Abstract This feasibility study is about setting up an assessment center in Chunghwa Telecom. The program is at the preliminary stage and thirty one assessors have been trained. The researcher asked those assessors to rank the importance of the forty core competencies identified for the target positions (section chiefs and center directors). Each assessor made the ranking twice: in theory (i.e., the ideal situation) and in practice. The template-matching technique was used to study the core competence fit between these two. The major empirical findings of the study are as follows: 1. There exists a general fit between the competencies for the ideal state and the practical state. 2. There are a few significant differences between the rankings for the two states. In nowadays, lower requirements for planning ability, judgment, training subordinates, and financial analysis, but higher requirements for persuasion, written ability, and body language. 3. There are age differences for the degree of fitness. 4. Those who have been certified as assessors have a stronger confidence in the assessment center.
