High Schools in Rio Grande City Grulla Independent School District (Isd)

Summary:

The Rio Grande City Grulla Independent School District (Isd) in Texas is home to 3 high schools serving grades 9-12: Rio Grande City High School, Grulla High School, and Preparatory For Early College High School. This district serves a high-need student population, with all 3 schools reporting very high percentages of students receiving free or reduced-price lunch.

Among the 3 high schools, Preparatory For Early College High School stands out as the top performer, consistently ranking among the top 347-255 high schools in Texas over the past 3 school years and earning a 4-star rating from SchoolDigger. In contrast, Rio Grande City High School and Grulla High School have much lower statewide rankings, ranging from 1,446 to 1,609, and only receive 1-2 star ratings.

Despite the high poverty levels, all 3 schools maintain relatively high graduation rates of 97.7% and low dropout rates of 0.2% for the 2022-2023 school year. However, Preparatory For Early College High School significantly outperforms the other two schools and the overall Rio Grande City Grulla ISD district on STAAR End-of-Course (EOC) exams, suggesting the school may have effective practices or programs that could be replicated at the other high schools.
