Best High Schools in Zip Code 83605

The three high schools serving ZIP code 83605 in Caldwell, Idaho—Caldwell Senior High School, Elevate Academy, and Canyon Springs High School—enroll students in grades 6 through 12 and serve a high-poverty area where chronic absenteeism and low math proficiency are major concerns compared with Idaho statewide averages.

Caldwell Senior High School is the academic standout among the three. It outperforms its own Caldwell District in both ELA (45.8% vs. 32.3%) and math (20.7% vs. 21.6%), and it has the lowest chronic absenteeism rate (26.3%) in the ZIP code. Even so, it remains well below state averages (53.9% ELA and 43.1% math) and has ranked in the bottom 20 percent of Idaho high schools for the past few years. Elevate Academy, part of Elevate Academy Inc., serves grades 6–12 and has the most alarming math numbers: just 6.4% proficiency, meaning fewer than 1 in 15 students is proficient, versus 43.1% statewide. Its science proficiency is relatively stronger, close to the state average. Canyon Springs High School has the smallest enrollment (169) and highest per-student spending ($9,214), but its 81.2% chronic absenteeism is nearly six times the state rate, and no recent test scores are reported.

For parents, the biggest takeaway is that attendance is the most urgent barrier in this area. Chronic absenteeism is 45.5% at Elevate Academy and 81.2% at Canyon Springs High School, while even the strongest school, Caldwell Senior High School, is nearly twice the state rate. All three schools serve high-poverty populations, with free/reduced-price lunch eligibility between 63% and 71%. Interestingly, the graduation rate is listed as 82.5% at every school, district, and the state, which may not tell the full story given such different attendance and achievement levels. Higher spending and smaller classes at Canyon Springs have not translated into measurable academic performance. In short, these schools need significant support in math and, above all, a sustained focus on getting students to school every day before academic gains can be expected.
