Employers, attorneys, hospitals, and public agencies routinely face situations involving concerning employee behavior. An employee may make alarming statements, act in ways that suggest psychiatric illness, or need to return to work following a mental health crisis. When these situations arise, understanding what question you need answered can determine whether you obtain information that is actually useful.

As a forensic psychiatrist who has conducted fitness-for-duty evaluations, served on disruptive behavior committees, performed violence risk assessments across criminal, civil, and occupational contexts, participated in workplace violence prevention efforts, and served as an Expert Reviewer for the Medical Board of California, one of the most common sources of confusion I encounter is the assumption that concerns about dangerousness and concerns about occupational functioning are the same issue. They are not, and the distinction has important consequences for organizations seeking guidance.

Should you obtain a fitness-for-duty evaluation or a threat assessment? The answer depends on the question you actually need answered, and confusing the two can leave you with an evaluation that does not address your real concern.

What Is the Difference Between a Fitness-for-Duty Evaluation and a Threat Assessment?

A threat assessment asks: How concerned should we be about the risk of future violence or other harmful behavior? It is designed to evaluate the likelihood of targeted violence, identify warning signs, and guide safety and risk-management decisions. Threat assessments are typically triggered by threatening statements, escalating or fixated behavior, or other conduct that raises direct concerns about workplace safety.

A fitness-for-duty evaluation asks: Can this individual safely and effectively perform the essential functions of the job? It is an occupational psychiatric assessment focused on the relationship between an identified condition and the functional demands of a position. Professional guidelines are clear that a psychiatric diagnosis alone does not determine fitness for duty.^[1][2] What matters is whether any impairment, whether psychiatric, cognitive, or substance-related, affects the employee's ability to perform their job safely and reliably.

These are distinct questions. Getting a threat assessment when you need a fitness-for-duty opinion, or vice versa, means you may walk away without the information you need to make a sound employment or safety decision.

When Both Questions Arise at Once

In practice, the two concerns often surface together. An employee exhibiting disruptive behavior, significant emotional instability, or signs of psychiatric decompensation may raise simultaneous questions about workplace safety and occupational functioning. This is particularly common in safety-sensitive fields such as healthcare, law enforcement, transportation, and public safety.

When both questions are present, a single comprehensive forensic psychiatric evaluation can often address them, provided both referral questions are clearly identified at the outset.

Consider three examples. A physician exhibiting disruptive workplace behavior may raise concerns regarding both patient safety and occupational functioning. A law enforcement officer experiencing significant psychiatric symptoms may present questions regarding both workplace safety and the ability to perform essential job duties. A physician referred for evaluation in a regulatory or licensing context may present questions regarding both fitness to practice and public safety.

In each case, the organization may seek an evaluation focused on one issue or a more comprehensive assessment addressing both. Either way, the evaluator needs to understand the referral questions before the evaluation begins.

Questions to Ask Before Making a Referral

Before contacting an evaluator, it helps to clarify your own concerns. Consider the following:

1. What specific behavior or incident prompted this referral?
2. Is my primary concern the safety of others, or the employee's ability to perform their job?
3. Is the employee in a safety-sensitive role where impaired functioning creates independent risk?
4. Have there been direct or indirect threats, or is the concern more about deteriorating functioning?
5. Do I need an opinion that will inform an employment decision, a safety plan, or both?
6. Have I clearly communicated all of my concerns to the evaluator before the evaluation begins?
7. Are there any records available or existing that might inform the evaluator's opinion?

Answering these questions before making a referral helps ensure the evaluation is scoped correctly from the start.

Getting the Right Evaluation

The quality of any evaluation depends on asking the right question at the outset. That means understanding whether your concern is about safety, functioning, or both, and communicating that clearly when making a referral. In practice, the most important step is not selecting a particular type of evaluation, but clearly defining the questions that need to be answered.
