Millersburg Area Middle School

Summary:

Millersburg Area Middle School is a public middle school serving 157 students in grades 6-8 in Millersburg, Pennsylvania. The school's academic performance has been mixed, with proficiency rates below the state and district averages in Math and English Language Arts, but better than the state average in Science. Millersburg's statewide ranking has fluctuated over the years, ranging from 277 out of 728 Pennsylvania middle schools in 2013-2014 to 499 out of 893 in 2022-2023.

Compared to nearby middle schools, Millersburg's performance is somewhat inconsistent. For example, Midd-West Middle School consistently outperforms Millersburg in Math and English Language Arts, while Camp Curtin Academy has much lower proficiency rates and a 0-star statewide ranking. Millersburg's high percentage of students (around 39%) receiving free or reduced-price lunch, a proxy for low socioeconomic status, may be a contributing factor to its academic challenges, as research has shown that students from low-income backgrounds often face additional obstacles.

Despite these challenges, Millersburg Area Middle School has maintained a 0% dropout rate, which is an impressive achievement. The school's spending per student has also increased over the years, from $14,876 in 2018-2019 to $16,488 in 2021-2022, suggesting the district is investing resources into the school. However, the academic performance has not seen a corresponding improvement, indicating that continued efforts to address the school's challenges and improve student outcomes will be crucial for its future success.

As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
