## What this figure is, and what it is not

These are ADVERTISED figures: the pay an employer published in a job advertisement. They are not a survey, not self-declared pay, and not a record of what anyone was actually paid. Base pay only — no bonus, tips, overtime or equity. An employer may settle above or below the range it advertised.

## Method

Every London advertisement for Functional Assessor carrying an annual salary in the last 90 days is converted to a single currency; we report the 25th percentile, the median and the 75th percentile of that sample. Advertisements with no annual salary, and those quoting a day rate, are excluded rather than converted. Aggregated from public job listings on boards including Adzuna and Reed, recomputed nightly over a rolling window. A page is withdrawn — rather than frozen at a stale number — if fewer than 30 postings support it. Aggregate statistics only: no individual listing, employer name or advertisement text is published.

## Questions about this figure

### What does “advertised salary” mean?

It is the pay an employer published in the job advertisement itself. These figures are not a survey and not a record of what anyone was actually paid — they carry no bonus, overtime, tips or equity, and an employer may end up paying above or below the range it advertised.

### How is the Functional Assessor median in London calculated?

We take every London advertisement for Functional Assessor carrying an annual salary over the last 90 days, convert each to a single currency, and report the 25th percentile, the median and the 75th percentile. This cell currently reads £45,000 at the median, with a £39,554–£45,000 range.

### Why only 64 postings?

64 is the number of London advertisements that matched in the 90-day window — the real sample, stated rather than rounded up. We publish a figure only once at least 30 postings support it; below that the page is withdrawn rather than showing a number we cannot stand behind.

### Where does the data come from, and how often does it update?

Public job advertisements aggregated from boards including Adzuna and Reed, recomputed nightly over a rolling window. We publish aggregate statistics only — no individual listing, no employer name and no advertisement text appears on this site.
