Directions for parents to use the codes to create their account and see assignments: https://core-docs.s3.amazonaws.com/documents/asset/uploaded_file/856793/Schoology_-_Parent_Guide.pdf (This document is also on each school's website in the 1:1 Documents folder and contains directions for parents with multiple children.)
***The code is good for each student - so parents do not need separate codes for each course.
