A new argument in higher education calls for colleges to treat faculty investment as a core student-success lever rather than an optional cost line. The opinion piece argues that evidence consistently links instructional improvement—how instructors design, deliver, and support learning—to higher course pass rates, persistence, and completion. It criticizes institutions that respond to budget and scrutiny pressures by shifting investment toward technology and infrastructure while underfunding faculty professional development. The author describes typical shortcomings as fragmented, one-off workshops rather than sustained, evidence-based learning communities tied to student outcomes. In practice, the piece urges leadership teams to fund professional learning over time, explicitly connect it to institutional goals, and align teaching support with broader student success systems such as advising and redesigned math pathways.
