  • Course - Separate Exam: This option is the same as course but includes an option to challenging the test only.  Those who choose to write only the test will receive no instructor support so studying is important. When registering, please indicate your choice.  
  • Refresh and Write: Quick one hour presentation highlighting important changes in regulations and / or best management practices followed by the test. Studying prior to this course is essential. Suitable for people who are recertifying and those who are independent learners.

All modules are available on the first day.   It is recommended to complete one module per day with answers submitted by 11 pm. You can work ahead if you like. Once an assignment or test is submitted, you no longer have access to make changes to your answers.
