Mayo Elementary, Compton CA - Test Scores & Data

Original Research by School Decision on Mayo Elementary

Mayo Elementary serves kindergarten through eighth grade in Compton, drawing students from a neighborhood anchored by residential and light industrial uses near downtown. The school enrolls a student body that is overwhelmingly Hispanic, with a substantial share qualifying for free or reduced-price lunch. Nearly all students live in or near the school's immediate area, reflecting the school's role as a neighborhood anchor.

On state assessments in math and English language arts, Mayo's proficiency rates sit above the midpoint when compared to other elementary and middle schools across Los Angeles County. In math, students showed proficiency ranging from around one-quarter in fourth grade to roughly two-thirds in sixth grade, with an overall rate of about one-half. In English language arts, proficiency was somewhat lower overall, centered around one-half, though sixth graders performed above that, reaching roughly three-fifths. Performance in fifth-grade science was substantially lower. The school has only one year of test data available, so trend patterns are not yet visible. Parents may want to ask the school directly about academic support strategies, particularly in science and in the fourth-grade math dip.

The school's grade structure reflects a transition point within the elementary band: kindergarten through fifth grade enrollment is distributed relatively evenly, while sixth through eighth grades show no enrollment. This suggests the school currently operates as a traditional elementary school in practice, despite its K-8 designation. Families should confirm directly with the school whether upper grades will be filled, remain unstaffed, or whether the configuration has changed.

Compton as a place is an urban city with mixed residential and industrial character, where walkability varies considerably by location. Downtown Compton functions as the civic and commercial center, anchored by a Civic Center completed in the 2010s with a public plaza and transit connections. The Metro A Line (light rail) serves the city with stations at Compton and Artesia, running roughly every fifteen minutes at peak. The city is pursuing growth through affordable multi-family housing, with recent projects including permanent supportive housing and smaller mid-rise affordability developments. Median household income remains below the level needed to afford newly constructed units without cost burden, a mismatch that shapes the housing market locally.

The district recently opened a new Compton High School campus for the 2025-26 school year, a major facilities investment funded by prior bond measures. In June 2026, voters approved Measure CPT, a bond measure to fund construction of a new Dominguez High School and other facilities, creating an ongoing property-tax obligation that families considering the area would weigh against state and local circumstances. The district also opened Compton Academy of Technology and Innovation, a P-TECH high school offering a tuition-free associate degree pathway alongside a high school diploma in fields such as biotechnology and cybersecurity, providing a distinct dual-enrollment option for students interested in career-focused pathways.

Data on chronic absenteeism, discipline, staffing, and English learner enrollment were not available for Mayo Elementary. The school's website information was not located. Parents interested in Mayo should reach out to the school directly to ask about curriculum, classroom size, support services, and the current status of upper-grade enrollment.

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.
