Answer : Unlike the profession of design architect, most interior designers do not have five or more years' worth of supervised experience. To become a registered architect in any state in the U.S., it is necessary to receive certification through one's respective board (or architectural exam)
Additionally, it usually takes many years to learn and memorize all the legal code restrictions for each type of building-a process that is made easier by passing an examination upon completion. The architectural certification requirements are overseen by The National Council of Architectural Registration Boards (NCARB).
In order to be eligible for NCARB Registration as an Architect candidate, one must meet education prequalifications and then pass specific exams.
