Aon scales clx: inductive logical reasoning test explained
Aon scales clx is Aon's "Inductive Logical Reasoning" test: you look at a group of items, work out the patterns and relationships between them, and use them to answer. Aon lists it as 6 minutes, so speed matters as much as insight. It is one of three Aon inductive tests, alongside scales cls and scales ix, and the same checklist works for all three.
- Official name: Inductive Logical Reasoning (scales clx).
- 6 minutes, according to Aon.
- Find common patterns and relationships across a group of items.
- Sister tests: cls (12 min, sort images into groups) and ix (5 min, odd one out of nine).
- Check shape → shading → count → position → rotation.

Quick summary
- Scales clx is Aon's 6-minute inductive logical reasoning test.
- You identify common patterns and relationships among items.
- It sits alongside scales cls and scales ix in Aon's inductive family.
- Check one visual feature at a time.
- Practise for speed: the rules repeat.
Aon's three inductive tests compared
| Test | Aon's description | Time |
|---|---|---|
| scales clx | Observe common patterns and interrelationships in a group of items | 6 min |
| scales cls | Understand the rules in the patterns, then assign new images to the right pattern | 12 min |
| scales ix | Understand the rules, then pick the item in a series of 9 that doesn't fit | 5 min |
A checklist for pattern items
- Shape: does a shape repeat, cycle or change?
- Shading or colour: fixed per row, alternating, cycling?
- Count: is a number of elements increasing or constant?
- Position: is something moving around the frame?
- Rotation: is something turning by a fixed angle?

Frequently asked questions
What is Aon scales clx?
Scales clx is Aon's 'Inductive Logical Reasoning' test. Aon says it measures your ability to look at a group of items and observe common patterns and relationships. Aon lists it as 6 minutes.
What's the difference between scales clx, cls and ix?
All three are Aon inductive tests. Scales clx (6 minutes) asks you to find patterns and relationships across a group of items. Scales cls (12 minutes) asks you to assign new images to the right pattern groups. Scales ix (5 minutes) asks you to find the one item in a series of nine that doesn't fit.
How do I solve Aon clx questions?
Check one feature at a time (shape, shading, count, position, rotation) across rows and columns, describe what the missing or odd item must look like, then check the options.
Is scales clx hard?
It's fast rather than hard: six minutes for a set of pattern items. The rules repeat, so practice makes a big difference to speed.
Does forge have Aon clx practice?
