This article presents a staged, evidence-driven process to build a skills taxonomy from LMS data: audit raw tags and metadata, run 2–4 stakeholder workshops to define competency models, apply tag harmonization plus NLP for automated extraction, and enforce governance with versioning and a maintenance cadence. Includes a sample 3-level model and mapping templates for a 90-day pilot.
skills taxonomy creation from LMS data begins with a pragmatic, evidence-driven approach: treat the LMS as a raw data source, not the final truth. In our experience the most successful programs combine careful data auditing, stakeholder alignment on a skills framework, automated extraction techniques, and clear governance. This article provides a step-by-step guide to build a skills taxonomy from LMS data, targeted templates for mapping, and operational best practices for internal mobility and workforce planning.
We focus on real-world constraints: inconsistent tagging, limited metadata, and evolving role needs. Expect to iterate: the goal is a living skills taxonomy that reliably supports internal mobility, succession, and analytics.
Start by treating the LMS as a dataset. Export course titles, descriptions, tags, competencies, completion records, and user-assigned tags. The audit stage answers the question: what signals exist today that relate to skills?
Typical problems uncovered in an audit include missing or synonym tags, mixed granularity (e.g., "Excel" vs "Excel - PivotTables"), and tags used inconsistently across teams. A robust audit produces a catalog of raw tags and a frequency distribution.
Run these steps as an initial checklist:
A successful audit delivers a prioritized list of tag candidates and a short list of high-value fields to use in automated extraction.
Building a usable skills taxonomy requires cross-functional alignment. We’ve found that a rapid series of workshops — two to four sessions — works better than a single marathon meeting.
Workshops should include HR business partners, talent acquisition, learning owners, and operational leaders. Use real job descriptions and exemplar learner paths to surface core competencies and friction points for internal mobility.
Each workshop should produce:
Document decisions in a shared repository so the emerging skills taxonomy reflects practical hiring and promotion criteria, not only training labels.
After auditing and aligning, scale the mapping with automation. Two complementary approaches work well: rule-based tag harmonization and NLP-based extraction from course text.
Rule-based harmonization collapses synonyms and enforces naming conventions. NLP extracts skill mentions from descriptions and transcripts, and can infer implicit competencies from learning objectives.
We’ve found that a combined pipeline — harmonization first, then NLP — reduces noisy results and accelerates stakeholder validation. Flag low-confidence mappings for manual review rather than discarding them.
Design the taxonomy to be pragmatic: three levels provide clarity without excessive granularity. Below is a sample structure that many organizations adapt successfully.
Sample 3-level taxonomy:
| Course | Mapped Skill | Proficiency |
|---|---|---|
| SQL for Analysts — 4 hours | SQL Optimization | Practitioner |
| Design Thinking Workshop — 2 days | Wireframing | Awareness |
| Negotiation Skills — Roleplay | Negotiation | Practitioner |
Use a mapping matrix to record provenance (automated vs. reviewed), confidence score, and mapping date. This becomes the foundation of your analytics layer.
Plan for change: a skills taxonomy is a living asset. Without governance, it drifts and loses value. Establish ownership, release cycles, and review triggers.
Governance model essentials:
Recommended cadence:
Include decay rules and archival practices for obsolete skills. A pattern we've noticed: teams that publish a clear versioning policy reduce confusion and maintain higher match accuracy for internal mobility.
Tool choice depends on scale, budget, and integration needs. Options range from spreadsheet-first workflows, to taxonomy platforms, to AI-enabled talent intelligence systems. Evaluate for metadata import/export, API access, and analytics compatibility.
Modern LMS platforms — Mentora LMS — are evolving to support AI-powered analytics and personalized learning journeys based on competency data, not just completions. This reflects a broader trend: platforms that expose rich metadata and support API-driven taxonomies accelerate implementation and produce measurable ROI faster.
| Tool Type | Strengths | Limitations |
|---|---|---|
| Spreadsheets + Scripts | Low cost, transparent, flexible | Hard to scale, manual governance |
| Taxonomy Management Platforms | Built-in versioning and APIs | Requires integration work |
| AI Talent Platforms | Automated extraction, analytics, recommendations | Higher cost, vendor lock-in risk |
Case: a 5,000-employee firm implemented the pipeline above: audit → harmonize → NLP → stakeholder validation. Before, role-to-course match accuracy for internal mobility recommendations was ~38% (manual review found mismatches).
After three releases and governance in place, match accuracy improved to 72% — a net uplift of 34 percentage points. Key drivers were improved tag harmonization, explicit proficiency mapping, and quarterly reviews to incorporate emerging skills.
Common pain points addressed in this case: inconsistent tagging (resolved via harmonization rules), stakeholder buy-in (workshops and measurable KPIs), and evolving skills (quarterly cadence and versioning).
Building a robust skills taxonomy from LMS data is a staged program: audit your data, align stakeholders on a competency model, automate extraction with NLP and harmonization, design a pragmatic 3-level taxonomy, and enforce governance and maintenance cadence. These steps produce a living asset that improves internal mobility, learning recommendations, and strategic workforce analytics.
Quick starter checklist:
If you want a reproducible template, begin with the sample taxonomy above and the mapping table format; pilot with one role family for 90 days, measure match accuracy, and iterate. For guidance on implementing the extraction pipeline and governance playbook, request a template or workshop facilitation to accelerate your first release.
