ZESBI Now Open!

The Zero Emission School Bus and Infrastructure (ZESBI) incentive project is now open for applications.  ZESBI’s initial application window opened on May 14, 2024, at 10:00am Pacific Time.  The application link is available at:

A total of $500 million is appropriated by Senate Bill (SB) 114 for ZESBI incentives, pairing zero-emission (ZE) school bus vehicle funding through the California Air Resources Board (CARB), with charging infrastructure funding through the California Energy Commission (CEC). In Fiscal Year 2023-24, $375 million is allocated to support the replacement of old internal combustion school buses with ZE school buses and $125 million is allocated to support infrastructure and associated cost incentives.

​​​Applicant Eligibility
Eligible applicants include California Public School Districts, California Public Charter Schools, California Joint Power Authorities, and California County Offices of Education. Charter schools classified as a non-classroom-based charter school as of FY 2021-22 are not eligible entities. All applicants must serve students within the K-12th grade levels and own their own school buses.  

Participation in ZESBI requires the scrappage of an old school bus for each new zero-emission school bus that is awarded.

Applicant Prioritization

Applicants within each tier (Tiers 1 – 3) will be ranked based on the timestamp of submission of their complete Application Part A. The timestamp on any application that is missing materials or otherwise deemed incomplete will not be recorded until all application materials are submitted.   

Please refer to the Local Educational Agency Prioritization List to identify an applicant’s priority tier.  If you cannot locate your Local Educational Agency name, please contact for help in determining tier designation.  

How to Prepare for Application
Eligible applicants interested in applying should be prepared to provide the following at time of Application Part A: 

  1. A Letter of Intent signed by an authorized representative stating the applicant’s intent to purchase zero-emission school bus(es).  A Letter of Intent template is available.
  2. A current copy of the DMV registration for each old school bus included in Application Part A. 
  3. A current copy of the CHP Safety Certification (CHP 292 or equivalent) for each old school bus included in Application Part A. The old school bus(es) must have a current, unexpired, CHP 292 or equivalent at time of application submittal. 

Please review the Application Information Session recording for a more detailed explanation of the application process.

Presidents Message

Presidents Message: Summer 2024

As we reach the end of another school year, I want to extend my heartfelt gratitude to each and every one of you. Your dedication, professionalism, and unwavering commitment to safely transporting our students have been truly exceptional. This year, like every year, you have gone above and beyond to ensure that our children have reliable and safe access to their education, and for that, we are immensely grateful.

As summer break approaches, I encourage you to take this well-deserved time to rest and rejuvenate. The work we do is demanding and often comes with challenges that require our utmost attention and energy. It’s crucial that we use this period to recharge our batteries, spend quality time with our loved ones, and engage in activities that bring us joy and relaxation.

Whether you are planning a vacation, enjoying a staycation, or simply taking a few quiet moments for yourself, I hope you find the peace and relaxation you deserve. Remember, taking care of ourselves is just as important as taking care of our responsibilities.

As we look forward to the upcoming school year, let’s carry the spirit of rest and renewal with us. A refreshed and revitalized team is key to continuing our mission of providing safe and efficient transportation for all students.

Thank you once again for your incredible work and dedication. Have a wonderful, restful, and enjoyable summer break!

Warmest regards,

Mike Sawyer | President

Legislative Report

To: CASTO State Board of Directors

From: David Neben

Memo: State Legislative and Budget Update

Dear President Thomas and CASTO Board of Directors,

The following memorandum contains informational updates on legislation and budget activities at the state Legislature. Please do not hesitate to contact myself or my staff with questions or concerns related to the material.

Thank you,

David Neben
CEO, Strategic Education Services

The Governor has published his 2023 Budget proposal. As of this quarter’s meeting of the State Board of Directors, we are still awaiting the publication of trailer bill language details to accompany the fiscal appropriations details.

Overall State of the Economy

The Governor’s Budget assumes the state is facing a significant decline in revenue growth over the next couple of fiscal years, beginning with the current year 2022-23. While this is not necessarily a recession, it means that some financial commitments from prior years will have to be either reduced or delayed in order to continue funding statutory ongoing programs like the Local Control Funding Formula (LCFF).

Electric School Bus Replacement

In discussions with senior staff from the Department of Finance, it was determined that the program to provide $1.5 billion for electric school bus replacement would remain uncut. Approximately $300 million in grant funding will still be available each year during the five-year allocation period.

Home-to-School Transportation

The 2022 Budget Act approved an increase in HTST funding up to 60% of a local educational agency’s costs of providing HTST services, according to SACS code function 3600. This equates to more than $600 million in additional ongoing funding for school transportation, and a total of $1.1 billion overall. The Department of Finance staff has indicated that this program will also remain untouched in determining where to find financial relief for the state budget.


The Legislature convened the 2023-24 legislative session on January 4, 2022, introducing a total of 40 new elected officials to the Assembly and Senate. The deadline for all legislators to introduce legislation for the first year of the session is February 17, 2023.

SB 88 (Skinner) – Pupil Transportation: School Pupil Activity Bus: Drivers

Senator Nancy Skinner has introduced SB 88. While the bill is still in “spot-bill” form and only contains legislative intent language, the general idea of the bill presents potential issues for school bus drivers and alleviating the current staffing crisis.

Action: We recommend CASTO maintain a neutral position on this bill until additional amendments have been published. | 855.227.8668
