Hi Lisa,
Thank you so much for your lovely feedback! We’re thrilled to hear you’re enjoying the course and finding the foundations of interior design engaging and clear. Wishing you continued inspiration and success as you progress through the modules! 🌟
Comprehensive course with great support
The Diploma of Interior Design provided by IDI is a great course! It is very comprehensive and well laid out and as a result gradually builds your skills and confidence in the interior design industry. My tutor, Linda, is fabulous, she is always on hand if I have questions, as are the administration staff who support the course. If you are looking for a well run online design course that covers all the industry requirements, for a fraction of the price as elsewhere then look no further; I highly recommend IDI's Diploma of Interior Design!

The content is easy to understand and visually great! It can be difficult to keep the momentum when doing it alone, some sort of group chat on the platform would be great or an easier way to ask smaller questions? The self paced nature makes it so good for those people who have to work. Thank you!

Hi Kayla,
Thank you so much for your thoughtful review! We’re really glad to hear that you’re enjoying the course content and finding it easy to follow and visually engaging. It’s also wonderful to know that the self-paced format is working well alongside your work commitments.
We completely understand your point about maintaining momentum when studying independently. While the course itself is self-paced, we do have a student Facebook group where many students connect, share experiences, and support each other during their studies. We also appreciate your suggestion about having an easier way to ask smaller questions on the platform — feedback like this is very helpful as we continue looking at ways to improve the student experience.
Please remember that our Student Support team is always here if you have any questions along the way — big or small — and we’re always happy to help.
Thanks again for sharing your experience, and we wish you all the best with the rest of your course! 😊

Loved it
I am almost finished the course and have loved each step. I especially enjoyed learning how to properly make sample and material boards. The sketch up advanced module, while frustrating, was also very fun to learn. I will say it is a pretty lengthy program and would be prepared for it to take longer than anticipated,especially if you are also working full time as I was. The only thing I would have appreciated is having a live tutor for the sketchup extension module. It was very hard to explain issues and questions I had about sketchup over email.

Hi Brit,
Thank you for sharing your experience. We're so pleased to hear how much you’ve enjoyed the course and especially that you found the sample and material board lessons valuable. It’s great that you also had fun working through the SketchUp Advanced module, even with its challenges.
We also appreciate your feedback regarding live tutor support. Our tutoring is provided via the messaging system so tutors can review questions carefully and provide detailed guidance, but we completely understand that technical topics like SketchUp can sometimes feel easier to discuss in real time.
Congratulations on being so close to finishing the course, and thank you again for your thoughtful feedback!
Assignments reinforce the concepts taught
The assignment in each module requires the student to apply the information learned. These assignments are often quite hard because it sounds easy while reading it but the application of the concepts is where the learning occurs.

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.
