What are the two dimensions of Roe's occupational classification system?

Roe's occupational classification system is centered around two critical dimensions: fields and levels. The "fields" dimension categorizes occupations into broad areas based on the type of work and the environment, such as service, business, arts, and sciences. The "levels" dimension focuses on the complexity and responsibility required in various occupations, classifying them from semi-skilled positions to those that require advanced degrees and extensive training.

This dual-dimensional framework allows for a nuanced understanding of career options by aligning personal interests and abilities with suitable fields and levels of work. By structuring the occupational landscape in this way, Roe's model supports individuals in assessing their strengths and preferences against potential career paths, thereby facilitating more informed career choices and planning. This comprehensive approach highlights the interplay between the nature of an occupation and the level of expertise required, making it a foundational concept in career development theory.
