Certificate of Interior Design

Accredited Diploma of Interior Design (MSF50218)

A house becomes a home with your skilled touch and creative vision. Our Interior Design courses give you all of the training and skills you need to create beautiful and comfortable homes.

The Interior Design Courses are delivered online and consist of 12 modules and 12 interactive assignments. You can study in your own time and at your own pace. Students studying the Certificate Course are provided up to 12 months to complete their studies. Students studying the Accredited Diploma Course are provided up to 18 months to complete their studies. Extensions are available if required.

The modules are designed to be read sequentially and will help build your knowledge to enable you to design a residential space.

There are exercises at the end of each module which will require you to participate in the design experience. It is through participation and interaction that you will learn to feel confident and find your creative voice. The exercises are designed to help you build your first professional portfolio.

Each student will be given the same residential renovation tasks that will require them to upload new floor and lighting plans, suggest furnishings, fabrics, window treatments, lighting, upholstery and accessories, explore decoration and various design styles, provide colour schemes, upload mood boards, write quotations, prepare newspaper ads, write a scope of works for your contractors, provide a preliminary costing for your clients, etc.

As these are online courses, we understand that some of our students do not have access to real life renovations or clients, so each project completed throughout our course will be hypothetical.

Experience the transformation as your thoughts and opinions evolve while gaining more knowledge and skills. Enjoy the process of gaining skills that will enable you to communicate your untapped creative potential.

Certificate Course of Interior Design

This is a course of very high standards, that is very competitively priced. The course materials are used internationally, and the delivery and format are identical to the Diploma version of the course. The only difference is that the Certificate course is less rigorous and there is no additional impost of Self Directed Study.

Tutors do not have to be Government accredited but have all been handpicked for their industry expertise and ability to impart knowledge to students.

This is a non accredited course in Australia although the course is recognised globally by the following bodies:

- DDA (Decorators & Designers Association of Canada)
- BBB (Better Business Bureau) 
- CID (Certified Interior Decorators International)
- IARC (International Approval and Registration Centre) 
- BAC (British Accreditation Council)
- UKRLP (United Kingdom Register of Learning Providers)

You need a great portfolio, not necessarily a degree in interior design to become a professional interior designer. This is exactly what our Certificate Course focuses on - providing you with the practical skills and technical knowledge to build a professional portfolio and launch a rewarding freelance interior design career or an exciting new hobby.

Diploma of Interior Design (MSF50218)

The Interior Design Institute is owned and operated by Online Education Pty Ltd, a Registered Training Organisation (RTO), enabling us to offer you the Accredited Diploma Course of Interior Design (MSF50218).

Below are some of the key components of our Diploma course:

Accredited with the Australian Skills Quality Authority (ASQA) 
ASQA accreditation requires an extensive and thorough process to verify accredited courses are compliant with current government standards.

More In-depth 
The Diploma modules and their corresponding assignments meet ASQA criteria, are more in-depth (80% different) and better prepare you for entering the workforce at the end of the course.

Approved Assessors 
All of the Diploma tutors are ASQA approved assessors.

Units are integrated through a 12 module course 
The authors have covered the knowledge and performance evidence for all of the units required to be covered by ASQA. The units covered in our Diploma course can be viewed here. These units have been integrated into our 12 module course in a unique and interactive way that allows the student a cohesive and enjoyable journey.

How to study online

All the learning is done online in that when you enrol you receive a username and password, which enables you to log onto our secure student site. From there you can download your first module, which you could liken to your textbook as it contains all the information you will need to complete assignment one. Each module is approximately 90 pages in length and is full of detailed technical information delivered in a friendly, conversational manner that is easy to understand. The concepts are further explained by way of diagrams, images and examples.

Once you have completed your assignment (some are just theoretical, but the majority of assignments combine both theory and fun practical tasks) you then upload it onto our site for your tutor to mark. The tutors will give you a grade (out of 10) and a comprehensive evaluation of your work and ideas and help nurture and improve your skills each step of the way.

What makes The Interior Design Institute so unique is that throughout our courses you have access to the safety net and guidance of the team here at Student Support, who you can contact 24/7. It is not simply a case of giving you a textbook and off you go - far from it.

You also have direct contact with your personal tutor who guides you closely through each step of the course, offering personalised and specific constructive criticism on your submitted work. If you ever have any questions in relation to your course or assignments, all you need to do is send your tutor a quick message and they will reply with an answer as soon as they can.

With this close tutor mentorship, you will feel like your tutor is in the same room as you, and all this can be achieved from the comfort of your own home. That is the beauty of our courses, you can study when you like and at your own pace.

The tutors who work for us are not just teachers, but the best working professionals in their field. By drawing on their knowledge you will gain an edge that will help you realise your true potential.

What do I receive?

You will have the skills and knowledge required to start a full or part time career, a profitable sideline or you can use our course to fulfil an exciting new hobby.

On successful completion of the Certificate Course you will be awarded a Certificate in Interior Design.

On successful completion of the Accredited Diploma Course you will be awarded a Diploma in Interior Design (MSF50218), and graduate as a professional Interior Designer.

Connect with #IDIstudents

We have a Facebook Group that we have exclusively designed for our students. This group contains thousands of our students from across the globe interacting with each other on all topics covered by our courses. It provides a great opportunity for students to meet fellow students from all over the world, ask questions, share knowledge and experience, upload work, give and receive feedback, make new friends and talk everything Interior Design!

The assignments were challenging to say the least as well as rewarding. I felt a sense of great satisfaction completing the assignments as I got to use my creative side, which had been poorly neglected for many years.
