Percentiles

In an environment where talent management demands precision and context, percentiles allow for the interpretation of results beyond absolute scores. It is not just about what a person achieves, but how they are positioned relative to others.

When we talk about percentiles, we are referring to a statistical measure that indicates the percentage of values that fall below a certain score within a distribution.

Why are they key in HR?

In Human Resources, percentiles allow us to contextualize results and make comparative decisions in a fairer and more objective way.

They are useful in:

  • Performance appraisals.
  • Talent identification and high-potential processes.
  • Psychometric assessments.
  • Compensation studies.
  • Climate and engagement analysis.
  • Internal and external benchmarking.

Let’s look at a clear example to understand it easily:

Imagine an organization where the average performance score is 8 out of 10. A person obtains an 8.2. At first glance, the result may seem high… However:

  • If that 8.2 corresponds to the 55th percentile, it means they are slightly above average.
  • If it corresponds to the 85th percentile, it implies they are part of the top 15% of performers.

The strategic difference is evident.

Example in compensation

In salary studies, percentiles are fundamental for defining compensation policies.

  • 25th percentile: lower market bracket.
  • 50th percentile: market median.
  • 75th percentile: competitive upper bracket.

If a company decides to position itself at the 75th percentile, it is opting for a salary strategy above the majority of the market.

What do they provide strategically?

Percentiles allow you to:

  • Identify differential talent.
  • Avoid decisions based on perceptions.
  • Establish objective criteria for promotion.
  • Design salary bands with real benchmarks.
  • Compare teams or areas using homogeneous metrics.
  • Detect internal inequalities.

Additionally, they foster more technical and less subjective conversations between managers and HR teams.

Percentile vs. percentage: what is the difference?

It is common to confuse both concepts:

  • Percentage: a proportional part of a total.
  • Percentile: relative position within an ordered group.

Scoring 90% on a test is not the same as being in the 90th percentile.

  • 90% is a score.
  • The 90th percentile indicates that only 10% obtained a higher result.

In People Analytics contexts

In advanced talent analysis models, percentiles allow for population segmentation, setting thresholds, and creating scalable decision criteria.

For example:

  • Top 10% for high-potential programs.
  • Percentile below 30 for specific development plans.
  • Year-on-year comparisons to measure real evolution.

In summary, percentiles help us turn data into context. They allow us to understand not just what score is achieved, but what that score means within the organization or the market.
