Extra Session is an optional after-school enrichment program for Agnes Irwin students in Grades PreK–4. Through constructive activities supervised by Agnes Irwin faculty and local instructors, students can learn new skills, exercise athletic abilities and discover their creativity. Classes are held Mondays through Thursdays from 3:30 to 4:30 p.m. and carry registration fees. Supervision is provided between the end of the school day and the beginning of Extra Session. During the 2014-2015 school year, students engaged in classes like Hands On Equations, Yoga, and Fairy Fun with Lower School faculty as well as classes led by local instructors: Walnut Street Theatre (Acting, Musical Theatre), Curious Jane (DIY Accessories, DIY Gifts), and Little Scholars (Cooking Around the World, Whiz Kids, Wood Creations, Green Thumb Club, World Travelers). A coding class, developed and led by Upper School students, was offered to second and third graders.
