John S. Martinez Sea and Sky STEM School

Summary:

John S. Martinez Sea and Sky STEM School is an elementary school serving grades PK-8 in the New Haven School District in Connecticut, with a student population of 476 that is predominantly Hispanic (90.13%).

Despite its STEM focus, the school consistently performs below state and district averages on standardized tests, with only 17% of 3rd graders and 15.4% of 7th graders proficient or better in English Language Arts, compared to state averages of 45.9% and 49.5%. In Mathematics, the school's proficiency rates ranged from 13.2% for 8th graders to 29.8% for 3rd graders, while the state averages were 51.3% and 38.2%. The school has consistently ranked in the bottom quartile of Connecticut elementary schools, with a ranking between 416 and 461 out of 490-538 schools over the past several years.

The nearby Celentano BioTech Health and Medical Magnet School and Wexler/Grant Community School also perform poorly on standardized tests and have low rankings, suggesting systemic challenges within the New Haven School District. The high percentage of students from low-income families and the school's high proportion of Hispanic and English Language Learner students may contribute to the school's academic challenges, and the school may need to implement targeted interventions and support to address the needs of these student populations.

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.
