The Riverdale Middle School has an ongoing relationship with Part of the Solution (POTS), a comprehensive service-agency for families in the Fordham section of the Bronx. Middle School students volunteer for a weekly trip to the POTS Family Club and the school organizes a springtime celebration for POTS Family Club families.
In 2018, the Middle School designated some of the proceeds from its annual dance-a-thon to the JE and ZB Butler Center for Children and Families at the Children's Hospital at Montefiore in the Bronx.
Some Middle School students also take part in service learning trips to New Orleans and Alabama. Every other year, students may apply to go on a community-service trip to Honolulu, Hawaii and Christchurch, New Zealand.
