The flexibility has allowed me to complete this course along side my current job and busy schedule with young kids. The modules and assignments are full of useful information. Had to try a few of the recommended programs for creating a floor plan before I found one that worked for me, so more guidance through that piece would have been helpful. Otherwise having a great experience!

Hi Kara 😊
Thank you so much for your lovely feedback! We’re really glad the flexibility has worked well for your busy schedule and that you’re finding the modules and assignments useful.
Just to add on the floor plan software point—using specific programs isn’t compulsory, as students are absolutely welcome to hand-draw their floor plans if they prefer. That said, we completely understand your experience, and we appreciate the feedback about wanting more guidance there.
If you ever need support, our tutors are always here to help 💛
I have really appreciated the self-paced nature of this course since I work full time. The modules have been very thorough and informative while not being overwhelming
I also really enjoy and appreciate the feedback and support from Khamille.

A solid introduction to interior design, but not as complete as expected
I enrolled in the Interior Design Institute course with high expectations. I am currently halfway through the program, and my experience has been mixed so far.
The course material is clear and structured, but it is entirely reading-based. Personally, I expected more video support or recorded explanations from designers to help reinforce the learning process. While this may not be essential for everyone, it would make the course feel more complete.
I also found the tutor support somewhat limited. While working on the floor plan assignment, I sent two emails for clarification, and the responses I received were brief and did not fully address my questions. I eventually had to rely on friends for help to complete the assignment.
Another challenge is that students without prior experience with design software such as SketchUp may find it difficult to keep up, as there is little technical guidance provided.
That said, the course is not bad. It provides a good foundation and useful structure for beginners, but, in my opinion, it could benefit from more interactive teaching resources and stronger engagement with tutors.
Overall, I still believe the program has value, but it did not fully meet the expectations I had when enrolling.

Thank you so much for sharing your honest feedback—we really appreciate you taking the time to do so.
We’re glad to hear that you’ve found the course material clear and structured, and we completely understand your thoughts around wanting more interaction and deeper tutor guidance. That kind of feedback is incredibly valuable to us as we continue improving the learning experience.
For any students who may feel the same, we do offer a few additional ways to feel more supported throughout the course. Our student community (including the Facebook group) is a great space to connect with others, ask questions, and share work, and we also run regular live virtual workshops where you can interact in real time. We also share helpful video resources, which many students find really useful alongside the modules.
And of course, tutors are always available via the messages tab if you’d like more guidance or clarification at any point.
We’ve also reached out to you directly to better understand your experience and help resolve any concerns.
Thanks again for your feedback—it truly helps us grow and better support our students 🤍
The instruction provided by the Interior Design Institute has been incredibly helpful in my first years of interior design work. What I’ve learned so far has been well worth it, and I truly appreciate when my trainer is detail-oriented and gives criticism on how I can improve. I look forward to completing my final modules and would highly recommend this course. Khamille Joy has been an amazing teacher, and I always look forward to hearing her instruction at the end of each module.
I loved learning to create mood boards, and I incorporate these at my job almost every day.

We’ll be sure to pass along your kind words to Khamille as well — she’ll be delighted to know her guidance and detailed feedback have made such a positive impact on your learning experience.
Wishing you all the best as you complete your final modules — we’re excited for what’s ahead for you! And remember, we’re always here if you need any support along the way!

The experience has been great. I’m really enjoying both the material and the projects. It’s interesting, and the best part is that it’s very hands-on. The program covers a broad spectrum, so I’m learning many different aspects of the industry, which I love.
The more challenging part is the technical side; learning new programs and figuring out how to use them to complete projects. But when it comes to the actual interior design content, it’s been fantastic.
Reply from The Interior Design Institute2026-04-06
Thank you, Sarah, for sharing your experience. We’re so glad to hear you’re enjoying both the material and the hands-on projects, and that the course is giving you a broad understanding of different aspects of the industry. It’s completely natural to find the technical side more challenging when learning new programs, but it’s great to hear you’re finding the interior design content so rewarding. Keep going—you’re doing wonderfully! 😊
Quite a challenging course. Interesting enough content, each assignment takes a great deal of time and motivation.
Personally, I’d prefer a little more personalised guidance.

Thank you, Sinéad, for sharing your honest feedback. We’re glad you found the content interesting, though we understand that the assignments can feel quite demanding and require a lot of time and motivation. We really appreciate your thoughts on personalised guidance—please remember that your tutor is always there to support you, and you’re very welcome to reach out through the message tab for more tailored help. Our team is here for you every step of the way, so don’t hesitate to get in touch whenever you need a bit of extra guidance. 😊
I would like more video material and more technical information. The modules do not contain all the symbols used in the industry. A little disappointing when one has to complete assignments.
Reply from The Interior Design Institute2026-04-06
Thank you so much for your thoughtful review and for taking the time to share your feedback with us — we truly appreciate it, Mariska.
We completely understand your comments regarding the need for more video content and more technical depth. We’re currently working on a full rewrite of this module, which is scheduled for release within the next month or so. While we realise this won’t directly benefit you now that you’ve completed the module, your feedback is incredibly valuable and is helping shape these improvements.
Regarding the symbols, this is something we approach very carefully. Industry symbols can vary quite significantly from country to country, which makes it challenging to include a single “universal” set that applies everywhere. For this reason, we always encourage our students to supplement their learning with additional local research to ensure they are aligned with industry standards in their specific region.
We really appreciate your input — it plays an important role in helping us improve the course for future students. Thank you for your feedback!
This course fits perfectly with my random schedule! It’s very in depth and my tutor is knowledgeable and thorough with her feedback!
Reply from The Interior Design Institute2026-04-06
We're happy to hear that our course suits your schedule, Jodie. It's great to know you find it in depth and that you appreciate the tutor's knowledgeable and thorough feedback!
The most important advantage of this course for me is that it is self paced. I can complete the modules at my own time, whenever it suits my schedule. The modules are well designed and the assignments at the end of each module motivate me to improve and make my own research that will be useful in real interior design projects. So it is not just theory. I would definitely recommend this course for aspiring interior designers.
