Amphibious Achievement

The Issue

Over the past 50 years, the socioeconomic (SES) achievement gap has remained largely unchanged in the United States. The SES achievement gap between those in the top and bottom quartiles hovers around 0.8 standard deviations.

Like most urban school districts, the Boston Public School (BPS) system exemplifies the academic achievement gap. As of 2014, BPS students score 17% below the state average on the Massachusetts Comprehensive Assessment System (MCAS). Furthermore, average school graduation rates are 66% compared to state and national averages of 85% and 78%, respectively.

Many students who attend Boston public schools are traditionally disadvantaged. According to BPS data, 66% of its students are economically disadvantaged. One in three BPS students today is an English learner, and 75% are designated as “high-need.” To close the achievement gap, “high-need” students require additional support.

Achievement gap progress in Boston has plateaued in recent years. For example, a 2017 study found eighth-grade math scores had fallen by  3 points between 2012-2017, despite growth the previous 20 years. These students enter high school at an academic disadvantage and are unprepared to excel in higher-level classes. The pandemic worsened academic achievement, as BPS students lost 85% of a year of math education.

The stubborn endurance of academic achievement inequalities calls for new solutions. Despite limited progress, two approaches show promise: tutoring has been shown to improve cognitive skills and non-cognitive skills have been linked to educational benefits. Instruction inside and outside of the classroom is essential to promoting student growth.

However, few programs combine both approaches. Pathways out of poverty often depend on educational achievement — a high school diploma, bachelor’s degree, or speciality certification. Helping students meet their educational goals has a direct impact on their quality of life down the road. But, more evidence is needed to understand how innovative programs can support students in their education journey and improve their economic prospects later in life.

 

The Intervention

Amphibious Achievement is a mentorship program based at the Massachusetts Institute of Technology (MIT) that offers athletics and academics to BPS high school students.

Every Sunday, the high school students, known as Achievers, arrive on MIT’s campus and meet with their volunteer college mentors. The mentors provide two hours of athletics instruction in either swimming or rowing—sports which are inaccessible to most urban public school students. Then, the students have lunch together before beginning academic tutoring in small groups. Academic instruction can include homework help, college application advice, or a curiosity-driven STEM lesson.

The athletics portion draws participants who might otherwise steer clear of a tutoring program but who stand to benefit the most from the extra academic support. The program was founded by MIT student athletes who saw the benefits that athletics can have on academic and personal success. Amphibious Achievement’s goal, expressed by the tagline, is to promote student success in and out of the water.

 

Research Question

What is the effect of a low-cost enrichment program for disadvantaged high school students that combines mentorship, athletics instruction, and academic tutoring on secondary school achievement, post-secondary enrollment and completion, and adult financial outcomes?

Intended Outcomes

• Students who participate in the Amphibious Achievement program will have higher grade point averages in high school and higher rates of high school completion.
• Achievers will be more likely to enroll in college and graduate with a degree than non-Achievers. 
• Achievers will display improved financial well-being when they are in their late twenties.

 

Research Study Design

The Amphibious Achievement project is a retrospective, randomized evaluation.

Amphibious Achievement serves roughly 25 students a year; but most years, more than 25 students sign up for the program. Students are recruited to the program through information sessions at Boston public schools, referrals from teachers and school administrators, and by word-of-mouth. To deal with the oversubscription problem, Amphibious Achievement runs a lottery to randomly select students to participate. Randomization is the most fair way to determine admission when the program is oversubscribed.

In 2014, researchers at MIT ran a pilot study with 100 applicants at three Boston public schools. The study found that students who were randomly offered the opportunity to enroll in the program observed a 0.6 standard deviation increase in their GPA, moving from a C+ to B average. This increase is equivalent to a 60% reduction in the racial achievement gap.

LEO researchers are expanding the pilot study to analyze data from 2011 to 2025. An estimated 130 students from over 8 Boston Public Schools participated in Amphibious Achievement during this time period. Using data from Boston Public Schools, the National Student Clearinghouse, and Experian credit bureau records, LEO researchers will compare secondary-school achievement, post-secondary enrollment and completion, and financial well-being and distress outcomes between the control and treatment groups.
