Mission and programs · 2025

Mission

Talent is equally distributed, but opportunity is not. STEM Advantage mentors, prepares, and inspires first-generation, low-income, and underserved college students for careers in science, technology, engineering, and math (STEM). We level the playing field by empowering talented students with access to networks, employment, and economic mobility often limited to students attending elite universities, while providing a vetted pipeline of skilled talent to businesses to fill their workforce needs.

  • Empowering the Next Generation of STEM Leaders. At STEM Advantage, we believe talent is equally distributed, but opportunity is not. We deliver a comprehensive, student-centered program designed to equip first-generation students with the skills, confidence, and connections needed to pursue and thrive in STEM careers. Our approach includes: Career Support: Targeted career programming that strengthens professional skills and builds confidence, empowering students to secure internships and entry-level positions in STEM fields. One-on-One Mentorship: Personalized mentorship from STEM professionals who serve as role models, offering guidance, support, and career coaching to help students navigate their academic and career journeys. Professional & Career Development: Interactive workshops, career panels, and industry events that prepare students for successful job searches, interviews, and career advancement. Scholarships: Financial support that enables students to attend classes full-time, get involved in a STEM-related club, and graduate with less student debt. Community and Networking: A robust support network that fosters a sense of belonging and provides students with opportunities to build connections with peers, alumni, and industry partners.We proudly serve students pursuing bachelor's degrees in STEM disciplines across California State University (CSU) campuses in Southern California, including the Greater Los Angeles region, Orange County, and San Diego. The CSU is the largest four-year public university system in the nationan incubator for untapped talent and ideal partner for driving impactful change at scale.Power of PartnershipsOur success is fueled by strong partnerships with leading companies and industry organizations. These partners not only provide funding and paid internships but also engage their employees as mentors, participate in career panels, and hire our graduates. Currently, STEM Advantage collaborates with over 50 companies, along with numerous professional and industry organizations, to create meaningful career pathways for our scholars.A Proven Track Record of Impact and Economic MobilitySince our founding in 2012, we have empowered over 1,000 Scholars with exceptional results: 100% have graduated with a bachelors degree in a STEM field. 72% are first-generation college students from low-income families. Scholars earn an average starting salary of $75,000a sustainable, middle-class living wage that represents a 400% increase over their average pre-program earnings. Scholars are projected to earn $2 million more in their lifetime post-programestablishing financial security, building wealth, and uplifting their families and communities.Our Scholars consistently describe the program as "life-changing and empowering," underscoring its ripple effectnot just on individual lives, but across communities. They are breaking cycles of poverty, achieving economic mobility, and becoming role models for future generations.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
