A Diploma course can take approximately 12 months to complete if studying full-time, Certificate IV courses can be as short as 10 months full-time, while you should expect around 18 months to complete an Advanced Diploma. The duration of your qualification also depends on how many hours you put in each week to study. However, at CAL all students are offered a generous 24-month enrolment period to complete their Compliance and Quality Auditing qualifications at their own pace.
