How long until someone gets tenure?
How long does it take to get tenure? Typically, a tenure-track professor works five or six years in a probationary period before that professor is up for the appointment. The tenure approval process can take months.
Why is it hard to get tenure?
Making tenure harder to get typically means that tenure-track faculty have to produce more scholarship, which is seen as evidence of higher quality faculty, gives an institution more apparent prestige, which makes it more competitive for getting students from a shrinking pool of applicants.
