Course by course and term by term, you teach college biology on contract — lecturing, running labs, grading, and guiding students, often while piecing together a living across more than one campus. College biology teaching, on contract.
The semester sets the rhythm: prepping lectures and labs, holding office hours, writing and grading exams, and fielding a steady stream of student email. Much of the real work is unpaid — prep and grading rarely fit the contact hours — and you're often teaching several sections to make it add up.
Job security tends to be the hard part. Contracts renew term to term, benefits are thin, and pay per course rarely reflects the credentials behind it. A community college, a big university, and an online program each bring different students and expectations, but the precarity is fairly common across them, and planning a stable life around it can be genuinely tough.
This path tends to suit people who love the classroom enough to weather the instability, often working scientists, retirees, or those building toward full-time teaching. If you need income that matches your degree, it can disappoint. But if lighting up a room of students about living systems is its own reward, the teaching itself can stay deeply satisfying.
