THE APPOINTMENT AND TENURE OF 

 UNIVERSITY PROFESSORS^ 



The subject, appointment and tenure of 

 university professors, divides itself natur- 

 ally into two parts. With the question of 

 appointment wiU be considered also that 

 of promotion. The statements of fact 

 given below are confined to the twenty-two 

 universities which belong to this associa- 

 tion, viz. : California, Catholic, Chicago, 

 Clark, Columbia, Cornell, Harvard, Hop- 

 kins, Illinois, Indiana, Iowa, Kansas, 

 Michigan, Minnesota, Missouri, Nebraska, 

 Pennsylvania, Princeton, Stanford, Vir- 

 ginia, "Wisconsin and Yale. 



FACTS AS TO APPOINTMENTS AND PROMO- 

 TIONS 



The appointment and promotion of mem- 

 bers to professorial rank, with the excep- 

 tion of associate professors at Catholic 

 University, rest with the governing board. 

 Instructors and men of lower ranks are at 

 some institutions appointed by the senate, 

 faculty or president. Thus at Columbia 

 they are appointed by the faculty subject to 

 confirmation by the board, and such con- 

 firmation is purely formal. The governing 

 boards have different names in different 

 institutions. In the endowed institutions 

 the boards are usually called trustees; in 

 the state universities, regents; but neither 

 of these rules is invariable. At Harvard 

 and Yale the governing boards are called 

 corporations; at Missouri the governing 

 board is one of curators; at Iowa a board
