ) examination. Passing all three sections of the NCIDQ exam is the standard requirement for professional licensure in regulated states and is the recognized mark of a qualified interior designer nationally.
NCIDQ exam sections
- IDFX (Interior Design Fundamentals Exam): Foundational knowledge; can be taken before completing supervised work hours
- IDPX (Interior Design Professional Exam): Applied professional practice; requires partial work experience
- PRAC (Practicum): Graphic, project-based exam testing spatial planning and building systems knowledge; requires full experience hours
Verify NCIDQ credentials at: cidq.org → Verify a Certificate Holder. Search by name. The portal confirms whether the candidate holds a current NCIDQ certificate.
States requiring interior designer licensure
Approximately 27 states and D.C. have some form of interior design regulation. Requirements range from title protection (only licensed designers can use the title “interior designer”) to practice acts (certain commercial design work requires a licensed designer of record).
| State | Regulation Type | Verify At |
|---|---|---|
| Florida | Practice act; licensed designers required for commercial projects over certain thresholds | FL Board of Architecture & Interior Design — myfloridalicense.com |
| Nevada | Practice act; NCIDQ required for licensure | NV State Board of Architecture, Interior Design & Residential Design — nsbaidrd.state.nv.us |
| New Mexico | Practice act; Interior Designer of Record | NM Regulation & Licensing Department — rld.nm.gov |
| Louisiana | Practice act; Interior Design Board | LA State Board of Interior Designers — lainteriordesignboard.com |
| Alabama | Title and practice act | AL Board of Interior Design — alabamaid.org |
| Washington D.C. | Practice act; requires NCIDQ | DC Department of Licensing and Consumer Protection — dlcp.dc.gov |
For other regulated states, search “[state] interior designer license lookup.” The licensing board is often part of a state architecture or professional licensing authority.
Interior designer vs. interior decorator
These titles are often used interchangeably by candidates but have distinct professional meanings:
| Title | Scope | Credential Required |
|---|---|---|
| Interior Designer | Space planning, building systems, accessibility compliance, construction documents, commercial projects | NCIDQ exam; state license in practice-act states |
| Interior Decorator | Aesthetic styling, furnishings, color, accessories; typically no structural or building-code work | No formal credential required in most states; no standard licensing |
In practice-act states, using the title “interior designer” without the required license is a violation. Verify that candidates for roles requiring a licensed designer of record hold an active state credential.
ASID and professional membership
The American Society of Interior Designers (ASID) is the largest professional membership organization for interior designers. ASID membership is not a license but indicates professional engagement:
- ASID Professional Member: Requires NCIDQ passage or equivalent; most rigorous membership tier
- ASID Allied Member: Non-certified designers; students or related-industry professionals
- IIDA (International Interior Design Association): Alternative professional organization; NCIDQ also used as entry criterion for professional membership
Verify ASID Professional Membership status at asid.org. Note that membership is a professional signal but not a regulatory credential; do not substitute ASID membership for state license verification.
Common red flags
- Claiming “licensed interior designer” in a state with no licensing requirement: Legitimate designers in unregulated states will not claim a state license. Verify what was actually issued and where.
- NCIDQ claimed but not verifiable at cidq.org: The NCIDQ database is comprehensive. Failure to appear is a red flag for roles requiring proven examination passage.
- Partial NCIDQ sections claimed as full certification: Candidates sometimes list IDFX or IDPX passage without noting they have not completed all three sections. Verify full certificate status at CIDQ.
- Degree from non-CIDA-accredited program in practice-act states: Some states require graduation from a CIDA-accredited program as a licensure prerequisite. Verify program accreditation at accredit-id.org.
Verification checklist
- 1. Determine whether the role requires a licensed interior designer of record and whether your state has a practice act
- 2. Verify NCIDQ certificate status at cidq.org → Verify a Certificate Holder
- 3. For practice-act states: verify state license status and disciplinary history at the state licensing board
- 4. Confirm NCIDQ certificate is current (holders must complete CEUs for certificate maintenance)
- 5. For states requiring CIDA-accredited education: verify the degree program at accredit-id.org
- 6. Use VerifyED to confirm the awarding institution was regionally accredited
Verify interior design program accreditation
Interior design degree programs are accredited by CIDA (Council for Interior Design Accreditation). Licensure in several states requires graduation from a CIDA-accredited program. Use VerifyED to confirm the awarding institution was regionally accredited before accepting a candidate's educational credentials.
