Microbiological Sciences and Immunology at University of Puerto Rico-Mayaguez

UPR-Mayaguez's microbiology program starts graduates at just $22,932—well below the national median of $38,040—but the 43% earnings jump to nearly $33,000 by year four suggests meaningful career progression. Within Puerto Rico, this program actually performs at the 60th percentile, outpacing sister campuses like Arecibo by more than double, which matters if your child plans to stay in the local job market. The low debt load of $8,375 keeps the debt-to-earnings ratio manageable at 0.37, meaning graduates aren't drowning in payments while their careers build momentum.

The reality check: these are among the lowest earnings nationally for this degree, landing in just the 5th percentile. If your child is considering graduate school or mainland career opportunities, that national gap becomes significant. However, two-thirds of students here receive Pell grants, and the combination of minimal debt with steady earnings growth creates a viable path for students from lower-income families pursuing healthcare or research careers in Puerto Rico. The program works if staying local and avoiding crushing debt are priorities, but families expecting six-figure salaries within a few years need to recalibrate their expectations or consider how an advanced degree might change the trajectory.
