Summary:

The Seaford Union Free School District in New York is home to four high-performing schools, including two elementary schools (Seaford Harbor School and Seaford Manor School), one middle school (Seaford Middle School), and one high school (Seaford Senior High School). The district as a whole performs well above the state average on Regents exams and state assessments, with several standout schools that consistently deliver excellent academic outcomes.

Seaford Senior High School is a standout, consistently ranked among the top 25% of high schools in New York and earning a 4-star rating from SchoolDigger. The school boasts impressive test scores, with over 90% proficiency in Regents exams for Algebra II, English Language Arts, and U.S. History and Government, as well as a high graduation rate of 84.3% and a low dropout rate of 4.5%. Similarly, Seaford Manor School is ranked among the top 15% of elementary schools in New York, with exceptional performance on state assessments, including over 75% proficiency in English Language Arts and Math across all grade levels.

The district's strong academic performance is likely supported by its significant per-student funding, ranging from $30,281 to $35,755 across the schools. This level of resource allocation suggests the district's ability to provide quality educational resources and programs. However, the district should continue to monitor for any equity gaps and ensure that all students have access to the resources and support they need to thrive, as there are some disparities in test scores between the elementary schools.
