How PDP Behavioral Assessments Outperform Traditional Personality Tests and Overcome Workplace Skepticism
Your people are your most important asset. But attracting, engaging, and retaining talent is an immense challenge—it’s possibly the most difficult challenge in businesses.
One solution? Behavioral assessments.
“Oh no,” you may be thinking. "I need a real solution."
We hear you. Many companies hesitate to give behavioral assessments a shot. Maybe you’ve tried one that didn’t seem accurate or valuable. Perhaps it didn’t have a clear impact on your company or offer a return on investment. Maybe you’ve never tried behavioral assessments because they seem like pseudo-scientific junk.
But what if we told you that there’s a behavioral assessment that is 98% accurate? And that you can use its results to make measurable improvements to hiring, retention, team dynamics, and leadership performance?
There is—it’s ProScan.
Behavioral scientists, statisticians, and industry leaders developed ProScan using a rigorous testing procedure on working adults (not students like many others) and statistical analyses to produce accurate and useful behavior results.
Key PDP ProScan Takeaways
- It’s accurate. 98% of people when researched agree that their ProScan results correctly describe them.
- It’s reliable and valid. ProScan has consistently tested reliably for over 40 years, with the most recent tests conducted in 2021 on over 39,000 people.
- It’s quick. Respondents can on average complete PDP ProScans in 5.1 minutes.
- It’s unbiased. Research has found that PDP ProScans don’t result in disparate results for different demographic groups—all your applicants have an equal opportunity to perform well, regardless of their background.
- It works. ProScan genuinely impacts how businesses hire and manage their people and creates a quantifiable return on investment.
In other words, ProScan isn’t just another behavioral assessment. It’s proven to help organizations hire the best people, retain and promote top talent, and enable effective team communication. Behavioral assessments—done right—can save you time and money on hiring. They can help you find the candidates that will ensure you build a functional team and productive, positive team culture.
Before you give up hope on behavioral assessments, here’s how PDP Global’s behavioral assessments work and why they’re so effective.
Why Behavioral Assessments Have a Bad Reputation
Long-term success requires that business strategy syncs up with people strategy. It’s about alignment: developing productive teams that rally around your business goals can generate successful business outcomes. Behavioral assessments can help you understand your people, providing insights that can help you create that alignment. But, many behavioral assessments are compared to personality tests that fail to provide accurate or useful results, leaving a bad reputation across the board. To make matters worse, assessments may even be misused and create additional legal risks.
Comparison to Personality Tests
Personality tests are becoming increasingly popular in hiring scenarios with the roughly $7.4 billion market in 2021 expected to grow to $16.4 billion by 2028. The emphasis of knowing whether candidates are a right fit for an organization is more important than ever thanks to Covid and the rise of remote work. However, “personality test” and “behavioral assessment” are often used interchangeably, when in fact they can be quite different.
Personality Test Characteristics
Standard personality indicators provide a broad "snapshot" but often fall short in high-stakes professional environments.
- Static Measurements: These tests focus on character traits formed by genetics and environment that are often described as unchanging. Behavior is how someone acts out their personality and adapts to their surroundings. While personality traits are hard-wired, behavioral response can be coached and developed over time.
- Lack of Contextual Flexibility: They fail to account for how different scenarios or surroundings change a person's response. Someone who is typically easy-going may respond differently if placed into a stressful situation.
- Scientific Reliability Gaps: Many popular tests, such as the MBTI, lack evidence of reliability and validity; up to 75% of users receive different results when tested twice.
- Non-Professional Design: Many tools were developed without formal training in psychology or scientific test development, making them unsuitable for business-critical decisions.
- Restricted for Hiring: Leading personality tests like DiSC explicitly state on partner websites they should not be used for pre-employment screening as they do not provide a complete picture for hiring.
Behavioral Assessment Characteristics
Behavioral assessments represent the evolution of workforce science by turning personality data into actionable performance insights.
- Focus on Adaptation: While personality is hard-wired, behavioral assessments measure how someone acts out their personality and adapts to their environment.
- Coachability & Development: Unlike fixed traits, behavioral responses can be coached and developed over time, allowing for long-term employee growth.
- Practical Application: These assessments take data one step further by showing how to practically apply behavioral information in real-world work situations.
