The standout performer in this area is South Texas Independent School District (Isd) World Scholars, a magnet school that earns a 5-star rating and ranks in the 94th percentile statewide.

Among the traditional ECISD high schools, Robert R Vela High School is the strongest, earning a 3-star rating and improving from the 51st to the 61st percentile. It has the district's lowest dropout rate (0.9%) and highest graduation rate (94.3%). In contrast, Texasworks - Edinburg-Cte is the lowest-performing school, ranking in the 2nd percentile with critically low test scores and a high student-to-teacher ratio of 27.9:1. The other ECISD schools—Economedes High School, Edinburg North High School, and Edinburg High School—are clustered in the 21st to 61st percentile, indicating inconsistent outcomes across the district.
Key metrics show an average graduation rate of 90.2% and an average free/reduced lunch rate of 79.1%, reflecting high economic disadvantage. Spending per student varies from $8,389 at Premier High Schools - Edinburg Career & Technical to $14,195 at South Texas ISD World Scholars, but higher spending does not guarantee success—Robert R Vela outperforms Edinburg High despite similar funding. The charter schools, Premier and Texasworks, serve the most at-risk populations with high poverty rates and low test scores, functioning as alternative placements. Overall, the magnet school's exceptional performance demonstrates that high achievement is possible with the right structure, while the traditional high schools face challenges in achieving consistent quality across a high-poverty student body.
