Methodology
How the self-assessment, judgment scenarios and knowledge check were designed, and the limits of each.
No figure without a source
Method & sources
How we form our judgments, where every figure comes from, and the limits of what we say. Every figure shown in the tool is registered with its source, type, confidence and review date.
Try it: where do our figures come from?
The evidence register now holds 127 registered claims. Pick a source type to see how many rest on it, with one example.
Official source
A record or statistic from an official body; it may be published or an internal administrative record (stated explicitly).
An example from the register
The two source workbooks end at the close of Q3 2026, and every national figure is read at that date.
International report or framework
A report or reference framework from an international organization or standards body.
An example from the register
SFIA 9, released in October 2024, contains 147 skills.
Survey
A result from a defined survey sample; it describes respondents, not everyone.
An example from the register
Employers expect 39% of workers’ existing skill sets to be transformed or become outdated between 2025 and 2030.
Self-reported data
A figure an organization publishes about itself or its platform; not independently verified.
An example from the register
In its 2025 report, Coursera reported 195% year-on-year growth in generative-AI course enrollments on its platform.
Editorial
A judgment or rule set by the tool’s author; declared and reviewable, not a measurement.
An example from the register
The public directory lists 587 active entities after cleaning: government, quasi-government, state-owned, nonprofit, international and sports bodies; no private and no abolished entities.
