Summary:

Robertson Charter School is an elementary school located in Decatur, Illinois, serving grades K-8 with a total enrollment of 329 students. The school is part of the Decatur School District 61, which is ranked 806 out of 813 school districts in Illinois and has a 0-star rating from SchoolDigger.

Robertson Charter School consistently ranks in the bottom 20% of Illinois elementary schools, with academic performance significantly below the state and district averages across all grade levels and subject areas. For example, in the 2023-2024 school year, only 26% of Robertson Charter School students were proficient or better in English Language Arts, compared to 41.2% statewide and 9.4% in the Decatur School District. The school also has consistently high chronic absenteeism rates, ranging from 37.4% to 59.4% over the past few years, and a high percentage of students from low-socioeconomic backgrounds, with 68.09% to 74.71% qualifying for free or reduced-price lunch. Despite spending significantly more per student ($14,838 to $17,927) compared to the state and district averages, the school's academic outcomes remain poor.

Interestingly, the nearby schools in the Decatur School District, such as South Shores Elementary, American Dreamer STEM Academy, and Muffley Elementary, also perform poorly compared to the state averages, but generally outperform Robertson Charter School in academic proficiency and other key metrics. Additionally, while Robertson Charter School's African American students perform relatively better than the school's overall performance, the school's female, male, and low-socioeconomic status students still perform poorly compared to their peers statewide.

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.
