Harver NOA ability test: exclusion, analogies, number series
By the TestPrep editorial team · Updated
What to expect from Harver (NOA) examples
Harver is an online assessment platform used by employers to evaluate candidates. For the NOA Cognitive Ability Assessment, the most common question areas are analogies, exclusion, and number sequences.
This page gives concrete example situations so you can understand the format before you start. The exact assessment can vary by organization, but the underlying skills are usually similar: recognizing patterns, comparing information, and working accurately under time pressure.

This gives you an immediate feel for the question style and the value of the practice environment.
Typical example situations
In analogies, you may see a pair of words or concepts and need to identify the same relationship in another pair. For example, if one pair shows a category and an example, you look for another pair with the same link.
In exclusion, the task is to spot the item that does not belong. A practical example is a group of figures that share a feature such as shape, line type, or position, with one figure breaking that pattern.
In number sequences, you work through a series of numbers and look for a rule. Examples often involve simple arithmetic, but the pattern can also combine steps, such as alternating operations or changing differences.
How to approach practice in a clear way
- Start by identifying the question type so you know what to look for.
- Check the relationship or pattern before choosing an answer.
- Work through a few examples slowly, then gradually increase your pace.
- Review mistakes to see whether the issue was the rule, the comparison, or the time pressure.
This kind of preparation helps you become familiar with the structure of the assessment before the invitation arrives. That can make it easier to begin the real test without spending time figuring out the format.
When these examples are most useful
Example-based practice is especially helpful if you want to understand the style of the tasks before you take the assessment. It also helps when you know the test will be time-limited and want to get used to making quick, careful decisions.
Candidates who receive an invitation by email should check the message and the Harver platform for details. Since the exact setup can differ by employer, the safest approach is to prepare for the common modules and stay ready for the instructions you receive.
