Summary

William Collier Elementary is a K-5 public school serving 707 students in Wildomar, California, within the Lake Elsinore Unified School District, an area where many families face economic challenges.

Academically, the school's test scores are below state averages, though it shows a relative strength in mathematics compared to other district schools. The school has made impressive progress in reducing the number of students who are chronically absent, cutting the rate significantly over the past few years. There are also notable improvements in outcomes for students in special education. However, performance in English Language Arts and Science remains an area for growth, and math scores tend to decline in the upper grades, which is a pattern the school is likely working to address.

When compared to nearby schools, Cottonwood Canyon Elementary in the same district performs higher academically, while Sycamore Academy of Science and Cultural Arts has a much lower chronic absenteeism rate. Schools in neighboring districts, like Cole Canyon Elementary in the Murrieta Valley Unified district, often achieve higher rankings, highlighting the varying performance across the region.
