Summary:
The city of Plattsburg, Missouri is home to three schools: Ellis Elementary, Plattsburg High, and Clinton County R-III Middle. These schools serve students from pre-kindergarten through 12th grade and are part of the Clinton County R-III school district.
Plattsburg High stands out as the highest-performing school in the area, ranking 115 out of 378 Missouri high schools and achieving a 100% four-year graduation rate. The school also outperformed state and district averages on Algebra I and Biology I end-of-course exams. In contrast, Ellis Elementary struggled with test scores, with proficiency rates below state averages in most subjects and grade levels. Clinton County R-III Middle performed well on the 8th grade Science MAP test but had lower proficiency rates in Mathematics and English Language Arts compared to state averages.
Across all three schools, the chronic absenteeism rate was a concerning 11.0% for the 2023-2024 school year. Additionally, the schools had relatively high free/reduced lunch rates, ranging from 31.03% at Plattsburg High to 41.33% at Clinton County R-III Middle, suggesting that the Plattsburg area may face socioeconomic challenges that could impact student performance. Addressing the high chronic absenteeism rates and improving academic performance, especially in Mathematics and English Language Arts, should be priorities for the district.
