# What is Numerical Reasoning?

Numerical Reasoning is working accurately with quantitative information under time pressure — percentages, ratios, rates and multi-step word problems — choosing the right method before doing the arithmetic. It is a reasoning score rather than a maths qualification: the numbers are deliberately workable by hand, and what separates candidates is method selection, not calculation alone.

<!-- #levels -->
## What numerical reasoning looks like at four levels

- **Developing (0–39)** — Numbers slow you down right now; core operations need conscious effort and errors creep in under time pressure.
- **Emerging (40–59)** — You handle routine calculations but multi-step problems and time pressure still cost accuracy.
- **Strong (60–79)** — You work through quantitative problems accurately and at a good pace, with only occasional slips on the hardest items.
- **Exceptional (80–100)** — You process quantitative information rapidly and precisely, even on unfamiliar multi-step problems under time pressure.

<!-- #anti-signals -->
## Signs it is missing

- Produces a figure with no sanity check, so an answer an order of magnitude out reaches a customer or a board pack before anyone notices.
- Can operate the spreadsheet but cannot say which calculation the question needs, so the method is copied forward from last quarter's file.
- Adds successive percentage changes together, or applies a discount to the wrong base, and the error survives review because the arithmetic itself is correct.

<!-- #evidence -->
## Evidence to look for

- A pricing, margin or forecast line they produced: rerun one row of it with them and watch whether they check the result against a rough estimate before accepting it.
- A recurring report they own — ask what a single figure in it is derived from, and whether it would still be right if the denominator changed.
- A variance they explained to someone else: listen for whether the explanation names the base the percentage was taken against.

<!-- #develop -->
## How to develop it

- Drill mental-math fundamentals (percentages, fractions, ratios) 15 minutes daily for three weeks.
- Practise multi-step word problems untimed first, then reintroduce the clock only once accuracy is above 90%.
- After every practice set, rework each miss by hand and name the exact step where it went wrong.

## What measures numerical reasoning on AssessAll

- [Numerical Ability — Foundation](https://www.assessall.com/store/apt-numerical-foundation) — 25 items, about 20 minutes. Entry level, speed-weighted; reports Cognitive Speed as a second band
- [Numerical Reasoning — Graduate](https://www.assessall.com/store/apt-numerical-graduate) — 25 items, about 22 minutes. Graduate screening; speed-calibrated, so pace is part of the score
- [Numerical Reasoning — Professional](https://www.assessall.com/store/apt-numerical-professional) — 20 items, about 25 minutes. Power format — more time per item, method rewarded over pace
- [Complete Graduate Aptitude Battery](https://www.assessall.com/store/apt-battery-graduate) — 40 items, about 40 minutes. Five competencies in one sitting, reported as five bands

<!-- #confused-with -->
## Often confused with Data Interpretation

Numerical Reasoning is about choosing and executing the method; the arithmetic is the difficulty. Data Interpretation usually needs only simple arithmetic and the difficulty sits in locating the right cell and the right base. A candidate can be strong at one and weak at the other, which is why the battery forms report them as separate bands.
