Original Research by School Decision on Derfelt Herbert a Es
Derfelt Herbert A ES is a regular public elementary school in Las Vegas, Nevada, serving pre-kindergarten through fifth grade as part of the Clark County School District. It sits on South Lisa Lane in the 89117 zip code, a residential area on the west side of the city where housing values run above the statewide benchmark and rents are moderate by local standards. Home prices in the zip code have eased modestly over the past year, and rents have softened slightly as well, so a family moving into the area may find the rental market a bit more forgiving than the purchase market, where the estimated monthly mortgage outpaces typical rent by a meaningful margin.
The school serves a student body of roughly five hundred children across its grade span. Hispanic students form the largest group, with Black, White, Asian, and multiracial students also represented in meaningful numbers, giving the campus a genuinely mixed enrollment. Every student qualifies for free or reduced-price lunch, which is consistent with a school operating under a community eligibility or similar provision, and that tells parents the campus serves a population where economic need is widespread. Data on students with individualized education programs and English learners was not available in the records reviewed, so those who need specifics on special education services or language support would want to ask the school directly.
On state assessments, Derfelt participates in Nevada's SBAC testing in math and English language arts for grades three through eight, and a separate science assessment for fifth grade. Math proficiency landed at roughly a third of tested students scoring at or above grade level, and ELA proficiency reached a somewhat higher share, with both results reflecting room for growth. Science proficiency was lower still, with about a fifth of the fifth graders tested reaching proficiency. Participation was strong across all three subjects. Average scale scores were not reported for any subject, and no multi-year trend data was available, so a parent looking at whether results are improving or declining over time will not find that answer in the current data. A parent may want to look into the school's plans for strengthening instruction in math and science, where proficiency rates were the softest.
No data was available on staffing ratios, attendance patterns, disciplinary incidents, course offerings, or program features such as arts, music, or extracurriculars. The school's Title I status was also not reported, though the universal free-or-reduced-price lunch rate suggests the campus likely operates with federal support for high-poverty schools. Parents considering Derfelt should ask the front office about enrichment offerings, before- and after-school care, and any specialized programs the campus may run.
The district brief for Clark County School District searched for recent parent-relevant changes such as policy shifts, curriculum updates, bond referendums, or tax changes, but returned nothing tied to lasting family impact, so there is no district-level development to report here. Similarly, no locale brief was provided for the surrounding community, so the picture of the neighborhood is limited to the housing and economic data captured for the zip code.
What the assembled data describes is a standard neighborhood elementary school in a Las Vegas zip code where housing costs sit above the state median, serving an economically diverse but largely low-income student population with mixed academic results. ELA is the relative bright spot, math is middling, and science is the weakest area for which testing data exists. Families drawn to this part of Las Vegas for its west-side location and relatively accessible rents should pair a visit to the campus with direct questions about academic support, special education, and enrichment programming, since those pieces of the picture are not captured in the available records.
