Aon Grid Challenge Test – Format, Practice & Scoring Tips

The Aon grid challenge test is a fast-paced attention and memory assessment used in pre-employment evaluations. This blog explains the test format, question types, timing, and how to improve your performance with free practice.

Also called the “scales sx” or “spatial challenge,” this test presents a dynamic grid where positions of shapes flash briefly. Your task is to recall and reproduce the sequence under strict time constraints. It assesses spatial memory, attention span, and working memory performance.

What Is the Aon Grid Challenge Test?

In each task, you’ll see a grid (usually 3×3 or 4×4) with cells that light up in a specific order. You must memorize the sequence and reproduce it. The number of items increases as you go, testing your ability to retain and recall visual patterns quickly.

• Test length: 5–8 minutes
• Each task shows a new sequence
• Time to view: 1–3 seconds per flash
• Response: Click or tap in the correct order

Common Mistakes to Avoid

This test feels simple at first but ramps up difficulty quickly. Many candidates make avoidable errors due to rushing or poor strategy. Here’s how to prepare better:

• Don’t focus too hard on the first flash — it’s usually easy
• Practice visual grouping to chunk positions
• Replay sequences mentally before responding
• Keep calm when making a mistake — it’s recoverable

Why This Test Matters to Employers

Companies use the grid challenge to assess attention control, visual processing speed, and working memory. These are key traits for roles in logistics, customer service, aviation, and data-heavy environments.
