Only schools with a reported Biological Sciences earnings cohort in Puerto Rico appear. The figure reflects federally aided completers of Biological Sciences programs who were working and not enrolled four years after completing. It does not adjust for graduate school enrollment, cost of attendance, or the academic profile of entering students, and it is not a measure of teaching quality. The range and median below cover the 8 schools with a published figure. The spread from University of Puerto Rico-Mayaguez to University of Puerto Rico at Cayey is $14,558. ## Related rankings - Biological Sciences Colleges - [Best Colleges in Puerto Rico](/rankings/best-colleges-in-puerto-rico/) - [Best Biological Sciences Colleges in Texas](/rankings/best-biological-sciences-colleges-in-texas/) - [Best Biological Sciences Colleges in California](/rankings/best-biological-sciences-colleges-in-california/) - Biological Sciences Colleges in Alabama - Biological Sciences Colleges in Arkansas
