Pathways includes a read only teacher portal that allows you to provide per-teacher access to placements, students and classes. The teacher can only access placements and classes for their linked school, and access is read-only.
To find a teacher's auto generated username and password visit the Schools link up the top of Pathways and choose a school. From the teacher list on the right you will see the teacher listed (or you may need to add them).
When you click on the teacher's name the edit screen will open at towards the bottom note the username and password is listed in blue. The little refresh button next to the password reset the password to something new.
