Summary:

The Clinton County R-III school district in Missouri comprises 3 schools: 1 elementary, 1 middle, and 1 high school. The data reveals that Plattsburg High stands out as the highest-performing school in the district, ranking 104 out of 367 Missouri high schools and earning a 4-star rating from SchoolDigger. Plattsburg High achieved a 100% four-year graduation rate and outperformed the state and district averages in Algebra I and Biology I end-of-course exams.

In contrast, Ellis Elementary and Clinton County R-III Middle appear to be struggling, with lower proficiency rates in Math and English Language Arts compared to state and district averages. The middle school had mixed performance, with some grades performing above the state average in English Language Arts and Science, but below the state average in Math.

The data also reveals variations in per-student spending and student-teacher ratios across the schools, suggesting potential inequities in resource allocation within the district. Additionally, the high percentage of free and reduced-price lunch recipients across all schools indicates a significant population of economically disadvantaged students, which may require additional resources and support to ensure their academic success.
