It should be addressed in the court order, this is not the same as having joint legal custody. The grandparents now have sole custody, care and control of the child. Parental access needs to be addressed through the court. Some of the information can also be accessed at the annual review of the guardianship where the guardians must update the court as to the child's progress including progress in school.
Under the Individuals with Disabilities Education Act (IDEA), the term "parent" is defined. Under the facts outlined in your scenario, the grandparents are considered the parents for purposes of education matters, including access to education records. Your wife would not be considered the "parent" for purposes of accessing the children's educational records. Until something changes, such as her parental rights are reinstated by the court, then she will not be able to access the educational records.
