Original Research by School Decision on Calero High
Calero High is a small alternative high school in San Jose's East Side serving grades ten through twelve. The school itself enrolls a small number of students, with the grades fairly evenly distributed across the junior and senior cohorts. The overwhelming majority of the student body is Hispanic, and a substantial share of students qualify for free or reduced-price lunch, reflecting a student population with significant economic need.
State assessment data for the school shows proficiency rates well below what would indicate grade-level mastery: English language arts results sit at a single-digit percentage, while math and science proficiency rates are near zero. These numbers are among the lowest in Santa Clara County. For context, Calero is an alternative school, a designation that typically indicates it serves students who have struggled in mainstream settings, including those returning from the justice system, those with chronic absenteeism, or those with other barriers to traditional education. Alternative schools nationally often show lower proficiency rates than district averages because of their population, not because the school is failing students; rather, the school exists to serve students for whom conventional schools have not worked. A parent should understand what Calero's specific mission is and whether it aligns with a student's needs. The proficiency data alone does not capture whether the school is helping students progress toward completion or moving them off a trajectory toward graduation.
State testing data on graduation rate, chronic absenteeism, and other student outcomes is not available in the records reviewed. For a grades 10-12 alternative school, a graduation rate or four-year cohort completion figure would be particularly relevant, and the absence of that metric makes it harder to assess whether the school is successfully moving students toward a diploma. A parent would benefit from asking the school directly about completion rates, credit recovery, and the pathways students follow after leaving Calero.
The school is part of East Side Union High School District, which covers San Jose and nearby areas. The district is managing significant headwinds. Enrollment has declined sharply over recent years and is projected to fall further. This has created a sustained budget deficit; in early 2026, the district voted to lay off more than eighty workers effective the following school year. In response to the financial pressure, voters approved a parcel tax in 2024 and a bond measure in 2022 to fund facility improvements and support career and technical programs, but ongoing staffing reductions suggest program offerings and class sizes could be affected. For a student at Calero, this context means the school is operating within a tightening fiscal environment that may limit electives, support services, or other enrichment.
San Jose itself is a mixed urban landscape. Downtown sits in the middle of a building boom, with tech companies and residential towers reshaping the center, and the city is patchwork of distinct neighborhoods ranging from dense walkable areas around downtown and neighborhoods like Willow Glen to sprawling residential suburbs in the east and south. Housing values and rents are high across the area. The broader economy is technology-focused, anchored by Cisco, Apple, Google, and other major tech employers, alongside traditional manufacturing and service sectors. The city has good public transit via light rail and bus, though many neighborhoods are car-dependent.
Calero High offers an academic pathway for students whose needs are not met in mainstream high schools. To assess whether it is the right fit for a particular student, a parent should investigate the school's completion and credential-completion rates, the specific student populations it serves and how it supports them, and what comes after graduation, whether that is a diploma, a high school equivalency, or a pathway to community college or employment.
