A manager, but not an account holder, can manage multiple companies. This is useful if you have a lot of clients who want you to monitor their progress.
This is not an automated process - the account holder (or another manager) must choose to invite you (or you can do it when you help them set up their account). The account holder can also remove you at any time.
If you are the account holder and you also want to be a manager with this ability you will have to set up a separate email account. Any Gmail account will do. However, if you already have managers, then they are already ready to manage multiple clients as well as your internal trainees.
If you have multiple companies that you are managing, you will get a pop-up window when you log in so that you can choose which company you want to manage.
To change the company you are managing, log out and log back in again.
Using this option for students:
Manage trainees within your own account (quicker for reports, but you own their account)
If you have students who with you for several weeks then the quickest way of monitoring them all in one go is to use your own account. Simply purchase course licences and assign them to your students. You will be able to see all students' results from your reports page and will be able to click through to view each user profile.
However, if you have students who have purchased their own account, you can have them share their profile with you. This is the same as inviting as a manager.
