Abstract Placing Informaiton Technology staff in suitable job positions of employees, regarding their skills and knowledge is very important. However, percepting it as a difficult issue or inability in dealing with them leads to superficial, non-scientific and haphazard decisions within enterprises. The very important note in this matter is the large quantity and variety of indicators that affect the recruitment of IT staff, as well as the qualitative, vague and fuzzy nature of employment that makes it difficult to decide about selecting the righ professional. In this paper, after collecting the important criteria in evaluation of eight IT occupational groups, we define intervals for each of core skills in eight IT occupational groups by seeking experts opinions through Fuzzy Delphi technique.In the next step, we design a fuzzy expert system with Matlab fuzzy toolbox for IT personnel selection that its inputs are the score in each skill and the outputs are his/her grade in each IT occupational group. The findings of this research can be useful for managers in employeeing IT professionals and in their purposeful educational planning for IT occupational groups.

At the next step, we designed a fuzzy expert system with Matlab fuzzy toolbox for IT personnel selection that it's inputs are person's score in each skill and uotputs are his/her grade in each IT occupational group.
