Programs described in its return (1)
  1. $232,057 spent. CORE is working to bring high quality education to rural Tanzania. We provide grants to Twegashe Integral Development (TID), a Tanzanian NGO, whose current major program is to construct and operate Twegashe Primary School in Bushasha Village, Tanzania. In January 2025, we welcomed 30 pre-kindergartners to Twegashe, bringing current enrolment to 208 students in grades pre-K through grade 5. In 2025, CORE continued construction of staff housing, having completed construction of all the school buildings in 2024. School facilities now include seven classrooms, cafeteria, kitchen, library, administrative offices, staffroom, and eight staff duplexes. CORE also continues to fund school operations and to build a scholarship reserve for Twegashe graduates. CORE is committed to high quality education. Our school program emphasizes community engagement, strong academics, and a focus on the whole child. Classroom instruction is in English so students will be successful in secondary school. We provide a nutritious breakfast and lunch for children, with fruits and vegetables from our school garden. We are committed to environmental sustainability. (continued on Schedule O) (Program service accomplishments continued) The school buildings and teacher homes are powered by solar energy, we use composting toilets, and we garden organically. Bushasha Village community engagement is high, with over 200 volunteers in 2025! In addition, there were 34 U.S. volunteers, including Michael Banobi and Jeannette Banobi, who spent more than eight months in the village volunteering and overseeing the entire project. U.S. volunteers also included 11 students from Lakeside School in Seattle who spent three weeks leading camp activities for Twegashe students through Lakeside's Global Service Learning Program. CORE's financial commitment to TID includes ensuring that CORE has enough in reserves to fully fund school operations for the current and following school year.
