In the third step, we returned to the DHOC to record the Holland environment codes that corresponded to the job titles.
3) Based on a sample of job titles, a cross-check with other sections of the DHOC, as well as the O*NET, suggested the failure to obtain matches for a number of job titles was not a result of our choice to use the DOT section of the DHOC For example, 'astronaut' is a PT job title that is not found in either the DOT section of the DHOC or in the O*NET.
In a similar manner, codes for occupations have also changed somewhat over the years in the three editions of the DHOC
It is assumed that information from this article may provide additional support for the usability and validity of the DHOC in career counseling.
The job title of fishing guide was located in the DHOC (Gottfredson & Holland, 1989) and a three-letter code of RES was identified.
It appears that both the DHOC and PCI hold promise as tools for understanding working-class occupations and for providing realistic occupational information on nonprofessional jobs to non-college-bound clients.
The job title of financial-aid counselor was located in the DHOC and a three-letter code of SEC was identified.
It could be argued that important similarities do indeed exist between the DHOC and the PCI.
In conclusion, it appears that both the DHOC and PCI hold promise as tools for understanding semi-professional occupations and for providing realistic occupational information on these types of occupations to college bound clients.
To determine the DHOC three-letter code that was most applicable to the nonprofessional occupation of the workers who participated in this study, a copy of the actual job description for this position was obtained from the manager of the company's personnel and human resource department.
The findings that there were no gender differences in PCI results and that there were high Iachan Index scores between the DHOC and the PCI reconfirm the generalizability of Holland's (1985) framework for classifying nonprofessional occupations as well as reinforcing the notion that the DHOC is a valuable source of occupational information for both men and women.
