It is correct for the school and grade level in a Student Progression Entry to be locked once the student is enrolled in a Mandatory course.  Mandatory courses are linked to students by grade level. Once the student is enrolled, changing the grade level could result in an automatic unenrollment. We do not allow the program to automatically unenroll students.

To unlock the school and grade level in a Student Progression Entry, you must unenroll the student from all Mandatory courses.
