The basic objective of the study was to investigate the participation of mature adult women, over age 35, in the proprietary business, trade, and technical schools in Cuyahoga County, Ohio. Data were collected by telephone on the 29 registered resident-study schools of Cuyahoga County and two Cleveland-based home study schools pertaining to enrollment figures that reflect adult women's participation, the programs of study, and cost of attendance. Two institutions with more than 10 mature women enrolled were visited to obtain additional information regarding courses, facilities, and women's participation. The findings indicated that mature women over 35 years of age comprise about 2.5 percent of the total estimated enrollment of the 30 schools surveyed. Only one woman over age 35 was training for a nontraditional female job; two-thirds of the mature women enrollees were receiving training for clerical and sales occupations. The survey revealed that there are many openings available to mature women with the right skills and that proprietary schools are interested in providing such training; however, women re-entering the labor market often are unable to pay the training fees.
