What are Workplace Behavioral Assessments?
A behavioral assessment is a psychometric tool used by employers to understand how someone naturally communicates, leads, and works so organizations can better predict role fit and performance.
Thomas uses the proven DISC model as the basis for our Behavioral Assessment, surfacing the traits that impact performance, team fit, and leadership potential at work. We ask 24 questions to build a behavioral profile in under 8 minutes, giving you instant insight into how someone works before you make a hiring decision.
What that means for your business:
- Avoid costly mistakes with mishires that can drain up to $20,000–$50,000 per bad hire.
- Faster onboarding reduces ramp-up time by up to 30% when you know how your people learn.
- Stronger teams boost team output by up to 25% through improved communication and collaboration fit.
Resumes show experience. Interviews show confidence. Behavioral assessments give you the missing data that takes time to discover - how someone will perform, lead, and collaborate in real-world conditions.
Why use Workplace Behavioral Assessments?
Great resumes can hide poor role or team fit. Confident interviews can mask future friction at work. And potential does not always translate into on-the-job performance.
That’s where Thomas comes in.
Our behavioral assessments help employers make smarter, faster hiring and development decisions from the start.
Organizations use them to:
- Reduce early attrition by understanding role, team and culture fit.
- Improve productivity by aligning work styles, communication, and leadership expectations.
- Support internal mobility by identifying leadership potential that does not show up on a CV.
Because instinct does not scale, but data does.
A better indication of potential
The Thomas Behavioral Assessment helps you understand how candidates prefer to communicate, make decisions, and operate under pressure - so you can make unbiased decisions and align roles to strengths, not assumptions.
Built on the DISC model and delivered through the Thomas Assess platform, it gives your teams instant insight into:
- Communication style – how they engage with peers, managers, and clients.
- Pace and decisiveness – whether they move fast, methodically, or need direction.
- Structure vs. adaptability – how they respond to ambiguity and change.
- Preferred environment – where they’ll thrive (e.g. collaborative vs. independent roles).
