The CIDQ Interior Design Professional exam spans 5 domains, and they are not weighted equally. The top areas are Construction Process — 21%, Contracts, Procurement, and Permitting — 28%, Scheduling and Budgeting — 17%. Budget your study hours to match those weights; the full domain list is in the outline section further up this page.

The IDPX exam is CIDQ's official certification test, and passing it earns the Interior Design Certification credential at the Professional level. In career terms, it is verified proof of skill — the kind that moves you up the shortlist when your company works with CIDQ technologies, or when you apply to one that does. The same track also includes NCIDQ Certification, so this exam can anchor a longer certification plan.

You pass the CIDQ Interior Design Professional exam at Scaled score, and each attempt costs USD 350 — fail, and that fee is due again in full for the retake. Treat mock exams as insurance: keep practicing with ActualVCE until your scores sit comfortably above Scaled score twice in a row, then schedule the real IDPX exam.

Please do. ActualVCE offers a free demo download for the CIDQ Interior Design Professional exam — grab it from the product page or leave your email and we will send it over. Purchases come with 365 days of free updates; after that year, extending the update service costs 50% of the original price in your member zone.

The CIDQ Interior Design Professional exam packs 175 questions into 240 minutes. That ratio leaves almost no room for stalling, so time management is a trained skill, not luck. Our suggestion: rehearse full-length timed sessions in the ActualVCE engine, learn to park a question and return later, and walk into the IDPX exam with a pacing plan already rehearsed.

Candidates must have completed education (Bachelor's/Master's/Associate's degree in Interior Design with 60 interior design credit hours, or Bachelor's/Master's degree in Architecture) AND required work experience. IDPX is Part 3 of the NCIDQ Exam. Since CIDQ revises these rules from time to time, confirm the current prerequisites on the official exam page (https://www.cidq.org/for-exam-candidates/about-the-exams) before booking your CIDQ Interior Design Professional exam.

Delivery is effectively instant: your IDPX download link is emailed within one minute of payment, with no cap on how many computers you install it on.

If you fail the CIDQ Interior Design Professional exam itself, the refund policy applies when you took the corresponding exam within 60 days of purchase: submit a scanned enrollment slip and the official Score Report PDF within 2 days after the exam, and the refund is processed within 7 days. Not covered: attempts within 3 days of purchase, exams never actually taken, free materials, and expired orders — and the candidate name must match the payer name. Prefer material over money?
