Interior Designers Institute

About Interior Designers Institute

Interior Designers Institute is a small, specialized college rather than a comprehensive university. Its academic identity centers on one field: interior design, extending into interior architecture at graduate level. The college opened in Corona del Mar in 1984 and now operates from a single Newport Beach location. California’s 2024 BPPE report recorded no branch or satellite locations and confirmed participation in federal financial aid programs. The institution’s degree pathway is unusually sequential. The Associate of Arts establishes the design foundation and is a prerequisite for IDI’s Bachelor of Arts. The bachelor’s then advances into larger and more technically demanding residential and commercial work. The Master of Interior Architecture serves applicants who already possess appropriate undergraduate preparation. IDI also offers an avocational certificate, but that course is non-degree and is not eligible for federal aid. Institutional accreditation covers the certificate and all three degree programs through the Accrediting Commission of Career Schools and Colleges. The Bachelor of Arts has additional programmatic accreditation from the Council for Interior Design Accreditation. IDI reports that its programs may be offered in hybrid form to California residents, combining online and in-person study. Prospective students should verify the precise delivery format for their intended term, particularly if they live outside California. This structure is most relevant to applicants who want a concentrated professional-design education. It provides less room for exploring unrelated subjects than a multidisciplinary college, and the bachelor’s pathway depends partly on general-education credit completed elsewhere and transferred to IDI.

IDI’s live admissions page states that applications are being accepted for Fall 2026, with classes beginning September 14, 2026. Applications are handled on a rolling basis. The online application itself has no fee, although a nonrefundable registration charge is due at enrollment. After an application is submitted, IDI says an admissions representative will arrange a personal interview and campus tour. Requirements differ substantially by level. The Associate of Arts requires a high school diploma or recognized equivalent and successful completion of IDI’s introductory certificate course. Entry to IDI’s Bachelor of Arts requires completion of the institute’s Associate of Arts plus 45 quarter units of general education from an accredited institution. Official transcripts are needed to evaluate prior college work, and transferred general-education courses must meet the school’s grade requirements. Master of Interior Architecture applicants need a bachelor’s degree in interior design, architecture, or an equivalent field from an accredited US institution. Graduate review also includes official transcripts and a portfolio demonstrating design competency. Applicants should consult the current program application for its complete submission requirements. International students are accepted, and the 2025–26 catalog states that IDI issues Form I-20 documentation for F-1 students. That catalog required proof of English proficiency, including an internet-based TOEFL score of at least 61, and a certified evaluation or translation for foreign secondary credentials. Because the full catalog expired on July 31, 2026, international applicants should obtain written confirmation that these thresholds remain applicable for 2026–27 before applying.

IDI offers an Associate of Arts in Interior Design, a Bachelor of Arts in Interior Design, and a Master of Interior Architecture. These are not interchangeable entry points. The associate program is the foundation of IDI’s undergraduate sequence and must be completed before entering its Bachelor of Arts program. The master’s program instead requires prior bachelor’s-level preparation in interior design, architecture, or an equivalent area, subject to transcript and portfolio review. The associate curriculum develops residential-design competence through subjects such as drafting, codes, construction, materials, space planning, presentation, and computer-aided design. The Bachelor of Arts moves toward more complex commercial and residential environments, including hospitality, workplace, retail, and health-care contexts. The 2025–26 catalog describes the bachelor’s as a 180-quarter-unit degree. That total includes the associate curriculum and 45 quarter units of general education transferred from an accredited institution; transferable general-education work requires a grade of C or better. The Master of Interior Architecture is a 45-quarter-unit graduate program. Across the programs, the catalog emphasizes simulated professional projects, critiques, field trips, guest speakers, and instruction by practicing designers and architects. Bachelor’s and master’s students may participate in internships with design firms. Campus resources described by IDI include drafting and design studios, exhibition areas, a computer lab, a design library, and a materials collection. The computer facilities support tools including AutoCAD, SketchUp, and Adobe applications. Applicants should evaluate this curriculum as a concentrated professional sequence. Students wanting substantial study in fields outside design will need to consider how IDI’s transfer-based general-education arrangement fits their broader academic plans.

Student Life & Environment

Student life at IDI is organized around studio work and the interior-design profession rather than a large residential-campus environment. The Newport Beach campus provides studios, student exhibition space, computer facilities, a design-focused library, and a room of material and finish samples. These resources support project development, presentations, research, and hands-on specification work. Professional participation is a prominent part of the extracurricular offering. IDI lists student chapters of the American Society of Interior Designers and the International Interior Design Association. Through those organizations, students may encounter professional events, networking, competitions, mentoring, and exposure to commercial-design practice. The catalog also describes guest speakers, showroom or design-center field trips, annual commencement exercises, and internship opportunities for bachelor’s and master’s students. Academic and practical support includes tutoring, technology assistance, disability services, academic advising, financial-aid guidance, and career planning. Students and graduates in degree programs can access job listings and placement guidance; the avocational certificate alone does not provide access to those placement services. IDI does not provide dormitories or other on-campus housing and does not secure accommodation for students. The catalog says the school can provide nearby housing information, but students remain responsible for arranging and financing their own accommodation. Applicants should therefore expect a commuter-style experience and budget for transportation as well as Orange County housing costs.

Location & Surroundings

IDI’s sole reported campus is at 1061 Camelback Street in Newport Beach, in coastal Orange County, California. The setting places students within reach of Southern California design firms, showrooms, manufacturers, and professional organizations. IDI specifically identifies the Laguna Design Center and Stonemill Design Center among nearby industry resources, while cataloged field trips and guest-speaker activities use the broader regional design community as an extension of classroom work. This is not a self-contained residential campus. The college operates from a specialized educational site with studios, computer and library facilities, exhibition space, and materials resources. Because IDI has no dormitories and does not arrange accommodation, students must compare private rental options and plan a commute. International and out-of-area applicants should investigate housing availability, deposits, transportation, and the full cost of living before enrolling. The location may be advantageous for students seeking contact with the Orange County design market, but the practical experience will differ from a traditional university town. Campus tours are part of IDI’s admissions process, giving applicants an opportunity to assess the facilities and commute before signing an enrollment agreement.

Costs & Career Outcomes

IDI’s program costs vary by degree stage, so applicants should not treat one annual tuition number as the price of the entire educational sequence. The live program page lists separate totals for the Associate of Arts, Bachelor of Arts, and Master of Interior Architecture. The last full catalog available during this review was valid for 2025–26 and also separated tuition from registration charges, textbooks, supplies, laboratory fees, and externally completed general-education coursework. Students should request a 2026–27 enrollment agreement and itemized cost sheet before committing. For Fall 2026, the live application page lists a nonrefundable $100 registration fee for each degree program and a $250 international-student registration fee. It also says federal Title IV aid is available to eligible degree-seeking students. Aid may include grants and loans, and borrowing creates a repayment obligation. The non-degree avocational certificate is not eligible for federal financial aid. The school provides a net-price calculator, but individual awards and living expenses will vary. There is no campus housing, so rent, deposits, food, and transportation must be included separately in a student’s budget. Bachelor’s students must also account for the cost of required general-education credits completed through another accredited institution. Career support is available to degree students and graduates. IDI distributes relevant job listings and offers résumé and placement guidance, while bachelor’s and master’s students may pursue internships. Curricular preparation points toward interior design, drafting, rendering, materials or lighting specification, set and exhibit design, and residential, hospitality, retail, workplace, or health-care design. Placement assistance does not guarantee employment, salary, licensure, or a particular career outcome.
