Education Path
Professors need a PhD (4-7 years beyond a bachelor's), often followed by postdoctoral research (1-4 years). The academic job market is extremely competitive, with hundreds of applicants per tenure-track position in many fields. Tenure review after 6 years evaluates research output, teaching, and service.
