CORE Charter

Summary:

CORE Charter is an alternative public charter school located in Marysville, CA that serves grades K-12 with a diverse student population. The school has seen strong academic performance, with high graduation rates and test scores that outpace the state averages, particularly among its 11th grade students.

CORE Charter stands out for its impressive 4-year graduation rates, which have ranged from 91.1% to 93.6% over the past 3 years - significantly higher than the nearby alternative schools, which have graduation rates ranging from 26.7% to 81%. The school's students also outperform the state averages on Smarter Balanced Assessments and CAST Science tests across multiple grade levels. For example, in 2022-2023, 66.07% of 11th graders at CORE Charter were proficient or better in ELA, compared to the state average of 55.41%, and 53.57% were proficient or better in math, compared to 27.36% statewide.

While CORE Charter serves a relatively high percentage of economically disadvantaged students, with 50.11% qualifying for free or reduced-price lunch in 2022-2023, the school maintains a lower student-teacher ratio of 20.7 compared to many of the nearby alternative schools, which range from 9.5 to 26.6 students per teacher. This suggests that CORE Charter may be providing a higher-quality educational experience for its diverse student population compared to the other alternative options in the region, which tend to have higher rates of chronic absenteeism and lower test scores.

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.
