It's a really good course
It's a really good course, concise and informative with fun assignments. The only draw back is accessibility to tutors, and I would prefer to fix errors in assignments before getting a pass to make sure I've done things correctly.

Thank you so much for your kind words—we’re really glad to hear you’re enjoying the course and finding the assignments engaging 😊
We completely understand your point about wanting to correct any mistakes before receiving a pass. Just to clarify, our course is designed so that assignments are treated similarly to exams, which means tutors aren’t able to provide feedback prior to submission. That said, if your tutor feels an assignment hasn’t been completed to your full potential, they can reset it and give you the opportunity to review and improve your work.
We really appreciate you sharing this feedback—it helps us understand what matters most to our students 💛
Loving the course!
I am so pleased I decided to start my interior design journey with IDI. I am currently half way through the course and so far the modules have been really interesting and thorough.
The best part for me is that it is all online and at my own pace, so I can fit my studies into and around my schedule. I’m looking forward to the next half of the course and would highly recommend to anyone!

Half way through and really enjoying it
I'm half way through the diploma course with the Interior Design Institute and it's been wonderful so far. The course is easy to follow and is very in depth. There is lots of reading but I don't mind this. I had previously studied a certificate in interior decor with a local university to me but this course with IDI is much more detailed and challenging. I love that I can do it during my own time (I have a 4 year old and work part time). The content is easy to follow, even for beginners and it has lots of practical examples. I haven't got bored at all. The assignments have been enjoyable and challenge you on what you have learnt. I also decided to take the advanced sketch-up course which has also been really enjoyable and already eyeing up a couple of others I want to do next.
The online community on facebook is also very supportive. It’s nice to be part of a an encouragement and supportive group and to share ideas.
Highly recommended this course if you are wanting to learn more about interior design.

The course has been wonderful
The course has been wonderful. I have enjoyed it.
I would have preferred having a few classes live, online to attend. Doing it online, was great, in my own time, was wonderful. But I really missed the interaction with a teacher and other students. I did ask for help on the threads, but really didn't get any and I did speak to my tutor, quite a bit, and that was very good, but again, It felt so very remote, I found that very challenging.
Lastly, I did see that there were more classes I could attend but as they were quoted in USD, it put them out of my reach.

Hi Noeline,
Thank you so much for taking the time to share your experience with us. We’re really glad to hear you enjoyed the course and appreciated the flexibility of studying online and in your own time.
We completely understand your feedback around missing live interaction. While our courses are designed to be fully self-paced, we know that real-time discussion with tutors and fellow students can make a big difference for some learners. We’re glad to hear your tutor support was helpful, even though the overall experience still felt a little remote for you — thank you for sharing that honestly.
Regarding the additional classes you mentioned, we just wanted to clarify that these are optional workshops, not part of the core course. They are offered in USD so that students from all over the world can access the same sessions, but participation is entirely optional and not required to complete the course.
We truly appreciate your thoughtful feedback, as it helps us continue improving the student experience. Thank you again for being part of our learning community, and we wish you all the very best moving forward!

Self-Paced, Practical Learning
I have been studying Interior Design through the Interior Design Institute for a year now and it has been an incredibly valuable experience. The course has given me a strong foundation in residential design, space planning, materials, and finishes. I have gained practical skills in client communication, concept development, and project coordination, which I have applied in real-world projects. The program is structured, engaging, and has significantly strengthened both my technical and creative abilities.
