Exam Format 

The exam is a three-hour fifteen minute computer-based exam. The exam is an integrated case study. Each exam will comprise of a series of exhibits of information and three tasks each containing several requirements:  

•    Task 1 will consist of requirements related to Syllabus Area B  
•    Task 2 will be focused on Syllabus Area C  
•    Task 3 will be based on Syllabus Area D   
 
The frameworks and regulations covered in Syllabus Area A are underpinning knowledge for the whole exam, but the ethics covered in Syllabus Area A will be specifically examined. Ten marks of the exam will be focused on ethics, and these will be split across any two of the three tasks. Therefore, the three tasks within the diploma assessment will be worth 30-35 marks each. 
 
The requirements within each of the three tasks will be a mix of computational and discursive activities. All requirements and tasks are compulsory. The overall pass mark for the Professional Diploma in Sustainability is 50%.
