Postma El, Cypress TX - Test Scores & Data

Original Research by School Decision on Postma El

Postma Elementary is a public school serving early grades in Cypress, an unincorporated suburban community about a short drive northwest of downtown Houston in the outer reaches of Harris County. The school enrolls a substantial student body across pre-K through fifth grade, with the majority of students qualifying for free or reduced-price lunch. The enrollment reflects the racial and ethnic diversity of the area: a significant share are Asian, with large shares of Black and Hispanic students and a meaningful White enrollment as well.

In state testing across math and reading for grades three and four, Postma's performance sits in the upper half among the districts across Harris County. In reading for third grade, proficiency stands at a moderate level, and fourth-grade reading performance is stronger. Math proficiency in third grade is lower and improves notably in fourth grade. The school shows broader strength across all performance tiers when looking at the full assessment picture: most students meet or exceed basic competency in both subjects. Science testing for fifth grade was not available in the data, so a parent may want to look into what science instruction looks like at the school directly. Data on graduation rates, attendance, and discipline are not applicable to an elementary school.

The school sits in Cypress-Fairbanks ISD, Texas's third-largest district, which operates across a rapidly growing region of master-planned residential communities and ongoing development. Housing in the Cypress 77433 zip code where the school is located is moderately priced for the Houston area and has remained relatively stable. The region has seen substantial residential growth over recent years, with many new neighborhoods, trail systems, and community amenities under development or planned. Parks, master-planned community facilities, and libraries anchor daily life rather than a traditional downtown, and the area is car-dependent.

At the district level, families should know about two recent shifts. The district reduced staff positions ahead of the current school year to address a budget shortfall, which included cutting campus librarians substantially, a change that affects library services across all schools including Postma. Additionally, curriculum and library materials have been a subject of board debate. In 2024 the board removed chapters from science and health textbooks covering topics such as climate change and vaccinations, then after a board election in November 2025, voted in early 2026 to restore those chapters. How materials are selected and challenged is something a parent may want to discuss with the school. On a positive note, the district lowered its property tax rate in 2025 to its lowest level in nearly four decades, reducing homeowner tax bills.

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.
