Original Research by School Decision on Sinagua High School - Closed
Sinagua High School is closed. The school’s official status in the national directory is inactive, and it has not served students for many years. Any family looking at this profile will find that there is no current academic or enrollment data to review, for the straightforward reason that the school no longer exists.
When Sinagua High School was operating, it was a regular public school in Flagstaff, part of the Flagstaff Unified District. The grade band on record is “M through M,” indicating it served middle school grades, despite the “High School” in its name. The only assessment data available is from the 2009–10 school year, when Arizona administered the AIMS tests. For both seventh and eighth grade math and reading, the proficiency results were suppressed because the number of tested students was too small to report. A small number of eighth graders took those tests, but no reliable performance profile can be drawn from that year. Science results for eighth grade were also missing. In short, meaningful academic performance data for Sinagua High School was never publicly available in a usable form, and it certainly is not now.
Because the school is shut down, there is no enrollment count, no breakdown by race or ethnicity, no information on students receiving free or reduced-price meals, no data on special education or English learner populations, and no graduation rate. The civil rights, discipline, and staffing fields are all empty. There is nothing to compare with other schools in Coconino County, since the measure was not applicable.
The school was located in Flagstaff, a city situated at high elevation in northern Arizona, surrounded by the largest contiguous ponderosa pine forest in the country. Flagstaff’s historic downtown, centered on Heritage Square, features restored sandstone buildings from the late 1800s and early 1900s that now house shops, restaurants, and hotels. Northern Arizona University is a major presence, along with federal research installations like the U.S. Geological Survey and the U.S. Naval Observatory Flagstaff Station. Tourism drives much of the local economy, thanks to proximity to the Grand Canyon, Oak Creek Canyon, Arizona Snowbowl, and Historic Route 66. The city has also been a distribution hub, with employers such as Nestlé Purina PetCare.
For public schools in Flagstaff today, families look to the Flagstaff Unified District. The district operates several magnet and academy programs at the elementary, middle, and high school levels, including bilingual education, arts and science magnets, and technology and engineering academies. Dual-enrollment and career and technical education courses allow high school students to earn college credit and industry credentials while still enrolled. The district has sought voter approval for bonds and overrides in recent election cycles, which affects funding for facilities and programs.
The housing market in the Flagstaff area reflects its desirability as a place to live. Home values have typically run above the state and national medians, and rents are similarly elevated. The typical mortgage payment on a median-priced home would consume a substantial share of a median household income, making affordability a real consideration for many families.
For anyone researching Sinagua High School, the key takeaway is that it is no longer operating. There is no path to enroll there, and no past performance track record to consult. Families moving to Flagstaff should instead explore the current options within the Flagstaff Unified District, including its middle and high schools, to find a fit for their student. The school’s absence from the active roster means the data that would normally inform a decision simply does not exist.
