Summary

Calla High is a small public high school serving 140 students in grades 9-12 within the Manteca Unified School District in Manteca, CA.

As an alternative education program, Calla High serves a student population with significant needs, which is reflected in its academic outcomes and state ranking, which places it in the bottom 15% of California high schools. The school faces a critical challenge with chronic absenteeism, with over half of students missing a substantial amount of school, a rate more than double the district average and far higher than nearby comprehensive schools like Sierra High (12.3%) and Ripon High (11.1%). While its graduation rate has improved to 81.4%, it remains below the district average of 92.7% and rates at schools such as Lathrop High and Manteca High.

Notably, Calla High receives significantly more funding per student and has a much lower student-to-teacher ratio than the surrounding comprehensive high schools, yet these resources have not translated into comparable academic proficiency. Its performance trends have been volatile, showing some strengths in supporting English Language Learners but indicating a need for program evaluation, especially when compared to other alternative options like Harvest High.
