Allen ISD uses an automated system that logs employee requests for substitutes known as "AESOP."  Teachers may login to AESOP to request a sub as soon as they know one is required.  Approved substitutes will be called automatically when their attendance is requested. 
If you are interested in becoming an approved substitute in Allen ISD, please fill out an employment application online to apply to become a substitute. 
All employees will use the same log-in screen to access the program.  Use the link below to enter AESOP.
