Original Research by School Decision on Floyd I. Marchus
Floyd I. Marchus is a special education school operated by the Contra Costa County Office of Education, located on Avon Avenue in Concord. It serves students from kindergarten through grade twelve, and every student enrolled is there because their individual education needs require a specialized setting. This is not a neighborhood school or a school of choice in the traditional sense; placement is driven by a student's Individualized Education Program.
The enrollment is very small, which is characteristic of schools like this. The student body is racially mixed, with white, Black, and Hispanic students each representing meaningful shares of enrollment. Roughly half of students qualify for free or reduced-price lunch. IEP and English learner data were not available in the data provided.
State assessment results exist but must be read carefully. California suppresses test scores when the group size is too small to report without risking student identification, and at a school this small, grade-level results are suppressed across the board for math, English language arts, and science. An aggregate proficiency figure is available, and when placed among districts in Contra Costa County, the school falls below the midpoint on the overall proficiency index. That figure, however, reflects a population selected specifically because of disabilities that affect academic performance, so a direct comparison to general education schools or districts does not give a useful picture of whether the school is serving its students well. A parent considering this placement would be better served asking the school directly about outcomes for students with comparable profiles and needs than relying on a county comparison that was not built for this context.
A graduation rate was not reported in the data.
The school sits in Concord, the largest city in central Contra Costa County and a city in active transition. Housing values in the zip code have declined modestly over the past year and remain well below the California state median, making the area more accessible than much of the Bay Area. Rents have ticked up slightly over the same period. Transit options are real: the city is served by two BART stations, with the Concord station connected by a short walk to the downtown core around Todos Santos Plaza. The plaza anchors a compact, pedestrian-oriented downtown with a weekly farmers market, dining, and summer programming. Beyond downtown, Concord is largely suburban in form, with an extensive park system and open space along Lime Ridge.
The city's biggest growth story is the long-delayed redevelopment of the former Concord Naval Weapons Station, a large site on the northeast side. A financial agreement with the Navy was approved in spring 2026, clearing the way for Brookfield Properties to build a large master-planned community there. City officials expect infrastructure work to begin around 2030 and first buildings to follow after that, so the near-term character of the city is unlikely to change quickly, but the longer arc points toward meaningful population and housing growth.
For families, the relevant questions here are not about AP offerings, dual enrollment, or graduation rate benchmarks. They are about what specialized support this school provides, how staff work with students whose disabilities require a non-traditional setting, and what the school's record looks like for students with needs similar to their child's. The data available here does not answer those questions fully, and a direct conversation with the school and with the placing district's special education team is the appropriate next step.
