Dear ROWUSD Students, Families, and Staff,

As we geared up for the new school year, ROWUSD staff and leadership participated in a variety of trainings and professional development opportunities to ensure everyone was prepared to welcome and support our students.

These trainings help keep our team informed and aligned with District goals while strengthening practices in key areas, including student support, instructional practices, operational and safety preparedness, legal and compliance requirements, and meeting the needs of our diverse student population.

Ongoing professional development is an important part of our commitment to continuous growth and ensures our staff has the knowledge, tools, and resources needed to create safe, supportive, and engaging learning environments.

We are proud of the time and dedication our staff and leadership put into preparing for a successful school year and look forward to working together as partners with our families to help every student learn, grow, and succeed.

Page: Staff also had the privilege of hearing from guest speaker Garner Holt, who delivered an inspiring message about the importance of nurturing a child’s dreams and recognizing the potential within every student. He reminded us that a blank piece of paper can become a masterpiece and that what begins as a simple squiggly line may ultimately develop into something extraordinary. His message encouraged educators to look beyond what they see today, inspire creativity and curiosity, and recognize the possibilities within each child.
Page: As we begin this new school year, may we always remember to look beyond what is immediately in front of us and recognize the potential within every child. Every dream deserves encouragement, every idea deserves an opportunity, and every student deserves someone who believes in what they can become...!
