On average, the course takes about four to six hours to finish. Most learners complete a few lessons at a time, and the course will save their progress through the last lesson they completed. After users complete the course, they will always have access to it, in case they want a refresher.
As noted in the National Industry Standards Guidelines and Code of Ethics:
“Recommended Benchmark: Optimally, the time allocated for comprehensive, effective delivery of pre-purchase curriculum to achieve a desired expected outcome and cover content adequately is eight hours of education. In some circumstances (e.g., based on pre-assessment of learners’ needs) hours may vary, but in no case would less than four hours be sufficient”
