What Is Actually in an Aptitude Assessment Report?

By Gabriele Herz · Executive Coach and Aptitude Assessment Specialist, Berlin

What is actually in an aptitude assessment report? And how can it be used to judge whether a person is right for a leadership position?

A CV shows a professional biography. An interview conveys a personal impression. For important personnel decisions, however, that is often not enough.

Because the decisive question is not only: What has this person achieved so far?

But: How well do their cross-functional competencies match the specific requirements of the future position?

This is exactly where professional aptitude assessment comes in. I would therefore like to give you a look behind the scenes of my work: What actually happens before, during and after an aptitude assessment interview, and how does a report emerge from it?

Before I ask the first question, I need to know: What competency requirements does the position have?

The starting point is not the person, but the position.

Before I can assess anyone, it must be clear what is actually required for success in the respective role. To that end, the relevant cross-functional aptitude characteristics are defined, along with the level of each that is required.

Depending on the requirements profile, my interviews examine up to six criteria from five possible areas:

Professional orientation: e.g. achievement, creative and leadership motivation
Work behavior: e.g. conscientiousness, flexibility and action orientation
Social competencies: e.g. sensitivity, assertiveness and team orientation
Psychological constitution: e.g. emotional stability and resilience
Leadership competence: e.g. goal orientation, reliability and self-reflection

The interviews are based on standardized aptitude assessment questions, drawn among others from the system of the Bochum Inventory of Job-Related Personality Description (BIP), which was developed specifically for the professional context.

The point is expressly not to judge a personality as "good" or "bad". It is about fit. A trait can be exactly right for one function, and too weak or even too strong for another position.

In the interview, the real detective work begins

Take the characteristic "resilience", for example.

The question "Are you resilient?" would yield little diagnostic value. Who would answer "No" to that in a selection interview?

So I am interested in something else:

How does someone recognize their own limits under strain?
Which situations are actually experienced as stressful?
How does the person behave under high pressure?
Which strategies do they use to cope with it?
And what have they learned from situations in which they reached their limits?

Exactly such aspects are reflected in the underlying rating scales. For each sub-area, they describe which behavior points to a low, medium or high level.

From many answers and concrete behavioral examples, a pattern gradually emerges. That is the difference between impression and assessment: observable behavior is classified against criteria defined in advance.

Research reviews on structured selection interviews have long shown that structure means far more than simply asking all candidates the same questions. The type of questions, the link to requirements and a systematic evaluation of the answers are part of it as well.

When the interview is over, the second part of my work begins

After the interview, the information gathered is evaluated, assigned to the characteristics examined and classified using the rating scales.

Then comes the decisive comparison: Which level does the person show, and which level does the position require?

In one report, for example, "action orientation" was examined. Among other things, this looked at how the person acts under time pressure, obtains information, weighs alternative courses of action, makes decisions and sets priorities.

An anonymized example from one of my reports shows how concrete such information can be: The candidate described a situation in which a critical IT security vulnerability created considerable time pressure. While "everyone is shouting over each other and has different ideas and interests", he described his own reaction as: "Sit down, talk it through." He took over the communication, analyzed the situation, discussed different options, involved those affected and prioritized the next steps.

The diagnostic assessment in the report read, among other things:

"The approach described appeared largely well thought through and comprehensible. Mr. ABC seemed to strike a balance between analyzing problems and implementing quickly."

No single answer decided the result. Only from the totality of the information was the level of the characteristic derived and then compared with the requirements profile of the position.

In simplified form, this results in the following chain:

Requirements profile → interview → concrete behavioral examples → rating scale → level → target-actual comparison → report

The report thus documents not only a result. It makes transparent how the assessment came about.

More is not automatically better

For me, this is one of the most interesting aspects of aptitude assessment. Many traits initially sound as if you could never have enough of them. Self-reflection? The more, the better. Assertiveness? Of course, as much as possible. Goal orientation? Likewise.

It is not that simple, though. A very high level of self-reflection, for example, can eventually lead someone to constantly question their own impact and become less action-oriented as a result.

A very high level of assertiveness can lead to pursuing one's own interests and positions forcefully even when more willingness to compromise or involving others would make sense. And a very strong goal orientation can tip into an overly aggressive approach, unrealistically tight planning or inflated expectations of others. A positive result therefore does not necessarily show up as the highest possible score.

The more important question is: How close is the actual level to the level that this specific position requires?

How reliable is such an assessment?

Can you really judge a person after an interview? Future professional success cannot be predicted with certainty. Aptitude assessment works with probabilities, not certainties.

But you can considerably improve the quality of the information on which personnel decisions are based.

In a classic job interview, sympathy, conversational dynamics and spontaneous impressions, or a "gut feeling", inevitably influence our perception. If candidates are also asked different questions, later decisions are partly based on information that is only comparable to a limited extent.

A structured aptitude assessment interview reduces exactly this problem.

The requirements are set in advance, relevant characteristics are examined systematically, statements are explored in depth using concrete behavioral examples and evaluated against defined criteria.

DIN 33430, the German standard for job-related aptitude assessment, therefore also looks beyond a single interview or test procedure. Quality arises across the entire assessment process: from requirements analysis through the selection and administration of suitable methods to evaluation, interpretation and documentation.

The goal is therefore not to predict a person mathematically.

The goal is to remove as much chance, subjective impression and avoidable misjudgment as possible from an important personnel decision.

What role does AI play here?

Personnel selection is also changing fundamentally right now. AI can make recruiting and selection processes faster and more efficient. For far-reaching personnel decisions in particular, however, I see its strength more in support than in replacing professional human judgment.

Because aptitude assessment does not consist only of assigning answers to a rating scale. In the interview, I ask follow-up questions, spot contradictions, connect different situations and try to understand why someone acted in a particular way.

The European AI Act, too, sets special requirements for certain AI systems in recruiting, personnel selection and promotion decisions and provides for human oversight.

People don't stand still

Aptitude assessment is "a business with people", and people change.

A leader gains experience. They take on new responsibility. They receive feedback. They may fail at a task and learn from it. They develop new strategies and change their behavior.

An aptitude assessment report is therefore not a label valid for life. It describes the levels observed at a particular point in time and with regard to a particular requirements profile.

For exactly this reason, it can be interesting for development and promotion decisions to repeat an assessment after, say, one or two years.

Then the question is no longer only: Where does this person stand today?

But also: What has changed since the last assessment?

This makes development progress visible, new development areas can be identified and, if the role has changed in the meantime, fit with a new requirements profile can be examined.

In the best case, a snapshot becomes a line of development.

What does a company do with the report afterwards?

Aptitude assessment interviews are suitable wherever decisions about staffing, development or fit have to be made, for example in:

Personnel selection
Promotion and succession decisions
Preparing training or coaching measures
Feedback and development decisions
Career and professional guidance

In a selection decision, the report can show where a person's profile matches the requirements of the position and where possible risks lie. In a development decision, a different question is often more interesting:

What can be developed from this?

And this is exactly where, for me, the circle closes between aptitude assessment and executive coaching.

Because assessment does not only show where a leader stands today. It can also make visible where development should focus.

Coaching then does not have to start from assumptions or a general self-assessment. A structured, documented basis for development is already in place.

And it remains after the coaching ends. Leaders can come back to it later, reflect new challenges against it and build further development steps on it.

The coaching ends. The basis for development remains.
