Sierra Grande K-12 School

Summary:

Sierra Grande K-12 School is an alternative public school located in Blanca, Colorado, serving grades PK-12 with a total enrollment of 289 students. The school is part of the Sierra Grande School District No. R-30, and its student population is predominantly Hispanic, making up 78.2% of the student body.

Sierra Grande K-12 School stands out for several key metrics. It has a very high percentage of students receiving free or reduced-price lunch, ranging from 77.51% to 87.36%, indicating a high level of economic disadvantage among the student population. The school also consistently underperforms the state average in various standardized test scores, including CMAS English Language Arts and CMAS Math, with proficiency rates significantly lower than the state averages. Additionally, the school has a relatively high student-teacher ratio, ranging from 14.8 to 11.6, which suggests a potentially higher workload for teachers and less individualized attention for students.

Comparing Sierra Grande K-12 School to the nearby Centennial School, another alternative public school, reveals some interesting differences. Centennial School has a lower percentage of free/reduced lunch recipients and a lower student-teacher ratio, but it also underperforms the state average in CMAS English Language Arts and Math, similar to Sierra Grande K-12 School. These findings suggest that Sierra Grande K-12 School may face significant challenges in providing a quality education, but the alternative school setting and the potential for targeted interventions and support could also present opportunities to address these issues and improve student outcomes.

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.
