Mariner Middle School

Summary:

Mariner Middle School is a public middle school located in Milton, Delaware, serving grades 6-8 with a total enrollment of 664 students. The school is part of the Cape Henlopen School District, which is ranked 2 out of 32 districts in Delaware and is rated 5 stars out of 5 by SchoolDigger.

Mariner Middle School has a relatively diverse student population, with 57.38% White, 12.65% African American, and 23.64% Hispanic students. The school consistently ranks in the top half of Delaware middle schools, with a 4-star rating from SchoolDigger. Its performance on Smarter Balanced Assessments and DeSSA tests is generally above the state average, particularly in English Language Arts. However, the school has experienced a significant increase in chronic absenteeism, rising from 16.2% in 2017-2018 to 26.3% in 2022-2023, which is a concerning trend.

Mariner Middle School's performance varies across different student subgroups, ranking highly for African American students but struggling with Hispanic students. Compared to nearby schools, Mariner's performance is generally stronger than that of Seaford and Woodbridge school districts, but it lags behind the high-performing Beacon Middle School, which is also in the Cape Henlopen district. The school's spending per student ($14,284 in 2018-2019) is higher than some nearby schools but lower than others, suggesting that its performance may not be solely driven by funding levels.

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.

Open Quote Mariner is a different school than it was years ago. The Admin staff have clearly made a difference. They have a wonderful active PTO. Teachers and staff are happy and it shows. The school looks great with positive saying posted all around the school. They encourage self respect by treating the students with self respect. The building itself feels comfortable and promotes a learning environment. My son in now in eighth grade. After spending all three years in Mariner Middle I can say I am completely happy with his whole experience. I am confident that he is ready for High School. I would recommend Mariner over Beacon anytime. Close Quote

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.
