Quite a challenging course
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. 😊
Great experience
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.

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! 😊

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.

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!

Thank you, Zakhe, for your kind feedback. We’re delighted to hear that you found the course well organised and reliable, and that our tutors have been professional and supportive throughout your learning. It’s also great to know the modules were easy to understand and apply. We truly appreciate your recommendation! 😊
Study at your own pace
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.

I’ve had a great experience with the Interior Design Institute so far. I’m currently finishing Module 10, with only two modules left, and I’ve learned a lot.
The course is well structured, easy to follow, and flexible to study at your own pace. The assignments are practical and really help apply what you learn.
I would definitely recommend this course to anyone interested in interior design.

Practical & Purposeful
The Modules are really in depth & extensive, whether you have been in the industry already or completely new. The assignments are really good at using and applying knowledge learned - really well balanced. The course teaches you the information without pushing you in a certain design direction, allowing you to find your own feet.

I would like to make a brief observation regarding the ability to differentiate between concepts. One detrimental aspect of the options is the lack of sufficient explanations, and in some parts, the explanations are inadequate, making it difficult to fully grasp certain concepts.
I hope this will be taken into consideration to improve the quality of educational content.

Increased my confidence, competence and appreciation
I appreciated the material in this course. I am self taught, read a lot and worked with other fellow designers and gained a lot of experience in these ways. However, taking this course has given me a lot more confidence, skills, tools and resources that I did not gain on my own. I discovered a lot more through the course. It makes me feel more prepared for the real world. In my opinion, self-control and self-motivation is vital to start and finish this course, a lot of reading is involved. It’s definitely within the reach of the average person to accomplish. Because of time and management I had to purchase another 12 months to finish it. My tutor has been great and responsive. I continue to recommend this course to people
