Data from the Mature Women's cohort of the National Longitudinal Surveys were used in an analysis of the acquisition of education and training by women at later ages over the 1979-89 period. These data described a sample of women who were between the ages of 30 and 45 in 1967 and who had been interviewed regularly at later intervals. Between the years of 1979 and 1989, the survey collected information about the occurrence and duration of all education and training programs. This analysis examined the extent of participation in education and training programs among this group of women from 1979-1989, a time in which they aged from 42-57 to 52-67. The time spent in education and training, as measured by total hours involved in these programs, was also analyzed. In addition, reasons why these women participated in programs outside of college education and company training over the 1984-89 period were addressed. Over 40 percent of women were found to have participated in some education or training program during the 11-year period. The primary forms of instruction were company training and college courses. White women more likely had some education or training than other women, but among program participants, other women spent more time in these programs than white women. Evidence on instructional programs other than company training and college education indicated that over one-third of the women participated in these programs for job-related reasons. (YLB)
