Original Research by School Decision on Harry D Jacobs High School
Harry D Jacobs High School is a comprehensive public high school in Algonquin, northwest of Chicago. The school draws from a growing suburban area where housing values and rents are rising modestly, and where families are moving into newly developed neighborhoods and subdivisions along the Randall Road corridor. The economic context is stable, with employment steady and median household income well above the national median.
The school enrolls students across grades nine through twelve, with a balanced class size across those grades and a total enrollment that is mid-range for a full secondary school. The student body is predominantly white, with a meaningful Hispanic enrollment making up roughly one-quarter of the school. Asian students, Black students, and students of two or more races each form smaller cohorts. State assessment data and graduation rates were not available for this report, so a parent or resident interested in academic performance measures would want to request that information directly from the school or district. Similarly, free-or-reduced-price-lunch eligibility data and counts of students receiving special education or learning English were not provided, so the school's economic and language-support profile cannot be characterized from the data at hand.
The school sits within Community Unit School District 300, which serves Algonquin and surrounding townships in McHenry County. The district recently undertook a significant boundary reassignment: in late 2025, the Board approved moving a portion of students who would otherwise attend Hampshire High into Jacobs High, starting in the 2026-27 school year. This change affects new residential neighborhoods south of Huntley Road, west of Randall Road, and north of Interstate 90, and reflects district projections of substantial enrollment growth over the coming decade. Parents buying homes in those zones should know their children will attend Jacobs, not Hampshire.
Beyond that immediate shift, the district faces longer-term facility pressures. The district completed a long-term master facility plan in 2024 and is considering placing a referendum on the November 2026 ballot to fund capital improvements tied to aging buildings and enrollment growth. The district's annual facilities maintenance budget covers routine upkeep, but a facilities referendum—whether it passes or fails—would have meaningful tax implications for the community and direct consequences for school conditions and capacity. Families in the district should follow that process as it unfolds.
Algonquin itself is a mixed suburban landscape. The historic Old Town district along the Fox River has undergone recent streetscape improvements and hosts a cultural center and locally owned retail, but most of the community is car-dependent. Schools and much of daily commerce are clustered along the Randall Road corridor, roughly a few miles from the downtown. The area is anchored by large employers including Motorola Solutions and Walgreens, as well as a major lifestyle retail center and newer commercial developments. Housing has appreciated steadily, and multiple large residential projects are underway or planned, including subdivisions of several hundred homes. Growth has brought traffic congestion and enrollment pressure on schools.
Jacobs High School will continue to absorb that growth as the district redirects students to balance capacity. Prospective families should confirm with the school or district what program offerings, extracurricular activities, and course pathways are available, as that detail was not in the data provided. For an academic profile, proficiency results, and graduation outcomes, direct outreach to the school is the clearest next step.
