Precise Cognitive Testing to Keep Your Workplace Safe
Relying on guesswork for cognitive health? That's a gamble. And in the workplace, it's a risk you can't afford. Precision matters—because safety isn’t just a priority; it’s everything.
That’s why we created Creyos Attrea. With Attrea, employers can conduct automated cognitive testing in less than 5-minutes that evaluates employees on skills vital for a safe and productive workplace.

Non-Invasive
Common fitness for duty tests, like drug and alcohol screening, are invasive, difficult to administer, and costly. Attrea is completed entirely online, requires no special training to administer, and can be done in a supervised or unsupervised setting.
Measures Root-Cause
Lifestyle biomarker trackers, like sleep trackers or similar devices, assess factors affecting cognition but not the cognitive skills directly. Attrea specifically assesses the cognitive functions in a cause-agnostic way.
Objective Evaluation
Many common tools are highly subjective, relying on checklists or questionnaires and self-reported symptoms. With Attrea, providers remove employee perception from the equation and measure a worker’s precise cognitive function.
Flexible Administration
Hardware for many fitness for duty evaluations is often not rugged enough to withstand certain workplace environments, yet requires on-site administration. Attrea only requires a mobile device, tablet, or computer, and tests can be taken at home or on site.
Testing that Fits Anytime, Anywhere, for Every Team
Creyos Attrea adapts to your needs—whether it's on-site testing, remote, or on the go. It’s quick, easy, and designed to fit into any routine. Because when it comes to engaging employees in workplace health initiatives, flexibility isn’t a luxury; it’s a necessity.
Anonymous Self-Serve Model
Employees take the assessment on their own at the beginning of the workday and view their own results. If an anomaly in performance is detected on the assessment, the employee is encouraged to seek out the guidance of a supervisor.

Supervised Model
A supervised model, where an employee’s assessment is flagged and an email is immediately triggered to the supervisor to proactively follow up. The supervisor can then carry out a standard protocol to determine whether the employee is fit for duty that day.
