Napa Valley Unified School District (NVUSD) students demonstrated notable academic progress on the Spring 2026 state assessments (CAASPP and CAST), highlighted by district-wide gains in mathematics and science proficiency. These preliminary results validate the effectiveness of NVUSD’s targeted instructional framework while providing valuable data as NVUSD continues to sharpen its ongoing professional development initiatives, including LETRS and High Impact Instructional Teams (HIIT).

District-wide science proficiency increased by over four percent, with 15 out of 26 school sites demonstrating measurable growth. Standout performance was led by elementary and middle schools, including double-digit gains at Pueblo Vista Elementary (+19.0%), Northwood Elementary (+14.6%), Napa Junction Elementary (+11.9%), American Canyon Middle School (+11.6%), Snow Elementary (+10.8%), American Canyon High School (+9.2%), Vintage High School (+9.2%), Napa High School (+5.6%), and McPherson Elementary (+4.8%).

Building on the previous year's gains, mathematics scores increased district-wide by nearly two percent, with 15 of 26 schools posting positive growth. Progress was observed across nearly all tested grade levels, highlighted by double-digit math growth at Pueblo Vista Elementary (+12.8%) and strong gains at Alta Heights Elementary (+9.3%), New Technology High School (+8.3%), Napa Junction Elementary (+6.5%), Browns Valley TK-8 (+5.2%), American Canyon Middle School (+5%), and Shearer TK-8 (+5%)

While some schools celebrated significant gains in English Language Arts (ELA) this year, such as New Technology High School (+10.3%) and Shearer TK-8 (+7.0%), overall district ELA scores experienced a minor decline of less than one percent. This follows a strong 2024–2025 school year where NVUSD posted a 4% increase in ELA proficiency, reinforcing the district’s ongoing commitment to keeping literacy a primary focus within its Strategic Plan and Board Annual Priorities.

"These early scores reflect steady, incremental growth in math and science, validating the hard work of our educators and the effectiveness of our instructional improvement efforts," shared NVUSD Superintendent Dr. Rosanna Mucetti. "At the same time, our preliminary ELA results show the importance of keeping literacy at the forefront of our work. Guided by our Strategic Plan and Board Annual Priorities, we remain dedicated to refining our practices, scaling what works, and ensuring every student receives the targeted support they need."

“Academic growth does not happen by accident,” shared Assistant Superintendent of Instructional Services Dr. Monica Ready. “It is built through the dedication of educators who believe in our students and support staff who ensure our schools thrive. I am deeply grateful to our entire NVUSD team for their unwavering commitment to our students' success.

To build on these results and accelerate student outcomes, NVUSD is implementing several key initiatives for the 2026–2027 academic year:

Leveraging DnA, a new centralized assessment platform, teacher teams will administer common end-of-unit assessments to gather real-time data and make timely instructional shifts.
Anchored in the Science of Reading and four completed LETRS coaching cohorts, NVUSD is embedding site-level literacy coaching across TK–12. The district is also integrating The Writing Revolution strategies across secondary science and history courses to deepen reading comprehension and text-based writing across all subjects.
Expanding on successful elementary models, secondary math educators will engage in professional learning focused on direct modeling to build student procedural fluency.
Utilizing the EduClimber platform, a platform that identifies areas where a student(s) might need additional support, site teams will analyze real-time data to streamline academic and behavioral interventions.

"As a Board member, it is important to see a data-driven approach guiding NVUSD’s work,” shared Board of Education President Dr, Lisa Chu. “I look forward to providing sound governance in my role as I support our Superintendent and staff in driving the academic progress essential to achieving Vision 2040."
