Co-teachers are able to view student data (but are not able to modify and of the module setup) for any classrooms that they have been invited to be a co-teacher in. In order to become a co-teacher, you must be invited to become a co-teacher from the teacher who created/owns the classroom.
You can ask the teacher to follow these instructions to add you as a co-teacher.
Note: If you are an administrator at the school and need to be added as a co-teacher for multiple teachers are your school, you can email us at alwaysgrowing@sowntogrow.com and we can process your request after we verify your administrator status.
