Student Activity Guide - Assign Tasks

When setting up a recurring Process Scheduler job to Assign Tasks in Task Management, does the process not assign a task that has already been assigned to the student, or does the Pop Select PS Query need to check if the task has already been assigned? (Campus Community > Task Management Work Center > Manage Tasks > Assign Tasks)

We are on CS 9.2 PUM 21, PT 8.58.

Thanks!
