Delta Charter Online has seen fluctuating graduation rates, ranging from 84.1% to 90.7% over the past few years, which is lower than the nearby Delta Charter school's 96.9% rate.

Compared to nearby alternative schools, Delta Charter Online has lower graduation rates and higher dropout rates than Delta Charter, but better metrics than some other virtual/independent study schools like Open Valley Independent Study and Tracy Independent Study Charter. The higher free/reduced lunch rate and student-teacher ratio at Delta Charter Online compared to Delta Charter indicate it may have more resource constraints and serve a lower-income student demographic. Overall, Delta Charter Online appears to be serving a more disadvantaged student population than some of the nearby traditional and charter schools, with lower graduation rates, higher dropout rates, and weaker academic performance, suggesting room for improvement in its virtual/independent study model.

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.
