Skills and Competencies Taxonomy (SCT) 2025: Standardized Occupational Descriptors

Version 1.0 of the Skills and Competencies Taxonomy (SCT) streamlines terminology for hundreds of occupational descriptors used in the Canadian labour market. Employment and Social Development Canada updated the taxonomy in 2025 to remove Oxford commas, correct syntax errors, and clarify labels and definitions. Significant changes were made to the Work Activities section, with twelve descriptors removed for overlapping and two relocated.

Use Cases

• Standardizing job descriptions and resumes based on the seven descriptor categories (skills, abilities, personal attributes, knowledge, interests, work context, work activities).
• Developing skills assessment frameworks based on the hierarchical sub-categories within the taxonomy.
• Building occupational information systems (like OaSIS) that require consistent measurement indicators across occupations.
• Analyzing labor market trends using the updated and clarified descriptor definitions from the 2025 version.

Strengths

• Provides a standardized framework covering hundreds of occupational descriptors.
• Organizes descriptors into seven distinct categories with further sub-categories for granularity.
• Updated in 2025 with specific revisions, including the removal of twelve overlapping descriptors and corrections to syntax and definitions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• Data may reflect geographic or institutional bias inherent to its Canadian government source.
