Please note: this is a FIRST COME, FIRST SERVED service and space is limited – the time that you complete the form will establish your position on the bus list.

Important:  The form linked above is to get information on preferred stop requests. Please do not make a payment until you receive an invoice from the school. Once bus assignments are made, the school will invoice families. Invoices will be sent on or around August 1, with full payment due on August 15 in order to ensure your seat. 

The fees for the 2024-2025 school year are as follows:

  • Standard fees: $300 for one child, or $250 per child for families with more than one child riding the bus. 
  • For families that qualify* as low income per Community Eligibility standards the fee is $50 per student.

*Qualification is based on state records updated in August. You will be verified by the school and qualification reflected on the invoice.

The invoice will include information regarding payment deadlines. Unmet invoice deadlines may result in foregoing the seat.



Many families carpool to IACS. The school has a form to help families find each other for car pooling. To learn more, please review our Carpool Flyer. This flyer will explain the process and allow for sign up.
