Anderson-shiro El, Anderson TX - Test Scores & Data

Original Research by School Decision on Anderson-shiro El

Anderson-Shiro Elementary serves prekindergarten through fifth grade in a small rural school district in Grimes County, Texas. The school enrolls roughly a half-thousand students, with roughly half qualifying for free or reduced-price lunch. The student body is predominantly white, with smaller shares of Hispanic, Black, and multiracial students.

The school sits in Anderson, a very small historic county-seat town centered on a courthouse square with antiques shops and cafes. The broader Grimes County region is experiencing growth as Houston's suburbs extend northward; new residential subdivisions with larger lots have appeared near Anderson in recent years, and the county's population has been rising. Anderson-Shiro CISD recently won a closely contested bond election to build a new elementary school and convert the current building into a junior high, with construction targeted for completion in mid-2027. This expansion reflects enrollment growth the district has seen since opening its secondary campus. The bond will increase property taxes for district homeowners.

State assessment data from 2025 shows a mixed academic picture. In reading, about two-thirds of third graders and roughly three-quarters of fourth and fifth graders reached proficiency. In math, third graders performed better, with a majority proficient, but fourth and fifth graders showed lower proficiency at just over half. Science proficiency in fifth grade was notably lower, with fewer than half of students proficient. The school reports that a majority of all students reached the "approaches" standard across subjects, and about a third met the highest "master" standard; reading performance overall outpaced math.

These grade-level variations suggest third graders are gaining traction in early reading and math, while upper elementary students encounter a steeper academic climb, particularly in math and science. Parents evaluating the school may want to ask what targeted supports are in place for fourth and fifth graders in these areas and what transition plans exist once the secondary campus opens. The school's formal designation as a regular public school and its lack of reported specialized programs means it offers a straightforward elementary pathway without alternative tracks or dual-credit options typical of larger districts.

Housing in the 77830 zip code centers on the historic district and surrounding properties where most residents own their homes, with median home values reflecting a rural Texas market. The school is not a Title I school and does not sit in a documented magnet or charter arrangement, so it draws its students through standard attendance zones in a consolidated rural district that spans both Anderson and the nearby community of Shiro.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
