Correction

The original version of this article stated that full-time professors at Princeton earn $163,700 annually. In fact, full professors who have tenure earn that amount, while full-time faculty earn an average of $126,900 per year. The Daily Princetonian regrets the error.

Correction appended
The average full Princeton professor takes home $163,700 every year, according to an annual report by the American Association of University Professors' (AAUP). The University's overall national rank for professors' salaries fell from third to fourth this year.
Full professors at Rockefeller University, a biomedical science research institution in New York, are the nation's highest paid, earning on average $186,400 a year. Professors at Harvard came in second, with an average of $177,000, and Stanford overtook the University to rank third for the first time in six years, averaging $164,300 for full professors.
