Interior designers plan and arrange the internal spaces of buildings to be both functional and beautiful. They select furniture, colors, materials, and layouts that match a client's needs and aesthetic preferences. Day-to-day work includes sketching designs, sourcing furnishings, managing budgets, and coordinating with contractors and architects. Some specialize in residential homes, commercial offices, hospitality venues, or specific design styles. They balance practical requirements like traffic flow and lighting with the client's vision and budget constraints.
Licensed interior designers are regulated at the state level. Every state sets its own education, exam, and experience requirements.

Most states require a national or state-administered exam covering interior designer knowledge, ethics, and state law.
You'll take two parts. The national section covers design principles, codes, and practice standards across all states. Then you complete a state-specific portion on local laws and regulations. Most states contract with testing companies like PSI, Pearson VUE, or Prometric to administer the exam. You answer multiple-choice questions on both sections. Each state sets its own passing score, typically in the 70 to 75 percent range. Plan to study 100 to 150 hours before test day.
Continuing education is required between renewals in almost every state. Hours and topics vary by board.
Interior designer licenses require ongoing education to renew. Your state board sets the specific hour count and topics. Common requirements include ethics training and updates on state regulations. Check your state board's website for exact CE hours and deadlines before your renewal date arrives.
Strong candidates for the interior designer role combine the technical knowledge tested on the exam with judgment and communication skills you build through supervised experience.
You'll need both technical precision and genuine people skills to succeed as an interior designer. The exam tests your knowledge, but your real work happens in conversations: listening to what clients actually want versus what they think they want, explaining why your design choices matter, pushing back respectfully when needed. You'll spend time in front of clients, contractors, and vendors. Your judgment matters constantly. Can you make fast decisions with incomplete information? Do you stay calm when a material gets discontinued mid-project? Those skills matter as much as knowing building codes.
Practicing as an interior designer without an active license is illegal in every state. Typical penalties include civil fines, forfeited income, and in some states criminal charges on repeat offenses.
Practicing interior design without a license is illegal across all 50 states. Unlicensed work carries civil fines and requires forfeiture of any income earned from those projects. States vary in their enforcement severity. Repeat offenders may face criminal charges, though sentences are typically short. The specific penalties depend on state law and violation history.

You'll follow a five-step path in most states. First, complete accredited education. Then pass a national or state exam. Next, gain supervised experience under an established professional. You'll undergo a background check before licensure. Finally, complete continuing education hours before each renewal. The exact requirements shift by state: education hours, degree levels, and experience timelines all differ. Check your state's board for precise minimums.
