Summary
Mireles Elementary is a mid-sized school in Corpus Christi, TX, serving 621 students in grades PK through 5 within the Corpus Christi Independent School District (Isd), and it has a history of strong academic performance, though recent years show a notable decline.
Mireles has a clear strength in 5th-grade mathematics, consistently posting proficiency rates between 58% and 64% over the last four years, which is significantly higher than both the district and state averages. In the most recent school year, its 63.64% proficiency rate was the second-highest among nearby schools, trailing only Faye Webb Elementary (70.53%). However, the school faces a challenge in 4th-grade math, where only 45.24% of students were proficient, a rate below both the district and state averages. This contrast suggests a potential instructional gap in the 4th-grade curriculum. Additionally, Mireles has a history of exceptional performance for its African American students, ranking in the 97th percentile statewide for this subgroup in 2021-2022 and maintaining high rankings in subsequent years.
Despite its strengths, Mireles has experienced a steady decline in its overall statewide ranking, dropping from the 90th percentile (5 stars) in 2018-2019 to the 66th percentile (3 stars) in 2025-2026. This decline is reflected across most subjects, such as 3rd-grade reading proficiency falling from 65% to 47.92% over the same period. The closest competitor, Creekside Elementary, located just 2.13 miles away, has a much lower poverty rate and has shown a strong upward trajectory, outperforming Mireles in nearly every subject and grade level. For example, in 4th-grade math, Creekside scored 72.84% proficient compared to Mireles' 45.24%. On a positive note, Mireles spends less per student ($9,606) than many nearby schools, such as Sanders Elementary ($12,320), while achieving better academic outcomes, indicating efficient resource use.
