Summary
Jean Callison Elementary is a K–6 school in Vacaville, California, serving 762 students in Vacaville Unified. In 2025–26, 41% of students were proficient in English language arts (ELA), 27% in math, and 30% in science. The most important concern is that results were below California’s in all three subjects, with the largest shortfall in math: 12 percentage points below the state.
Science is the school’s strongest subject relative to comparison schools, while math is its weakest. Science proficiency was 30%, close to the nearby-school average of 31% and above the district’s 28%, though below the state’s 36%. Math was 27%, below the nearby average of 33%, the district’s 29%, and the state’s 38%; ELA was also below the nearby average of 45%, the district’s 46%, and the state’s 49%. Among the eleven schools compared, Jean Callison ranked sixth in ELA and science proficiency and seventh in math. ELA results improve in the upper grades: sixth-grade proficiency was 52%, above both the state’s 48% and the district’s 49%, while third-grade proficiency was 29%, well below the state’s 44%.
Results have weakened relative to the state since 2022–23: Jean Callison’s proficiency fell by 6 percentage points in ELA and 3 points each in math and science, while state rates rose in all three subjects. The school’s SchoolDigger standing also declined, from the 54th percentile in 2023–24 to the 39th percentile and 2 stars in 2025–26. Its 2024–25 student-teacher ratio was 23.7, above the nearby-school average of 22.7; 55% of students were free/reduced lunch eligible that year, close to the nearby average of 56%. SchoolDigger’s statewide ranking suggests notably stronger relative standing in how the school serves African American students: the school ranked at the 80th percentile in 2024–25, compared with its overall 46th percentile. Its Hispanic student ranking fell from the 72nd percentile in 2023–24 to the 43rd in 2025–26, while its overall ranking fell from the 54th to the 39th percentile.
