The simplest distinction is this: a behavioral profile helps us understand how someone is naturally inclined to approach their work; competencies tell us what someone has learned to do effectively.
Consider a company hiring a Sales Manager. The role might require someone who is comfortable taking the initiative, influencing others, working at a relatively fast pace, making decisions with incomplete information and challenging people when performance falls short. Those are behavioral demands. They describe the way someone may need to operate to navigate the environment successfully.
But none of those characteristics tells us whether the person can actually manage a sales team.
The competencies required for the same position might include coaching salespeople, conducting effective pipeline reviews, forecasting accurately, negotiating, managing performance, developing sales strategy and using a CRM effectively. These capabilities are developed through experience, training, feedback and practice. A candidate may possess the natural behavioral characteristics associated with the role and still have little evidence that they can perform these activities successfully.
That distinction sounds obvious when stated explicitly. In practice, organizations blur the two all the time.
An outgoing and persuasive candidate may appear to have the ingredients of a great salesperson, but being naturally social doesn't mean someone knows how to conduct discovery, qualify an opportunity, listen to a customer or manage a complex sales process. Equally, a quieter and more reserved individual may become an exceptional salesperson because they have developed outstanding questioning skills, industry expertise, discipline and the ability to build trusted relationships.
Behavior does not equal ability.
Behavioral assessments provide a different type of information from competency assessments. Rather than asking whether someone has mastered a particular skill, they help us understand the behavioral drives and tendencies that influence how that individual is likely to approach their work.
This can be enormously valuable when we understand what the job itself demands. Does the position require someone to operate with considerable independence, or will success depend on collaboration and consensus? Does the environment reward speed and comfort with ambiguity, or patience and consistency? Will the individual regularly need to challenge established thinking, influence skeptical stakeholders or operate within highly defined processes?
None of these behaviors is inherently better than another. Their value depends on the context of the job.
This is the principle behind tools such as the Predictive Index Job Assessment. Rather than looking for a universally "good" behavioral profile, organizations can define the behavioral demands of a specific role and then understand how naturally an individual's behavioral drives align with those demands.
The important word here is behavioral.
A PI Job Target is not a competency model, and treating it as one can lead to significant misinterpretation of the data. If a role requires relatively high Dominance, for example, that does not mean the role requires "strong leadership." It suggests that the environment may require greater independence, assertiveness and a willingness to influence outcomes. Leadership itself is far more complex and involves competencies that cannot be inferred from a single behavioral factor.
The same principle applies elsewhere. High A does not mean someone is a capable leader. High B does not mean someone is a skilled communicator. High C does not mean someone possesses empathy. High D does not automatically mean someone has developed strong attention-to-detail skills.
These characteristics may influence how someone approaches certain activities, but they should not be confused with evidence that the person can perform them effectively.
One of the easiest ways to see the distinction is to consider a phrase that appears in thousands of job descriptions: "strong communication skills."
At first glance, that sounds like a perfectly reasonable requirement. The problem is that it tells us remarkably little about the behavioral demands of the job.
What does strong communication actually mean in this particular role?
For a salesperson, it might mean confidently persuading a skeptical customer. For an engineering leader, it might mean translating complex technical information for a non-technical audience. For a people manager, it might mean listening patiently, creating psychological safety and delivering difficult feedback. For someone working in compliance, communication might mean producing precise, accurate documentation where clarity matters considerably more than charisma.
All of these people need "strong communication skills," yet the behavioral requirements associated with those activities may be very different.
This is why organizations need to resist the temptation to take a competency and immediately translate it into a behavioral characteristic. Saying that someone needs to be a strong communicator does not automatically mean they should be highly extraverted. Saying that someone needs to demonstrate leadership does not automatically mean they should be highly dominant.
The better question is: What does this competency need to look like in this particular job?
Once we understand that, we can begin to explore the behavioral demands associated with delivering it.
This also highlights a broader problem with the way organizations sometimes use assessments. There is an understandable desire to find a single source of data that tells us whether someone will succeed. Human performance simply isn't that simple.
A strong hiring process needs to consider several different dimensions.
First, there is behavioral fit: How is this person naturally inclined to approach the work, and how closely does that align with the behavioral demands of the environment?
Second, there are competencies: Can the individual demonstrate the capabilities required to perform the role effectively?
Third, there is knowledge and experience: Does the individual understand enough about the function, industry, technology, customers or regulatory environment to perform successfully?
There is also motivation and values. A person can have an apparently strong behavioral fit, excellent competencies and extensive experience, but still struggle if the work itself doesn't motivate them or if the organizational environment conflicts with what matters to them.
These dimensions should complement one another rather than compete with one another. Behavioral assessments can provide valuable insight into one part of the picture, while structured interviews, work samples, competency-based questions, references and evidence of previous performance provide information about others.
Perhaps the more important shift is in the question organizations ask.
Too often, hiring teams begin with the candidate: Does this person fit the profile?
A stronger process begins with the job: What does successful performance actually require?
That means understanding the outcomes the individual needs to produce, the competencies required to produce them, the behavioral environment in which they will be working and the natural behaviors that are likely to support success.
Only then should we compare the individual with the role.
This changes the role of behavioral data in hiring. Rather than becoming a simplistic pass-or-fail mechanism, it becomes a way of understanding alignment. Where will this person's natural behavioral drives support what the job asks of them? Where might they need to adapt? How significant is that behavioral stretch? And, importantly, do they have the competencies and experience that demonstrate they can perform the work regardless?
The goal isn't to find people who perfectly match a behavioral profile. The goal is to make better-informed decisions about people and work.
The distinction can ultimately be reduced to two questions:
Competencies help us answer: Can this person do the job?
Behavioral data helps us understand: How are they naturally wired to do it, and how much behavioral stretch might the job require?
Organizations that understand the difference are far better positioned to use both effectively.
