Upon satisfactory completion of the course, you have the opportunity to print out a completion certificate that includes a signature. There is no official record of "clock hours" reflected on the certificate, but it takes at least 5 hrs to complete the course. That is a safe estimate.
To generate a certificate you have to have completed each assessment with at least 80% correct or better. Once you complete all of the assessments with a score of 80% or better, you will be prompted to generate a completion certificate.
