I have been enjoying doing this Interior Design Certification Program and learning a lot.
I have been enjoying doing this Interior Design Certification program as this was my Dream since my childhood. I don't think i could get a better Certification program to do with my schedule and responsibilities. The Interior Design Institute is the best online course. Very good customer service. The material and information they share in the program with examples and images is simple and easy to understand and any question we are guided by the given tutor. My tutor Meghan Yang is the best-
very knowledgeable and experienced in this field, very prompt in replying and guiding me step by step & has a lot of patience. I would highly recommend The Interior Design Institute to those who are interested in this field and want to pursue a career in it.

The course outline and expectations for timelines have been spot on. My tutor has been quick to respond to any questions and always leaves thoughtful and informative comments on my assignments. The student Facebook platform has been great and the international feel from the students inspiring. So far, I am feeling challenged, (in a good way) and learning lots.

Saluters Of The Industry
For anyone embarking a new voyage, that somebody who clears the path is very decisive and indelible. Prospective designers enrolled in IDI can surely witness the lasting influence they can take on to their interior design career. The cutting-edge module content and practice-oriented assignment system allow students to experience a new way of self-learning process. Informative study notes, key attachments, referenced cases and the active website made the online education very efficient. Again, I proudly endorse IDI for anyone envisioning themselves as a designer.

Consider no longer!
The content materials are very in-depth and response is very quick when help is required.
If you want something quick and easy - this course is not for you!
The self-paced learning is a great option and extensions are easily obtained.
I have been working through for some time and looking forward to finalising the last couple of modules.
Would I recommend to other - Yes!
Would I do it again if I had to reconsider - Hell, yes!!

Hi Debbie,
We absolutely love this — thank you!
It’s fantastic to hear you’ve found the course in-depth and that our support team has been quick to help when needed. You’re so right — it’s not a “quick and easy” course, but one designed for real learning and growth, so we’re thrilled that’s resonated with you.
We’re cheering you on as you complete your final modules — and your “Hell, yes!!” truly made our day!
WELL WORTH THE EXPENSE ... EXCELLENT!!
This course provides extensive information on each of the modules. It is most valuable that IDI offers examples from previous students, which assures us that we are on point with requirements for that particular assignment. Useful vendor and other source directories are provided for current and future use. It is great that students are given options on acceptable software platforms for module submission. Both SketchUp and especially AutoCad may require you to play 'catch up' if they are unfamiliar. There is an added bonus factor -- the tutors recommend various blogs to further assist in understanding the concept, rhyme or reason on an assignment. Nice that each module can be revisited for future reference, if need be, and should give one more confidence to proceed into their Interior Design career field endeavors.

Thank you so much for this fantastic review!
We’re thrilled to hear you found the course comprehensive and worth the investment. It’s great that the student examples, vendor directories, and flexible submission options added real value to your experience.
Just to note for future students — while we do support software like SketchUp and AutoCAD, assignments can absolutely be completed by hand as well. We want everyone to feel comfortable working in a way that suits their skill level and experience.
We also love that you highlighted the additional resources and the ability to revisit modules — building confidence as you move into the interior design field is precisely what we hope for. Wishing you every success on your journey ahead!
Highly recommended
I’ve had the most positive experience with the Interior Design Institute. I loved the course, it gives you solid foundations in Interior Design but also encourages you to go beyond. It is professionally made up, comprehensive, practical but also inspiring to open up your creativity. Be prepared that you most probably will need to buy additional modules, if you are serious about it. But the cost of the core course is very reasonable in comparison with other institutions. The administration and organisation is impeccable. My teacher has been very helpful, responsive and encouraging. The customer service replies immediately. So I highly recommend. It’s honest, solid and prepares you well for the profession.

positive experience…
I’ve had a really positive experience studying with the Interior Design Institute. The course structure is clear, professional, and well-paced, and the feedback process has always felt constructive rather than discouraging.
At one point, I submitted an assignment that needed improvement, and instead of simply failing me, they gave me the opportunity to revise and resubmit. That approach made a big difference. It showed that the goal is actual learning and growth, not just ticking boxes.
