Original Research by School Decision on Centennial Elementary School
Centennial Elementary School sits on Burrell Avenue in Lewiston, serving kindergarten through fifth grade as one of seven elementary schools in the Lewiston Independent District. It is a regular public school, and its enrollment places it in a moderate range for an elementary building in this region. The student body is predominantly white, with small representation from Hispanic, American Indian or Alaska Native, and multiracial students. About a third of students qualify for free or reduced-price lunch. Data on individualized education programs and English learner services was not reported, so families seeking that information would want to ask the school directly.
Lewiston itself is a regional hub at the confluence of the Snake and Clearwater Rivers. The city mixes industrial, commercial, residential, and educational uses, with Clearwater Paper's pulp and paper mill, ammunition manufacturers including CCI and Speer Bullet, and Lewis-Clark State College all contributing to the local economy. The Port of Lewiston, Idaho's only seaport, anchors distribution and logistics. Publicly reported community events such as the Dogwood Festival, Hot August Nights, and the Lewiston Roundup bring periodic street life, and the city operates two fixed transit routes with connections across the river to Clarkston, Washington. The terrain rises steeply from the downtown riverfront, which shapes how neighborhoods connect.
State assessment results from the most recent ISAT administration show a recognizable pattern at Centennial. In math, proficiency among third and fourth graders sits in a modest range, with just under half of tested students meeting the proficiency bar. By fifth grade, math proficiency rises to a stronger level, with about two-thirds of students reaching proficiency. English language arts follows a similar arc: third grade results are lower, with under a third of students proficient, but results climb through fourth grade and reach nearly three in five by fifth grade. Fifth grade science, the only grade tested in that subject, shows about half of students proficient. Average scale scores and participation rates were not reported in the available data. Trend data was limited, and the comparability of year-over-year changes could not be established, so it is difficult to say whether this grade-by-grade pattern reflects cohort growth, school effects, or other factors. What the results do show is that students tend to perform better as they move through the upper grades, particularly in math.
The housing market around Centennial reflects Lewiston's position as a mid-sized regional city. Typical home values in the school's zip code sit below the Idaho state benchmark and slightly above the national figure, with modest year-over-year appreciation. Rents are relatively low, and renting costs considerably less per month than carrying a mortgage at current rates, which may matter to families weighing near-term housing decisions. The broader economy has been described as slowly diversifying, with multiple development sites identified by the city including a business and technology park, airport business park, and waterfront land.
Centennial does not have graduation rate data because it serves only elementary grades, and that measure applies to secondary schools. The district brief for Lewiston Independent District did not surface any parent-relevant changes of lasting impact. We looked for information on staffing ratios, discipline data, course access, and attendance patterns, but these fields were not available in the provided data. Title I status was also not reported.
What a family finds at Centennial is a neighborhood elementary school in a working regional city, with assessment results that strengthen in the upper grades, a predominantly white student body, and a cost of living that runs below the state average. Families whose children would enter in kindergarten or first grade may want to look into the lower-grade proficiency results and ask the school about its early literacy and math support, since that is where the numbers sit lowest. The upward trajectory by fifth grade suggests the school builds student capability over time, and asking how staff approach that progression would help a parent understand what the pathway through Centennial looks like.
