Files can be destroyed 5 years after a child no longer is served in your district (aged out, graduated, or moved).
When a district intends on destroying files, parents must be notified of the district's actions. The best way to do this is by putting a notice in the local paper.
The notice should be similar to the following statement: "To individuals or the parents of individuals who received special education services through DISTRICT prior to YEAR: all files of students who exited the district prior to DATE, YEAR will be destroyed on DATE. If you want the file, please contact NAME, NUMBER AND/OR EMAIL OF DISTRICT CONTACT".
