The core idea
Job evaluation assesses the relative demands of jobs within an organisation; market pricing examines external pay for comparable work. Armstrong and Taylor distinguish these complementary inputs to reward decisions. A pay structure groups jobs or pay ranges so decisions can be administered and explained. Evaluation concerns the job, not the popularity, negotiating skill or current performance of its holder.
Source and attribution [1]Using it in practice
Define the purpose and scope of the structure. Gather current job information and agree relevant factors or comparison methods. Train evaluators, record reasons and provide a review route. Compare suitable market data, taking account of role content, geography and benefits. Decide how progression will work and model the costs and employee impact before implementing changes.
An example, not a reported case
Worked example · illustrative
Two support roles have similar titles but very different responsibility for complex decisions. HR updates job information and evaluates demands before choosing market comparators. It then explains the pay ranges and progression rules. The team does not assume a market survey or historic salary proves the current arrangement is fair.
What to watch for
Both internal evaluation and market data can reflect bias or poor information. Equal pay is a legal matter with specific tests, not a guarantee created by adopting a grading system. Check current Acas and other authoritative guidance when assessing an actual issue.
Keep job and person decisions separate
A job’s grade reflects its assessed demands. An individual’s position within a range may reflect a separately defined progression policy. Explain the distinction and avoid quietly regrading a job to reward a favoured person.
Choose comparators carefully
Match actual work, scope and responsibility rather than job title alone. Examine sample quality and the date of the data. A median is the middle observation in an ordered distribution; it is not the arithmetic mean. Document which statistic is being used and why.
Review the system after implementation
Monitor anomalies, access to progression and unexplained differences. Update evaluations when work changes substantially. Give managers clear authority limits and keep exceptions visible so the structure does not erode through undocumented deals.
Take it into your next conversation
Three useful questions.
- Are we comparing jobs or judging people?
- How reliable are our external comparators?
- Can an employee understand and question the decision?
