THE OCCUPATIONAL SKILLS AND KNOWLEDGE INVENTORY (OSKI): A MEASURE VALIDATION STUDY ASSESSING PERSON-OCCUPATION FIT
With the changing nature of work, the strategic application of competencies such as skills and knowledge within the workforce is crucial to addressing the needs of the modern workplace. As such, governments, education institutions, and organizations are in consensus that there is a need for systematic assessments that measure these competencies. In line with these concerns, this study achieved two main goals. First, we adapted and validated a comprehensive skills and knowledge inventory that maps directly into O*NET skills and knowledge based on the Career One Stop Skills Matcher – a widely used skills inventory. Second, using three samples (including two longitudinal datasets), we provided validation evidence to support the measure’s adherence to statistical properties by examining validity evidence (concurrent and predictive). We found that convergence between corresponding skills and knowledge ratings with current and ideal careers coincided with higher reports of career outcomes such as career-choice satisfaction and demands-abilities fit (perceived fit) due to person-occupation fit. Also, the Occupational Skills and Knowledge Inventory (OSKI) examined reliability evidence explicitly focusing on profile reliability and rank-order stability (test-retest). We found that across profiles and samples, scores remained relatively consistent. These results are useful in advancing practical applications of skills and knowledge career exploration tools, as individuals and organizations can use them for career guidance. Overall, our measure provided essential validity and reliability evidence supporting its psychometric properties, which was a previous disadvantage of pre-existing skills and knowledge career exploration tools.
