This online training should take you about six to eight hours to complete.
The course is self-directed, which means there is no teacher. You complete the course at your own pace. Each module will include a variety of activities for you to check your understanding.
When you have completed the course, take the final self-assessment. This test is similar to the official test that carriers take to get a NSC Safety Certificate. If you pass the final self-assessment, you will likely do well on your certificate exam.
