Principal's Message


May PostmaIt is with great pleasure that I welcome you to the Round Valley School website!

I am honored to serve as the new Principal of Round Valley School. RVS provides a positive, safe, and caring environment where all of our third, fourth and fifth grade students are challenged as they learn and grow. All members of our school community are committed to helping students thrive socially, emotionally, academically and physically.

Our students are provided with a program of study that includes balanced literacy, mathematics using real-life applications and the development of problem solving skills, next-generation science instruction and a robust social studies curriculum. Differentiation of instruction is used to tailor learning to the needs of individual students. A diverse Special Area program is also offered to enhance each student’s school experience.

The Responsive Classroom approach is utilized to help build our classroom communities. Our three school rules are, “Take Care of Yourself, Others and our Environment.” We have an amazing student body of respectful, motivated and enthusiastic learners.

I hope that you are able to take some time to explore our website. If you have any questions that you can not find addressed through your search, please contact us and we will be happy to assist you.
