Original Research by School Decision on Tammany High School
Tammany High School sits on Tammany Creek Road in Lewiston, a regional hub at the confluence of the Snake and Clearwater Rivers in north central Idaho. It operates as an alternative school within the Lewiston Independent District, serving grades nine through twelve. The enrollment is small, even for an alternative program, and the grade distribution tilts heavily toward the upper grades, with no ninth graders currently enrolled and the largest group in twelfth grade. The student body is predominantly white, with a smaller Hispanic presence and a few students identifying as American Indian or Alaska Native, Black, or multiracial. A substantial share of students qualify for free or reduced-price lunch. Data on special education and English learner enrollment was not reported.
The academic picture is thin, and what is available deserves careful reading. The state's assessment summary for this school carries no reported results, and the only academic trend data is an English language arts proficiency series showing several measurement points within the same school year, declining from a moderate level to a very low one. What that decline represents is unclear from the available data. It could reflect different cohorts, test windows, or the fluid enrollment that alternative schools often see, but the data does not say. No math, science, or other subject results were available. No graduation rate was reported. For an alternative school, a missing graduation rate may reflect the nature of the program rather than an omission, since alternative settings often serve students who arrive credit-deficient or are returning to school, and completion is measured differently. Still, a parent considering this school would want to ask directly about how the school measures progress, what its completion pathways look like, and what supports are in place.
Information on staffing, attendance, discipline, and course access was not reported either. Program offerings were not available. Civil rights data was not available. These gaps leave a family reliant on direct conversation with the school rather than published metrics.
Lewiston itself is a working regional center. Its economy rests on agriculture, paper and timber products, light manufacturing, and ammunition manufacturing, with Clearwater Paper as the largest manufacturing employer and CCI and Speer Bullet among the recognized industry names. Lewis-Clark State College brings a higher-education presence and civic identity to the city, including its ballpark hosting the NAIA World Series. The Port of Lewiston, Idaho's only seaport, anchors distribution and logistics. The city describes its economy as slowly diversifying, and it has identified development sites including a business and technology park, an airport business park, and waterfront land. A reservoir failure in recent years caused localized flooding, an event the city has absorbed. Public transit runs limited fixed bus routes with connections across the river to Clarkston, Washington.
For a family weighing housing costs, Lewiston sits below the state's typical home value but close to the national figure. Renting is considerably less expensive than carrying a mortgage at current rates, which may matter for families in transition or those who want flexibility while evaluating the school. The Lewiston Independent District's broader profile did not surface any recently reported strategic changes or initiatives of lasting impact, so there is little to relay on that front beyond the district's existing network of schools spread across the city's neighborhoods.
What Tammany offers is a small, alternative setting within a mid-sized Idaho city whose economy is steady if not fast-growing. The school's thin academic data and the unusual proficiency trajectory in the available ELA series mean a family cannot rely on published results alone to judge fit. The questions that matter here are practical: how the school serves students who need a nontraditional path, what completion and post-graduation options it connects to, and what day-to-day support looks like for a student body that includes a meaningful share facing economic need. Those are conversations to have with the school directly.
