Celebrating an Amazing Achievement! 🎉🎉🥳

We invite everyone to join us for light refreshments in the Professional Center (Room 1205) on Friday, March 13, 2026, as we celebrate Ms. Edith Ruiz for once again putting America’s Finest Charter School on the map!
On Saturday, March 7, 2026, CASTO Chapter 3 hosted the state’s first School Bus Safety Rodeo of the year.

Participants showcased their skills, learned from one another, and proudly represented the best of the transportation industry.

We are incredibly proud of Ms. Edith Ruiz, who earned 🥇 1st Place in the chapter with an outstanding score of 291 points! Her dedication and professionalism continue to bring great pride and recognition to our school and transportation team.

Feel free to stop by throughout the day to celebrate with us! You are also welcome to bring a dish to share with fellow staff members as we recognize this wonderful accomplishment.

👏 Congratulations, Ms. Edith!
