Summary

Centennial School is an alternative public school serving grades PK-12 in San Luis, Colorado, with a total enrollment of 186 students. While the school has maintained relatively high graduation rates and low dropout rates, it faces significant challenges in academic performance and chronic absenteeism.

Centennial School's four-year graduation rates have ranged from 80% to 84.2% in recent years, a notable achievement for an alternative school. However, the school's dropout rates have fluctuated between 0.9% and 3.8%, and its chronic absenteeism rates have been high, ranging from 27.7% to 53.5%. Academically, Centennial School's proficiency rates in English Language Arts (16.4%) and Math (18.2%) for all grades are less than half the state averages, indicating a significant need for improvement.

When compared to the nearby Sierra Grande K-12 School, another alternative public school, Centennial School demonstrates weaker academic performance across various standardized test metrics. This difference may be partly attributed to the fact that Centennial School serves a higher percentage of students eligible for free or reduced-price lunch (84.46% to 93.55%) compared to Sierra Grande K-12 School (81.79%), suggesting a more economically disadvantaged student population. Despite Centennial School's relatively low student-teacher ratio, which could be an advantage in providing individualized attention, the school's academic outcomes have not yet reached the level of its nearby counterpart.
