Summary:
Schools in ZIP code 86001 include six elementary schools, two high schools and one alternative school, serving elementary through high school students; enrollments range from 69 to 1,631, with 4,194 students total. Across schools, average all-grades proficiency is 47% in ELA and 37% in math, compared with state rates of 41% and 33%. The most important finding is that results vary widely by school: ELA spans 28% to 63%, while math spans 18% to 64%.
BASIS Flagstaff leads the reported all-grades results, with 63% ELA and 64% math—22 and 31 percentage points above state rates. Charles W Sechrist Elementary School is strong in both subjects, at 56% ELA and 55% math, respectively 15 and 22 points above state rates. At the other end, Lura Kinsey Elementary School has the lowest results in both: 28% ELA and 18% math, 13 and 15 points below state rates. Flagstaff Junior Academy shows why grade-level results can matter: its fourth-grade ELA is 64%, but its all-grades math is 21%, below the state’s 33%. Science also stands out at some schools: BASIS reports 89% in 11th grade, while Flagstaff High School reports 10%.
SchoolDigger’s statewide percentile rankings improved from 2023–24 to 2025–26 for Flagstaff Junior Academy (54 to 70), Flagstaff High School (44 to 53), Sechrist (69 to 75) and Eva Marshall Elementary School (31 to 33); these are rankings, not year-to-year test-score changes. Other distinctions may help families compare: Flagstaff High’s graduation rate is 95%, versus 80% statewide, despite mixed subject results, while student–teacher ratios range from 9.8 at Haven Montessori Charter School to 19.3 at Flagstaff High. Lower ratios do not consistently align with higher proficiency: Kinsey’s ratio is 12, yet its ELA and math results are the area’s lowest.
