AESOP (Automated substitute finder) Directions

We have the pleasure of notifying you that the Fremont Union High School District has implemented a new automated service that will greatly simplify and streamline the process of recording absences and finding substitutes. This service is called AESOP (Automated Educational Substitute OPerator).

The AESOP service will be available to you 24 hours a day, seven days a week. You may interact with the system either on the Internet or by way of a toll-free automated phone line.

To reach AESOP via the internet, please visit On the website, you will be able to enter absences, check your absence schedule, update personal information, and exercise other features. If you have any questions, concerns, or comments; please feel free to contact Monique Franzino at the District Office at (408) 522-2229 or via email at 

To reach AESOP via phone, simply dial 1-800-942-3767.  You will be prompted to enter your Identification (ID) and PIN numbers, so please have those ready.  For most teachers, your ID number is your personal phone number.  If you are not sure of your ID and PIN numbers, please contact the substitute coordinator at your site. (Please notify the District Office if your identification number is not correct.)  Once you are logged in the system, you will be given prompts for the various menu choices.

Please note: when you access the AESOP system over the phone for the first time, it is very important that you record your name and assignment for substitutes to hear. Please keep in mind that only your name and assignment should be recorded, (e.g. John Doe, Chemistry) as AESOP will play this recording to potential substitutes for all future absences you register. You will not be asked to record this information each time you register an absence.




** When entering an absence, please wait until you receive a confirmation number before you terminate the phone call. Your transaction is not complete until you receive a confirmation number. **
