How to Apply

Step 1 Determine if you are eligible

Eligible Applicants

  • All public school districts and open-enrollment charter schools in Texas.
  • Private schools do not qualify for funding.

Eligible Projects

  • Replacing pre-2007, diesel-fueled school buses with buses that are the current or previous model year at the time you apply. If a bus is used under a lease or lease-purchase agreement, it only qualifies as a retrofit project.

Vehicles eligible for replacement or retrofit must:

  • be powered by a diesel engine;
  • currently operate on a regular, daily route to and from a school during the regular school year—and for the two years immediately preceding the signature date on the application;
  • be in good operating condition, and, for retrofit projects, have at least five years of remaining useful life; and
  • have been owned, leased (retrofit only), or commercially financed, registered, and operated by the applicant in Texas for at least the two years immediately preceding the signature date on the application.
