What to expect

ISCD’s Certificate IV in Interior Decoration course will give you a solid understanding of interior design foundations and interior design principles over 2 study blocks. You’ll learn the principles of colour theory, furnishing choices, how to consider space while designing, and how to construct and present your designs on professional-grade software, such as Adobe Creative Suite and SketchUp.

Design Software ToolKit

We know how important it is to access the latest interior design software, so we’ve designed this course so you get hands-on experience using these tools from the moment you begin. This software enables you to communicate innovative ideas seamlessly, so you’ll graduate knowing how to confidently pitch and present in the digital space. The Cert IV in Interior Decoration includes the software below as part of your tuition fee, so you won’t be required to purchase any additional software. You’ll be introduced to more complex design software tools as you progress through the course.



Programa: the ultimate specification, project management, and collaboration software for interior designers and architects.
Adobe Creative Cloud: a comprehensive suite of design software that empowers designers to bring ideas to life.
SketchUp: a versatile 3D modelling software designers and artists use to create detailed and realistic digital representations.
