The SCORM version of the course will allow you to track the progress of your employees. You will need your own learning management system (LMS) in order to do that.
Learning management systems can be downloaded for free if you have technical staff able to configure them. Many LMS providers offer subscription services, and these can be used if you do not have the internal resource required to manage an internal LMS.
Please see the FAQ 'Can I add the course to our organisations learner management system?' for further information on how to request a SCORM file.
