Original Research by School Decision on Landmark Elem School

Landmark Elementary School is a small public school in McHenry serving kindergarten through fifth grade, operated by McHenry CCSD 15. The school had a small enrollment. The student body was predominantly white, with a modest share of Hispanic students and very small numbers of students from other racial and ethnic backgrounds. Data on free-or-reduced-price lunch eligibility and special education or English learner populations were not available.

The school operated on a year-round continuous learning calendar, a scheduling model unique to McHenry County. That program has ended. In July 2024, the District 15 board voted to close Landmark at the end of the 2024-25 school year, and the school held its final day of instruction in June 2025. Students who attended Landmark are now assigned to their home schools for the 2025-26 school year and beyond. The district cited a substantial capital cost to modernize the building as a factor in the closure decision. The building has been sold and is being converted to a community center.

For families considering McHenry or this district, the relevant fact is that Landmark is no longer operating. The school's academic results from its final year are on record, but they are now historical. Third grade showed solid proficiency in math and passable proficiency in English language arts. Fourth and fifth grades showed weaker results, with about half the students meeting proficiency in math and substantially lower proficiency in language arts at fourth grade. Fifth grade proficiency in language arts was higher, and fifth grade science proficiency was in the mid-range. All students participated in state testing. The overall proficiency index across Landmark's tested grades and subjects placed it in the top quartile among districts in McHenry County, though year-round calendar programs and small schools sometimes operate with different teaching and assessment patterns than traditional schools.

Landmark's closure means the year-round school option is no longer available in the district. Parents seeking that calendar structure or a school-of-choice pathway in McHenry CCSD 15 will need to look at other districts or explore options elsewhere.

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.
