Learning plans  

All current Unity users will be able to log in to the On-Demand Training platform and view the course catalog, course description, course modules, duration, and skill level. Once a subscription is activated, each user will also be able to enroll in Learning Plans, which are collections of courses curated for  learners who require a broader subject matter expertise, specific to their  industry.  Learning Plans ensure that each learner is taking the right courses in the right order, so that they can get the most out of the time that they are dedicating to the platform.
