Doctoral Scientists and Engineers in the United States
Achievement of tenure is directly corelated with years since doctorate. At 5 years or less since the Ph.D., only 6 percent had tenure. At 6 to 15 years since the doctorate, 47 percent had tenure. By the time 16 to 25 years had passed, 77 percent had tenure, and this proportion increased to 82 percent for those with more than 25 years since the doctorate (see Table 24 ).
Women with 5 years or less since the doctorate held tenure in higher proportions than men from the same cohort, 8 percent compared with 5 percent. After 5 years, however, the proportion of men with tenure was between 13 and 14 percent higher than for women in each cohort. As with faculty rank differences between men and women by cohort, the tenure rate differences may be partially explained by the tendency of women to have more gaps in their careers.
