California's Best Competition 

The California’s Best event recognizes school bus technicians/mechanics for the important role they play in school transportation. The “Best of the Best Training and Competition” includes a written knowledge exam plus a “hands-on” competition to determine the “Best of the Best” in California.

The CASTO member Technician and Inspector with the highest score from a combined written and “hands-on” part of the competition will be sponsored by CASTO and will represent California at the National level. Once one is scheduled, the two winners will compete against other State winners from around the United States and Canada.


The competition is limited to the first 15 technicians and the first 15 inspectors to register.

CASTO will contact you to confirm registration in the competition.

All registrations are pending approval of the California’s Best Committee

You are not required to be CASTO members to compete, however ONLY the highest-scoring CASTO member will be sponsored by CASTO to compete at the National NAPT conference. If you are not currently a CASTO member, you can become a CASTO member by clicking here.

Technician Competitors, You will have 3 challenge stations. You will be given a maximum of 15 minutes for each station. All stations will be timed using a stopwatch. When you feel you have completed the task given at each station, you will need to call out “TIME” to the judge who will then record your time. Or the Judge will stop you at the 15-minute mark. Challenge station #1 time will be used if necessary in a tie-breaker situation. At the completion of the 3 challenge stations, you will take a 30 question written test with a 15-minute time limit.

Inspector Competitors 

You will have three test stations to complete.

Interior Exterior and Engine Compartment Undercarriage, Tires, and Wheels For each of the 3 test stations you will be given 15 minutes to complete. All stations will be timed using a stopwatch. When you complete the task given at each station, you will need to call out “TIME” to the judge who will then record your time. Or the judge will stop you at the 15-minute mark. The interior inspection time will be used, if necessary in a tie-breaker situation. During the inspections, the judge will write down all discrepancies you call out. Please be specific to the discrepancy defect and location. This is not an “Out of Service” criteria inspection. Everything is considered a discrepancy if it is not how the manufacturers built the bus new.

No part of the competition will require you to either start or move the bus.

Please let me know if you have any questions. I am here to assist you.  Kevin Sellstrom

The era of the “shade tree mechanic” in the school bus industry is over.  With the advent of computerized engines and transmissions and anti-lock braking systems, school bus mechanics can no longer rely on the “old school” of wrench-turning to get the job done.  With the arrival of the computer age, the years of the hammer and screwdriver repairs have disappeared.  Our field has changed more in the past five years than in the previous 20.  We now see diagnostics and diesel engine technologies that our fathers could not have foreseen.  To keep pace, it’s imperative that school districts and contractors expand training opportunities that encourage the development of their shop staff’s skills and knowledge base. 

The CASTO Mechanics Workshop provides an outstanding opportunity for mechanics to interact with each other while receiving quality technical training.

In addition to the Mechanic Workshop, CASTO is sponsoring the “CALIFORNIA’S BEST” completion in the Technician and Inspector categories. Mechanics can enter into either completion, the winner and CASTO member of each category will represent California at the National NAPT Conference.
