Feeling Positive with the interior design institute
My experience so far has been an amazing one , I remember when starting this course I was just an admirer of interior design without knowing how to actually coming out with a breath taking design, but after submitting my Mudule 10 assignment I can confidently refer to myself as an interior designer without even completing the course yet that just to let you know how impactful this course has been so far.
I will love to also appreciate my tutor miss WENDI she has been so helpful to me throughout my journey by always being there to answer my question where ever I face challenges.

The course content is engaging, informative and well structured. Each module builds on the previous one, creating a logical progression that brings all the key concepts together in the final modules. Nearing the end of the course, I have a clear understanding of how the different elements connect and apply in practice.

I just completed Module 5, and it has been quite a journey! Balancing a full-time job while studying and completing assignments at night and on my days off has been difficult, but I have been learning a lot. The modules are easy to read and understand. My tutor is great; she responds quickly to my questions and helps me a lot with her feedback. The Facebook group is also wonderful because you can relate to others and share experiences. Overall, I’m super happy with this course and would definitely recommend it!

It’s great to know the structured modules are helping you gain insight into the design process, and that having tutor support available is adding to your learning experience.
I have always underrated online learning but IDI changed the way I see things. The course is very comprehensive and the concept building is well thought . The community and social media pages also helped me with relating.What amazed me is the depth to which the assignment goes they search and horn every skill required by an interior design .There is value for money and room for extension if your time lapsed and I have been a beneficiary as well
Just to add I would like to suggest if you could make the modules in Video format also sometimes it may take a while to read but following the video will lessen the hustle as we juggle between work and school .

I get excited when the next module is released, and my tutor Wendi Snyder is fantastic, supportive and knowledgeable and responds to questions so quickly. The experience so far has far exceeded my expectations.

Hi Polly,
We are so pleased to hear that you are finding the content exceptional and that you're enjoying the flexibility of our assignments. It's wonderful that your tutor is providing such fantastic support!
I find the contense to be really interesting. I can't wait for each module to come. I like going on at my own pace with knowing that a tutor is just a click away.
One thing that did overwhelmed me is the programs that one have to use with some of the modules. As I am not very tech savy, I had to learn it from scratch and it does also come with additional costs. Maybe introduce a module earlier that teaches one some of these programs?
But over all, I just love the course and how professional it is.

My experience has been very good. I’ve received very good feedback back on my assignments to make me a better designer. The modules are filled with a ton of great information. This course has grown my confidence in interior design incredibly. Being able to complete a design from start to finish and learning everything I need to complete it well for customers is what it should be. I’m very happy and would highly recommend. Value for the money is perfect.

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.

I feel like this course is very good value for money and the structure I really like it works well with work life balance I like how I can work with my own deadlines but also meet them at a pace so I can finish the course in the 12 months period I’m finding it very straightforward to work with

A Highly Enjoyable and Structured Interior Design Course
I’m about halfway through the course and have been thoroughly enjoying it so far. The online learning platform is very easy to navigate, and the module resources are well structured and clearly organised. To learn SketchUp, I purchased an advanced module and have really appreciated how approachable it is—everything is broken down into small, manageable steps that make it easy to build confidence with the software.
Although it is online and self-paced, it has been great to have an assigned tutor available for support and feedback on assignments. This adds a personal touch and makes the overall experience feel more engaging and supportive.
Overall, I’m learning a great deal about interior design and am excited to continue and complete the course. I would recommend this course to anyone looking to develop their interest in interior design or start a career in the field.

I am really enjoying the interior design course, I am learning so many new things and the modules are so engaging and interesting. I can’t wait to learn what the other modules have in store. My tutor Helen is also a wealth of knowledge and experience and always gives me great feedback and encouragement. I would recommend the interior design institute to anyone wanting to explore the interior design world. 10/10
