Original Research by School Decision on Lyon Mack Ms
Lyon Mack MS is a regular public middle school serving grades six through eight in Overton, Nevada, a rural desert community in the Moapa Valley portion of Clark County. The school sits within the Clark County School District, despite its location far from the Las Vegas metro core that defines much of that district. Overton developed as the main business center of the lower Moapa Valley after the old town of St. Thomas was submerged by Lake Mead in the 1930s, and it retains a small-town character shaped by mining, agriculture, and proximity to Lake Mead and Valley of Fire State Park. Deposits of magnesite, kaolin, gypsum, and silica sand are actively produced nearby, and a gypsum plant on the southern edge of town anchors some local employment. The town is connected to Interstate 15 to the north and the Lake Mead National Recreation Area to the south by a state highway, and the surrounding landscape of mesas and foothills gives the area a remote, open feel.
The school's enrollment is modest for a middle school, with students distributed across the three grade levels. The student body is predominantly white, with a smaller Hispanic presence and very small numbers of American Indian or Alaska Native students and students of two or more races. Every student qualifies for free or reduced-price lunch, which reflects the economic profile of the surrounding community rather than any selective admissions criterion. Data on individualized education programs and English learner status was not reported, so those dimensions of the student population are gaps a parent may want to ask the school about directly.
On state assessments, Lyon Mack MS posts solid results for a school of its setting. In math, a majority of tested students reached proficiency on the SBAC, and in English language arts the proficiency rate ran slightly higher still. Science proficiency, measured at eighth grade, landed below the math and ELA marks but still represented a substantial portion of students meeting the state bar. Participation rates were strong across all three subjects. Average scale scores were not reported, and no multi-year trend data was available, so it is not possible to say whether performance is improving, holding steady, or slipping over time. A parent looking at these numbers would see a school where more than half the students are clearing the proficiency threshold in the core tested subjects, with ELA the relative bright spot and science the area where the most students fall short.
Because this is a middle school serving only grades six through eight, there is no graduation rate to report, and the state does not test below third grade, so those gaps are structural rather than missing data. The same applies to college and career readiness indicators, which are not part of the middle school profile. No course access, discipline, staffing, or attendance data was provided, and no programs or extracurricular offerings were listed, so a parent would need to contact the school to understand what electives, clubs, or support services are available beyond the tested core subjects.
The housing market in Overton is more affordable than both the Nevada state benchmark and the national benchmark, with typical home values sitting below those reference points. Rent data was not available for this location. The price-to-income ratio suggests that buying a home here is within reach for households earning near the national median income, and monthly ownership costs are lower than what many renters pay in higher-cost markets. The area has seen modest recent home value appreciation, while the broader state market has been softening. No information on recent housing developments or growth projects in Overton was found, and the community has remained small and stable, having merged with neighboring Logandale to form the unincorporated town of Moapa Valley. No parent-relevant district-level policy changes, curriculum shifts, or budget developments were identified for Clark County School District in the available research.
What a parent gets at Lyon Mack MS is a small rural middle school where the majority of students are reaching proficiency in math and reading, where the community is tight-knit and the cost of living is relatively low, and where the surrounding natural amenities, Lake Mead and Valley of Fire among them, shape daily life. The gaps in the data, around special populations, staffing, programs, and discipline, are real, and they mean a full picture of the school's environment requires direct outreach. What is visible in the numbers is a school performing above the midpoint in its tested subjects, serving an economically disadvantaged population in a quiet corner of Clark County.
