Overview
Mission
To promote international friendship, peace, and cross-cultural understanding through educational programs, youth engagement, public diplomacy, and cultural exchange. The organization achieves its mission by developing afterschool enrichment programs, facilitating student-led global initiatives, hosting cultural festivals and civic receptions, and fostering people-to-people connections between San Diego and its sister cities, particularly Yokohama, Japan.
What it reported doing in 2024
Connect the World Afterschool Program ($155,717.83 expenses | $12,410 grant) Delivered Japanese language and cultural enrichment classes at Crown Point Junior Music Academy, Doyle Elementary, and partner campuses, serving over 75 students. Activities included bilingual instruction, intercultural projects, and virtual exchanges with sister schools in Yokohama. Covered payroll, classroom rentals, supplies, insurance, and digital subscriptions. The program builds global citizenship and youth leadership through cross-cultural learning.
Operating model
- Revenue model
- Earned-program. 88% of the money available for current operations came from fees and other program revenue.
- Distribution model
- Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
The verdict
STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Some filed totals do not add up and expenses are high relative to revenue.
