Summary

Knightsen Elementary is a K-8 school serving 316 students in the Knightsen Elementary district, which is ranked in the top third of all districts in California.

The school presents a mixed academic picture: while its science scores are a clear strength, outperforming both the state and district averages, its English and math proficiency lags behind. Performance varies significantly by grade, with 8th graders doing well in English but 5th graders struggling notably in math. A key success story is a dramatic improvement in student attendance, with chronic absenteeism now lower than both the district and state averages. However, the school's overall statewide ranking has been inconsistent over the years.

Interesting comparisons emerge with nearby schools. Most notably, Old River Elementary, another school in the same district just a few miles away, achieves significantly higher test scores in English and math while spending considerably less per student. Compared to schools in other districts, Knightsen Elementary generally performs better than those in the lower-ranked Oakley Union Elementary district, like Oakley Elementary, but trails behind higher-performing schools in the Brentwood Union district, such as Isaac R. Montanez Elementary.
