## 6 Findings--Analysis of Correlation between Career Characteristics and Competency Level
### Analysis of Correlation between Career Characteristics and Competency Level in Knowledge' Domain
#### 6.1.2 Analysis of the Designer Group
The specific competency item that showed a clear correlation with the 'BIM-based construction project experience' career characteristic proved to be 'BIM data quality evaluation'. In addition, 'Major functions of BIM software', 'LOD definition', 'Object and BIM library classification system', and 'Attribute value definition' competencies showed significant correlations with the said career characteristic. Specific competency items that showed significant correlations with the 'FAB-based construction project experience' career characteristic were 'CR certification criteria', 'Construction licensing standard', and 'Principles of CR'. In particular, a correlation was found between the 'FAB-based construction project experience' career characteristic and specific competency items related to the cleanroom, which is a characteristic space of FAB. \begin{table}
