Casis Elementary

Casis Elementary is a high-performing PK-5 school in Austin's 78703 area, serving 652 students as part of the Austin Independent School District (Isd).

Casis stands out for its exceptional math growth in upper grades. While 3rd-grade math scores are only slightly above the district average, 5th-grade math proficiency soars to 87.25%—a remarkable 35.83 percentage points above the district average. This upward trend is unique among nearby top schools like Highland Park Elementary and Gullett Elementary, which both show slight declines from 3rd to 5th grade. Casis also excels in 5th-grade science, with a 62.37% proficiency rate that nearly doubles that of Ridgetop Elementary (29.79%) and Mathews Elementary (38.3%). Reading is a consistent strength, though it is shared by several peers—for example, 4th-grade reading at Casis (79.31%) is lower than at Gullett (88.89%) and Maplewood Elementary (90.38%).

A notable concern is a recent decline in serving students from low socio-economic backgrounds. Historically ranking in the 91st percentile for this subgroup, Casis dropped to the 8th percentile in the most recent data—a stark contrast to its overall 92nd percentile ranking. This "equity paradox" warrants attention, as the school excels on average but may be struggling with its most vulnerable students. Per-student spending ($11,852) is higher than some nearby schools like Highland Park ($10,132) and Bryker Woods Elementary ($9,861), but lower than others like Maplewood ($12,708) and Reilly Elementary ($12,828). The student-teacher ratio (14.4) is mid-range, suggesting strong performance is driven by factors like parental involvement and effective teaching strategies.
