The Organization:
At Thrive Scholars, we provide high-achieving students from under-resourced communities the opportunities they need to thrive at top colleges and in meaningful careers.
Our comprehensive and data-driven program model focuses on the key inflection points that can be the difference between graduating from any college and graduating from a top college with the grades, degree, career skills, and network needed to thrive in any career. Thrive Scholars originated in Los Angeles as South Central Scholars ("SCS") twenty years ago. Over this time, the organization has refined its program model and, in the last five years, has focused on expanding nationally; reaching more high-achieving underrepresented students, growing the number of Scholars we serve; and deepening our program impact. Thrive Scholars has begun to grow its footprint with new summer program offerings in three additional cities, with more to come. The organization has approximately 75 year-round employees and close to 200 summer employees.
The Program: Summer Academy - Residential & Commuter:
Summer Academy has long been the keystone of Thrive Scholars' Six-Year Program, offering a signature summer experience through intensive college-preparatory courses taught by college instructors. Thrive's current strategic direction builds on the success of our residential Summer Academy to expand our impact by establishing commuter-based Academies in cities across the United States. We launched our first two commuter programs in Los Angeles and New York City in 2024 and Chicago in 2025, while simultaneously continuing to offer the residential Summer Academies for Scholars who do not have an academy in their community. We expect to continue extending our reach to other cities in the coming years.
The Students:
Our students are high-achieving, including first-generation college-goers from under-resourced communities, with an average high school GPA of 3.9 on a 4.0 scale. They are eager to learn, inquisitive, and highly motivated to succeed. In general, they see themselves as good students who perform well in school and are determined to live up to that expectation. When scholars attend their first summer academy, whether commuter or residential, they are a rising high school senior.
The Opportunity:
Thrive Scholars is seeking Teaching Assistants who can work with a faculty member to administer a college math or writing course to our students preparing for the rigor of courses at selective institutions. The math courses are expected to include Pre-Calculus, Calculus I, and Calculus 2. Final determination of math levels during the 2026 Summer Academies is to be determined based on student demand.
