Altimira Middle faces significant challenges compared to nearby schools. The school has a significantly higher percentage of Hispanic students (81.38%) and a higher percentage of students receiving free or reduced-price lunch (52.81%). Academically, Altimira Middle consistently performs below the district and state averages in English Language Arts and Mathematics, with only 27.18% of students proficient or better in ELA in 2022-2023, compared to 35.15% for the district and 46.66% for the state. The school also has a higher chronic absenteeism rate of 23.7%, compared to rates ranging from 15.9% to 36.5% in nearby schools. Additionally, Altimira Middle has a relatively high student-teacher ratio of 17.9, compared to the nearby schools, which range from 18.6 to 27.4.

The combination of Altimira Middle's low academic performance, high percentage of disadvantaged students, and attendance challenges suggests that the school may be facing equity issues that need to be addressed. For example, Adele Harrison Middle, which is in the same district, outperforms Altimira Middle in both ELA and Mathematics proficiency rates. Addressing these issues will likely require a comprehensive, data-driven approach focused on improving instructional practices, supporting student engagement and attendance, and ensuring equitable access to educational opportunities.

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.
