Obsidian Middle

Summary:

Obsidian Middle School is a public middle school in Clearlake, California, serving grades 6-8 and part of the Konocti Unified School District. The school consistently underperforms compared to the district and state in academic metrics, ranking in the bottom 10% of California middle schools for several student subgroups.

Obsidian Middle's academic performance is a significant concern, with only 16.7% of students proficient or better in English Language Arts/Literacy and just 5.81% proficient or better in Mathematics, compared to 17.77% and 8.59% for the district, respectively. The school's struggles are not unique, as nearby schools like Terrace Middle and Middletown Middle also struggle to meet state averages. Factors like high rates of free and reduced-price lunch recipients and low student-teacher ratios at nearby schools suggest that socioeconomic challenges and resource allocation may be contributing to the poor academic outcomes in the region.

Obsidian Middle's performance has remained consistently poor over the years, with no significant improvement in its statewide ranking or test scores. This indicates that the school may be facing systemic challenges that have not been adequately addressed. Addressing these underlying factors could be crucial in improving educational outcomes for the students at Obsidian Middle and the broader community.

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.
