San Diego Isd, TX - District Data

Original Research by School Decision on San Diego Isd

San Diego ISD is a small district of about 1,500 students across prekindergarten through grade twelve, serving a rural area in Duval County in South Texas. The district operates three schools: Collins-Parr Elementary, Bernarda Jaime Junior High, and San Diego High School.

The academic picture shows uneven performance across subjects and grades. In English language arts, the district achieves moderate proficiency in the elementary grades—around half of third and fifth graders meet or exceed standards—but proficiency drops somewhat in middle grades. Mathematics shows a similar pattern, with fourth and eighth graders performing solidly but sixth and seventh grade students struggling more noticeably. Science is an area of particular concern: only a small fraction of fifth graders meet the state standard, and while eighth graders fare better, proficiency remains well below the other tested subjects. Overall, the district's proficiency index places it at the top of Duval County's three districts, though the absolute numbers indicate room for improvement across the board.

The student body is overwhelmingly Hispanic, making up the vast majority of enrollment. Data on free-or-reduced-price lunch eligibility and English learner status were not available, so a parent may want to ask the district directly about socioeconomic composition and language support services. No graduation rate data was provided; this may reflect the most recent cohort's timing relative to reporting requirements.

Chronic absenteeism is notably high compared to other Duval County districts, at well above the county median. This is a pattern worth exploring with school leadership, as attendance directly affects student learning.

Per-pupil spending in San Diego ISD falls in the lower range among its county peers, a factor that may influence resource allocation and program breadth. The district does not appear to have undergone major bond measures, curriculum overhauls, or other significant operational changes in recent years that have been publicly confirmed.

Housing values in the communities served by the district—mainly San Diego and surrounding areas—are modest and have declined modestly in the past year. The median home value across the district's service area sits well below both state and national benchmarks, making this a relatively affordable market for families.

San Diego ISD is a small-town district with a tight-knit community profile, serving a predominantly Hispanic, Spanish-speaking population. It faces academic headwinds, particularly in science, and contends with attendance challenges that may merit close attention from parents considering enrollment.
