I am currently on module 11 of the interior design institute diploma course. I am enjoying the course & it includes detailed information. I am learning a lot.
My tutor provides thorough feedback on my assignments & is quick to respond to questions.
The only thing I would love to see added is more video content, to break up some of the reading. The module 11 videos have been very helpful & a nice addition to a lot of reading.

Passionate about design...
The interior design institute has been such an enjoyable studying experience. It is a lot of reading, which is to be expected with online study, but it is very easy to reach out to the tutors for assistance. The technical lingo can be difficult to understand at the beginning. I have struggled in some areas and excelled in others, but overall the structure is very easy to follow and I feel I am getting good value for money. Knowing CAD beforehand can be very beneficial but the course has been instrumental with teaching me in the ins and outs of SketchUp. I would recommend this course to anyone who is passionate about design.
The only improvement I could recommend would be more videos for those of us who are visual/audio learners over reading learners.
My favourite part has been learning the historical aspect of design and how it has influenced and continues to influence design choices.

Hi Amanda, thank you for your thoughtful review! We’re so pleased to hear that you’ve had an enjoyable learning experience and are finding good value in the course. It’s great that you highlighted both the challenges and strengths along your journey — design terminology can definitely feel like a new language at first, and it’s wonderful to hear that you’ve been building confidence along the way.
We also appreciate your feedback around additional video content for visual and audio learners, and we’ll certainly pass this on. It’s fantastic to hear that learning the history of design has been a favourite part for you — understanding where design movements come from can add such a meaningful layer to creative work. Wishing you continued success with the rest of your studies!
All-in-all I'm pleased with the experience and think it's great value for money!
I've been loving the fully online, self-paced studying experience that the Interior Design Institute provides. Having a knowledgeable tutor assigned to you is very helpful for any questions and I have always gotten responses in a timely manner.

Advanced modules are great
Advanced modules are great
I have taken advantage of completing some advanced modules as part of my study and will continue to add more. It is great to have access to these courses within the Institute so additional enrolments are not required- particularly if you want to specialise in certain areas of design. It offers a layer of confidence once you graduate.

Interesting, flexible, practical and enjoyable!
This course is very thorough, the modules are easy to read, not too heavy, and written in a way that keeps you interested as it builds through the different modules. The assignments are explained well, often with examples so you know which way to head. I started this a long time ago, but have had periods of time when life and family and other work have just got too hectic and I didnt have the headspace. Being able to extend the course has been fantastic, and Im now almost finished. Its going to feel great to get there and I have learnt so much. The last few modules really get you thinking about how you are going to set up your business and I have found them very practical, with lots of notes to print out and keep to refer back to when I am in business.

Life can definitely get busy, so it’s wonderful to know the flexibility and extension options made it possible for you to keep going and now be so close to finishing — that’s a big achievement!
We’re especially pleased that the final modules are helping you think about setting up your business in a practical way. Those are such important steps, and having resources to refer back to can make all the difference.
Wishing you all the best as you complete the course — you’re nearly there! 😊

Diploma course review

I have loved every bit of the assignments and studying! It has been brilliant for me to study at my own pace as I am still working full time as a teacher. The content is fabulous and the expectations are high, which is great.
If there were anything I’d like to see more of, it is maybe a register of people willing to teach or demonstrate Sketch Up and Layout in person in your local area, or even like a virtual meeting. As the only challenge I have found is trying to navigate learning these programs with written information - I think I would understand and learn more if I could see someone demonstrating and showing me.
Overall, I am so excited about this Diploma course and I am so pleased with the confidence it has given me.

Hi Nicole,
This was such a lovely read—thank you for sharing it! It’s great to hear how much you’ve been enjoying the assignments and that studying at your own pace has worked so well alongside full-time teaching. That’s no small feat, and it’s wonderful that the course is meeting you at that level.
We completely understand how challenging it can be to learn programs like SketchUp and Layout through written materials alone—it’s a very common experience, and many students feel the same way. At the moment, we don’t have a system in place to connect students with local tutors or live demonstrations, but we truly appreciate you sharing this idea. It’s helpful for us to hear where additional support could make a difference, and we’ll be sure to pass your feedback along to the team.
It’s so good to hear how much your confidence has grown—that’s exactly what we hope for. We’re really excited for you as you continue through the Diploma!
