Used widely for roles requiring high attention to detail—such as admin, logistics, and finance—the Aon accuracy module (often referred to as “scales clr”) evaluates how well you can spot differences in numbers, codes, or text. Speed and precision both affect your final score.

What Is the Aon Checking Accuracy Test?

You’ll be presented with pairs or sets of alphanumeric strings (e.g., serial numbers, license plates, codes). Some are identical, while others contain subtle differences. Your task is to identify matches vs. mismatches accurately and quickly.

• Time limit: 6–8 minutes
• 30 to 50 comparisons total
• Click ‘same’ or ‘different’ for each
• Errors and delays both reduce score

Examples of What to Expect

Each item may include:

• Two license-like codes: e.g., ABT-4829 vs ABT-4892
• Part numbers or product SKUs
• Strings with 8–10 characters (some very similar)
• Visual clutter to challenge your focus

Top Tips for Aon Accuracy Test

• Use peripheral vision to scan faster
• Focus on groups (e.g., first 3 digits, then last)
• Don’t recheck every item – trust your eyes
• Stay calm if unsure – guessing incorrectly costs points
