Century Alt High

Summary:

Century Alt High is a public high school located in Los Lunas, New Mexico, serving grades 9-12 with a relatively small student population of 168 students. The school is part of the Los Lunas School District, which is ranked 87 out of 119 districts in the state and has a 1-star rating from SchoolDigger.

Over the past decade, Century Alt High has consistently ranked in the bottom quarter of New Mexico high schools, with its highest ranking being 132 out of 154 schools in 2009-2010. In the most recent school year (2023-2024), it ranked 153 out of 190 high schools, indicating it is one of the lower-performing high schools in the state. The school's four-year graduation rate has ranged from 22.4% to 76.7% over the past few years, which is significantly lower than the state average and the nearby high schools of Valencia High (76.7%) and Los Lunas High (76.7%). Additionally, Century Alt High students perform significantly below the state and district averages in both science and English language arts proficiency.

The high percentage of students from low-socioeconomic backgrounds at Century Alt High, with a 100% free and reduced-price lunch rate, likely contributes to the school's poor academic performance. This is significantly higher than the nearby high schools, which have free and reduced-price lunch rates ranging from 99.5% to 100%. While the school's challenges are significant, the data indicates that there may be opportunities for improvement, such as optimizing the student-teacher ratio, which has varied significantly over the years.

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.
