Principal's Message

Julie Prestsater
Dear AEC Students and Families,
 
Welcome to the 2025–2026 school year! We’ve almost completed our first quarter and I’m so proud and excited for all that lies ahead. The start of the year has already shown what makes the Alternative Education Center such a special place — our students’ determination, our staff’s compassion, and our families’ partnership.
 
I want to challenge every student to keep showing up, staying focused, and doing your best each day. Whether you’re catching up on credits, exploring a new CTE pathway, or preparing for life after high school, every effort counts. The habits you build now will set the stage for your success this year and beyond.
 
As we look ahead, we remain focused on growth in all areas measured by the California Dashboard, including academics, graduation, and college and career readiness. This year, our goal is for every student to complete two dual enrollment courses and a full CTE pathway—equipping them with the knowledge, skills, and confidence to be college and career ready. By investing in our students today, we are building a stronger, more resilient community for generations to come.
 
Our Advance, Empower, and Connect goals guide everything we do:
 
     - Advance academic achievement through strong instruction and targeted support.
     - Empower students to take ownership of their learning and future through belonging, trust, and leadership.
     - Connect our school community through communication, compassion, and consistency.
 
Students at the AEC are fortunate to be part of a school that sees their potential and provides opportunities to start fresh and thrive. Here, every student is known, valued, and supported to reach their goals — no matter where their story began.
 
Thank you for making the first part of the school year such a positive start. Let’s keep that momentum going as we learn, grow, and succeed together.
 
With appreciation,
Mrs. Prestsater
Principal, Alternative Education Center
