Summer Institute Middle School

Our summer program, designed especially for grade 6-8 students, offers academics, arts, athletics and activities - and the flexibility to build a summer around your student’s interests.

Summer Institute Middle School

Morning and afternoon options allow students to focus on favorite academic subjects and sports activities.

Flexible options allow students to focus on one area – academics, arts, athletics or activities – or mix and match all four to create a wide range of summer experiences. The core two-week academic classes combine with arts, athletics and activities in a variety of ways, so students can build a summer filled with all the things they want to do.

Here’s what makes AP unique:

  • Limitless Options: From thrilling large- and small-group games to interactive contests, we’ve got something for everyone.
  • Weekly Themes: Each week brings fresh, themed workshops that inspire curiosity and creativity, from arts and crafts to sports skills, science, cooking and more.
  • Skill-Building Specialty Classes: Students dive deep into areas they’re passionate about, gaining a sense of accomplishment and learning new skills to take beyond the summer.
  • A Balance of Fun and Focus: Quiet library or study time ensures every student’s needs are met.

But it’s more than just fun, it’s growth! Our activities foster teamwork, leadership and self-confidence, encouraging students to collaborate toward shared goals and build resilience through individual challenges. Through active staff engagement, we model positive behaviors and empower students to shine.

What makes AP truly exceptional? It’s the magic of choice. Every day, students pick from activities designed to spark joy, laughter, imagination and curiosity. Whether they’re stretching their bodies with nontraditional physical games, exploring their creativity in hands-on workshops, or enjoying intellectual stimulation in quieter moments, every child finds a space to thrive.

Give your child the gift of a summer filled with discovery, connection and crazy, amazing fun. Enroll in our Afternoon Activities Program and watch them create memories they’ll treasure.
