Administrators cannot add new students to teacher rosters through the administrator dashboard. However, the administrator dashboard does allow administrators to login to their teachers' dashboards.
New students will need to be added to classroom rosters by the teachers themselves. A new student will not be able to practice on Front Row until the teacher has added him or her to the roster. This can be done prior to the student arriving at school or at the beginning of a Front Row practice session.
