You don’t have to have any prior educational experience or qualification in business sustainability or environmental science to undertake this course. The Diploma course has been built as a comprehensive, immersive, and foundational course and participants with little to no knowledge of sustainability have successfully completed the course in the past.  

This is a completely online course hosted on a highly user-friendly Learning Management System called Thinkific. With around-the-clock accessibility for 12 months, participants can interact with the course content and learn at their own pace and time from anywhere in the world. 

An important feature that comes with the course is ISS Connect, an engaging community channel accessible to all course participants. You can use this space to interact with your peers, submit your responses to the learning activities of the course, and clear your doubts with the faculty members available on the channel. 

Secondly, an exclusive series of masterclasses are held live online on topics of central importance to business sustainability. These classes led by industry experts will provide you with an opportunity to meet your faculty members and peers in real time and network with them.

Both assessments are in the form of Multiple Choice Questions (MCQs) and participants are marked as per the grading criteria below:

You will have 90 minutes for each assessment (1.5 minutes per question). You need to achieve 50% overall (average of both assessments) in order to pass and qualify for the Diploma certificate.
