Welcome to the 2025-26 school year in the Mark West Union School District! We anticipate a year filled with promise, purpose, and possibilities for our students.
We are a TK-8 grade school district with three elementary schools and a small charter middle school. If you are a returning family, thank you for once again entrusting us with your children. For those who are new to our district, welcome! You will find that our professional educators are committed to high standards of educational excellence and work hard to ensure that every student is challenged, supported, and inspired to reach their grade level expectations or higher.
While each school has its own unique culture, we all share in the value that safety is of utmost importance, both socially and emotionally. All sites have taken steps to ensure that our classrooms remain places where children can embrace a safe and secure learning environment. Just as importantly, we believe joy belongs at the heart of education, and we will work to create experiences that spark curiosity and a love of learning. Join us in partnership! As a caring and united community, we can make this year one where every child thrives.
