Original Research by School Decision on Green Mountain Elementary School
Green Mountain Elementary School is closed. The state directory lists its operational status as closed, and the most recent state testing data available is from the 2022-23 school year, which appears to have been its last year of operation. The school served elementary grades within the Jefferson County School District R-1 in Lakewood, Colorado, a large, predominantly suburban city immediately west of Denver.
Because the school is no longer operating, the academic picture comes only from that final year of testing. On the Colorado Measures of Academic Success, the share of students scoring proficient or above in math was low, with a much smaller portion reaching that bar than in English language arts. In ELA, roughly a third of students met the proficiency standard. In science at the fifth-grade level, the proficiency rate was also low. Participation rates on all three assessments were high, meaning the results reflect nearly all enrolled students in those tested grades. The school’s average scale scores in each subject placed it below the midpoint of performance across Colorado schools that year. A parent looking at these results should note that this is a snapshot of a school that has since closed—no trends are available, and no later data exists.
No enrollment information, demographic breakdown, or economic context for the school itself was available. The county and zip code data show that the Lakewood area in which the school was located had a housing market where typical home values were above the state median, and rental costs were also elevated. The area’s median household income was roughly in line with national figures, and the national unemployment rate at the time was modest. Lakewood itself has a mix of established residential neighborhoods, commercial corridors, and the Denver Federal Center, one of the largest concentrations of federal agencies outside Washington. The city’s growth has slowed after a mid-century boom, and recent development has focused on redevelopment projects like the Belmar mixed-use district.
The Jefferson County district has been through significant changes recently that are relevant to any family considering schools in the area. In late 2024, voters approved a bond measure for capital improvements, safety upgrades, and technology enhancements—the first such bond since a previous one more than a decade earlier. That same year, voters recalled three school board members in an election driven by concerns over transparency and the handling of school consolidation plans, replacing them with new members. The district had previously announced a plan to close 16 schools in 2023 due to declining enrollment and budget deficits but reversed that decision after community backlash. A committee was then formed to study enrollment trends and potential consolidation, with recommendations still pending. This ongoing process means that families considering other schools in the district should be aware that school closures and boundary changes remain a live possibility.
For a reader specifically looking at Green Mountain Elementary, the key takeaway is straightforward: the school no longer exists. The test results from its final year show a school where math and science proficiency were low and ELA proficiency was modest. The broader district context of consolidation planning and governance turnover helps explain why the school may have been closed, but the data provided does not detail the specific reasons for its closure. A family moving to the Lakewood area would need to look at other elementary schools within Jefferson County R-1 and investigate their current operational status, enrollment, and academic results directly.
