Summary

Joseph Widmer Junior Elementary is a K-8 public school serving 923 students in Lathrop, California, as part of the Manteca Unified district, but it faces significant academic challenges with a current statewide ranking in the bottom 16th percentile.

Academically, the school performs below state and district averages, with only about 31% of students proficient in English and 18% in math; however, it does perform better than some nearby district schools like Golden West Elementary and French Camp Elementary. A notable concern is the dramatic performance gap when compared to local charter schools such as EPIC Academy and River Islands Technology Academy II, which achieve much higher proficiency rates despite similar or lower per-student spending.

The school has shown a historical decline in its state ranking and struggles with chronic absenteeism, though its rate of 23.7% is lower than several other Manteca Unified schools. Performance varies greatly by grade, with 5th-grade math proficiency being particularly low at under 6%, suggesting specific areas that may need targeted support, while the school has shown relative strength in supporting its English Language Learner students.
