STEM Diversity and Four-Year College Reform

 

Introduction

Higher education in the United States has become increasingly unaffordable, leaving behind millions of talented students — especially from underrepresented minority groups — who could thrive in science, technology, engineering, and math (STEM). The traditional bachelor’s degree structure requires about 120 credit hours (40 classes) spread across four years. With tuition, fees, and housing costs climbing every year, many students are either priced out or graduate with crushing debt.

This article proposes a bold solution: reforming the four-year degree into a two-year model with a streamlined curriculum, lower costs, and a stronger focus on career or graduate readiness.

Rethinking the Four-Year Model

American colleges have historically been built on a liberal arts foundation, where the first two years emphasize general education requirements — courses in the humanities, arts, and social sciences — before students specialize in their chosen field. While designed to cultivate broad critical thinking, this structure often burdens students with additional costs and time spent in classes unrelated to their career paths.

For STEM majors especially, courses such as philosophy, art appreciation, or physical education, while valuable in other contexts, do not always advance professional readiness. Instead, they add years and dollars to the degree.

A Two-Year Bachelor’s Model

A reimagined structure could include:

• One year of college composition (to build communication skills).

• One year of college math (to establish quantitative reasoning).

• All other courses focused strictly on the major and minor.

This would require about 96 credit hours (24 classes), delivered in a two-year program with three semesters per year at 16 credit hours each. By removing most electives outside of the major or minor, the degree becomes both faster and more affordable, while still preparing students for graduate school or the workforce.

Why This Matters for STEM Diversity

STEM fields remain crucial to economic growth and innovation, but diversity gaps persist:

• Black workers represented just 8% of STEM occupations in 2021, compared to 11% of the overall workforce (National Science Foundation, 2024).

• Hispanic workers made up 15% of STEM jobs, though their share of the total workforce was 18% (NSF, 2024).

• At the degree level, Asian students earn about 33% of their bachelor’s degrees in STEM, while Black, Hispanic, Pacific Islander, and Native American students cluster closer to 12–15% (NCES, 2022).

Cost is a major barrier. The average federal student loan debt is $39,075 per borrower (EducationData, 2025), and for public university graduates, debt at graduation averages $27,100 (APLU, 2024). In contrast, associate degree completers who borrowed carried a median of $14,166 in debt (Equity in Higher Education, 2023).

Research also shows that underrepresented minority students in STEM are more likely to drop out or earn lower GPAs than their White or Asian peers, even when entering with similar preparation (Whitcomb & Singh, 2020). Moreover, early academic success for Black and Latine students is less likely to translate into STEM enrollment compared to White students (NYU, 2023).

By reducing the cost and time required for a bachelor’s degree, a two-year model could remove financial barriers, increase completion rates, and open doors for millions of underrepresented students.

Benefits of a Streamlined Approach

1. Affordability: Fewer classes mean lower tuition, less debt, and more accessibility for low-income students.

2. Accessibility: A shorter pathway would allow millions more Americans — particularly minorities — to realistically pursue and finish a bachelor’s degree.

3. Relevance: Students focus on the knowledge and skills that directly prepare them for jobs or graduate programs.

4. Sustainability: Colleges could maintain or even increase enrollment, serving more students at a lower per-student cost.

Conclusion

The four-year liberal arts model was designed for a different era. Today, when the biggest barrier to equity in higher education is cost, it is time to rethink the system. A two-year bachelor’s degree — streamlined, affordable, and career-focused — could transform higher education, drive STEM diversity, and prepare students more efficiently for the future.

The path to greater representation in STEM does not only depend on better K–12 preparation; it also requires bold reforms in how we structure college itself. By removing unnecessary barriers, we can unlock innovation, opportunity, and equity for the next generation.
