Summary:

OCS - South is a public charter elementary school located in Altadena, California, serving grades K-8 with a total enrollment of 342 students.

OCS - South consistently outperforms the state average in Smarter Balanced Assessments for English Language Arts/Literacy and Mathematics across all grade levels.

While OCS - South's chronic absenteeism rate of 32.0% is lower than some of the nearby schools, such as Madison Elementary and Washington Elementary, it is still higher than the state average and could be an area for improvement. The school's diverse student population, with a mix of White (39.18%), Hispanic (33.92%), and Asian (8.77%) students, is a strength, and its relatively low student-teacher ratio of 20.1 is also noteworthy. However, the nearby private school, Paradise Canyon Elementary, has significantly higher academic performance than OCS - South across all subject areas.

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.
