Professional requirements for interior designers are not identical across the United States. Each state decides whether and how interior design is regulated.
Kinds of rules
Depending on the state, rules may restrict the use of a title such as “registered interior designer,” may regulate the practice of interior design in certain building types, or may leave the field largely unregulated. Some states recognize NCIDQ Certification as part of their requirements; the details differ and change.
Related but separate: architect licensure
Architect licensure is a different regime administered by state boards and coordinated by NCARB. Interior architecture degrees do not automatically lead to architect licensure.
How to check
Contact the state board or regulator directly and read the statute or rules. Professional associations such as ASID and IIDA publish advocacy and regulatory information, and CIDQ publishes information on how NCIDQ Certification is used. Confirm everything with the state authority, because this site does not provide legal advice.
What this directory does and does not say
Program pages never state that a graduate is eligible for registration or licensure in any state unless an official page for that program says so, and then we quote exactly what it says.
