Summary:

Guilford High School is a public high school in Rockford, Illinois, serving 2,071 students in grades 9-12. The school is part of the Rockford School District 205, which is ranked 737 out of 813 districts in Illinois and has a 0-star rating from SchoolDigger. Guilford High School has seen fluctuations in its statewide ranking over the past decade, ranging from 289 to 607 out of Illinois high schools, and has a current 2-star rating from SchoolDigger.

Guilford High School faces significant challenges in academic performance, with standardized test scores well below the state averages. For example, only 7.9% of 11th-grade students were proficient or better in SAT Mathematics, compared to the state average of 26.1%, and only 19.4% were proficient or better in SAT English Language Arts, compared to the state average of 31.1%. The school's graduation rate has also been lower than the state average, ranging from 72.2% to 76.8% in recent years, and its dropout rate has been higher, ranging from 6.3% to 9.5%. Additionally, Guilford High School has experienced a significant increase in chronic absenteeism, from 20.8% in 2019-2020 to 49.2% in 2023-2024, which is much higher than the state average.

While Guilford High School's performance is generally lower than the nearby Auburn High School and Rockford East High School within the same district, it outperforms the nearby Harlem High School, which is part of the Harlem UD 122 district. The school's challenges may be partly attributed to its relatively high percentage of students from low-socioeconomic backgrounds, with 52.49% of students receiving free or reduced-price lunch in the 2022-2023 school year.

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.
