Students Offering Support (SOS) is a multi-national charitable and entrepreneurial initiative that currently supports and develops individual SOS chapters within post-secondary institutions across North America. This organization's business model – uniquely designed "by students for students" – raises funds to build schools in Latin America through their Exam-AID review sessions, which are held prior to an exam and taught, as well as coordinated, by student volunteers. Model Students Offering Support (SOS) is a student-led charitable organization that currently supports and develops individual SOS chapters in post-secondary institutions across North America. The SOS model is “Raising Marks, Raising Money, Raising Roofs.” Each university SOS chapter's vision is to maximize charitable funds to raise roofs in rural communities within developing nations. The SOS mission is accomplished through raising grades during Exam-AID review sessions taught and coordinated by student volunteers for post-secondary students. With over 100 million children worldwide without access to education, Students Offering Support creates and implements sustainable education projects in developing nations with their annual outreach trips to Latin America. Raising Marks. Each university chapter of Students Offering Support conducts the Exam-AID program, which consists of 2-3 hour group review sessions held shortly before an exam. Exam-AID programs are taught by bright senior students who utilize SOS's unique teaching model to create an interactive learning environment. In addition to the review session, students are also provided with a take-home study guide to help them study for their approaching exams. Raising Money. The cost of an Exam-AID session is between $10 and $30, depending on the length and coverage of the session. Since its inception, Students Offering Support has tutored over 25,000 students in North America and raised over $700,000 for outreach initiatives in developing nations. For the 2011–2012 school year, the 26+ SOS chapters are working together to raise $350,000 for various sustainable education projects that will be implemented through their annual outreach trips to Latin America. Raising Roofs. All of SOS's projects are not only funded, but also personally built, by SOS volunteers during annual outreach trips. Student volunteers travel to a community in Latin America at their own expense, spending approximately two weeks building their designated project. SOS volunteers work very closely with a local NGO within each community to ensure that the projects and trips are properly organized, and even conduct follow-ups with the target communities in the aftermath of completing a project.
