Using a Cox Regression Model to Examine Voluntary Teacher Turnover

A Cox regression model was used to examine the career paths of 2,327 elementary teachers. The teachers were 1st-year teachers hired by a large Texas school district between August 1985 and November 1991. Five variables were investigated to determine their relationship with teacher survival: sex, age, ethnicity, education, and certification route (traditionally or alternatively certified). Little research has been done comparing attrition rates of alternatively and traditionally certified teachers. The methods used in the analysis are discussed as well as why these methods are more appropriate than traditional methods for examining teacher survival.
