The Spark license is activated as soon as the learner accepts the invitation to join an organization. Once activated, the learner appears as a member of the organization, and his activity on the platform can be monitored by the manager and administrators.
If a learner starts one or several courses before joining an organization, his progress data for those courses will not be visible in the analytics.
The learner will have access to his progress status on the courses he has taken as well as his certificates from his individual dashboard, but the managers and administrators will not have access to these if the courses were started before the Spark license was activated.
Any progress in a course that was started before the activation of a Spark license will not be visible in the analytics, even if the course is completed after the learner has joined the organization (the start date of the course is what is considered in this situation).
