The student population is predominantly Hispanic (80.9%), with smaller percentages of Black (10.0%), White (3.7%), and Asian (1.5%) students. Economically disadvantaged students represent 97.1% of enrollment, significantly above typical district compositions. The district also serves 18.3% English learners and 11.5% students with disabilities.
Academically, the district's proficiency rates fall considerably below state averages. Math proficiency stands at 14.0% compared to Arizona's 32.4%, while reading proficiency is 19.0% against the state average of 40.2%. These gaps suggest substantial academic challenges in core subjects.
The graduation rate of 77.9% exceeds Arizona's state average of 67.3%, with a corresponding dropout rate of 4.5%. This indicates the district performs above state benchmarks in completion rates despite lower proficiency metrics.
Per-pupil spending is $15,524, slightly below the state average of $16,140.