- Predictive Hiring Data: Built on sound scientific methods, behavioral assessments reliably correlate candidate results to job success and team effectiveness.
| Feature | Traditional Personality Tests | PDP Behavioral Assessments |
| Primary Focus | Measures "Who you are"; static character traits from genetics and environment. | Measures "How you act"; observable, dynamic responses to workplace environments. |
| Predictive Power | Low/Mixed. Traits rarely map cleanly to specific job performance outcomes. | High. Validated to predict job-specific performance, adaptability, and leadership. |
| Consistency | Unreliable. Many personality test users receive different results when retaken. | Highly Reliable. Built on Confirmatory Factor Analysis (CFA) for consistent, scientific results. |
| Workplace Utility | Mostly used for team bonding or general self-awareness. | Optimized for all stages of the employee lifecycle from hiring to development. |
| Stress Monitoring | Typically does not track real-time stress or energy levels. | Identifies specific stress responses and "energy drain" in various situations. |
| Legal Status | Often explicitly discouraged for pre-employment screening. | EEOC & ADA Compliant. Legally validated for use in the hiring process. |
Misuse of Workplace Application
When used appropriately, behavioral assessments can help individuals and teams better understand their strengths and communication styles. But when misused, behavioral assessments can introduce bias into hiring decisions and even reduce workplace diversity.
It is possible to identify the existence of certain disabilities that the test taker may have depending on the behavioral assessment. For example, answers to questions like “You are always cheerful” or “You have confidence in yourself” can be linked to depression. When used in a hiring context, this type of survey contributes to the discrimination of people with disabilities and can even lead to lawsuits.
Under the Americans with Disabilities Act (ADA), employers cannot ask potential job candidates to take a medical exam. But some personality tests, like the Minnesota Multiphasic Personality Inventory (MMPI), can provide information indicative of a mental illness diagnosis. In one case, the court of appeals determined that administering the MMPI to qualify someone for a promotion violated the ADA.

Even an unbiased behavioral assessment can be turned into an inappropriate hiring tool if administered incorrectly. Let’s say an HR Director distributes a behavioral test based only on one type of the protected classes like race, religion, or age. Then, bias is introduced outside of the function of the behavioral assessment and can land the organization in hot water.
What Makes PDP Behavioral Assessments Actually Work
The behavioral assessments we offer are different because they are: founded on decades of research, accurate and valid, completed quickly in 5.1 minutes on average, and designed to eliminate bias within the hiring process.
Why Choose PDP Over Traditional Personality Tests?
• Scientifically Validated for Hiring: Unlike many popular personality indicators, PDP is legally validated for pre-employment screening (EEOC and ADA compliant) and specifically designed to predict job performance.
• The "Gold Standard" of Accuracy: While competitors use Exploratory Factor Analysis (EFA), PDP has achieved Confirmatory Factor Analysis (CFA) (the highest level of statistical rigor) conducted on a massive scale (39,000+ working adults).
• Measures Stress & Energy Drain: Beyond fixed traits, we measure dynamic factors like "Energy Style" and "Satisfaction Level," allowing managers to identify potential burnout before it happens.
• High Precision, Low Bias: Using a 5-point Likert scale (rather than binary yes/no questions), our assessments capture the nuances of human behavior, resulting in a 98% accuracy rating as reported by users.
• Rapid & Actionable Insights: Designed for the fast-paced business world, the assessment takes 5.1 minutes on average to complete and provides 140,000+ possible profile permutations, moving beyond "pigeonholing" individuals into 16 simple types.
Research

- Built with Workplace Focus: Developed in the 1970s by an interdisciplinary team of academics and business leaders, PDP’s original assessments were grounded in large-scale studies of thousands of working adults and designed to measure five core traits: Dominance, Extroversion, Pace, Conformity, and Logic.
- Gold-Standard Statistical Rigor: PDP Global validates its behavioral assessments using Confirmatory Factor Analysis (CFA) (a higher standard than Exploratory Factor Analysis) to ensure each trait is distinct, consistent, and predictive of performance. Few competitors complete this level of testing, and PDP has repeated CFA validation three times to prove reliability and consistency.
- Ongoing Validity Study Since 2021: PDP Global launched its most recent long-term CFA study in 2021 to evaluate updated assessment language for greater accuracy. Results confirmed the original 4-factor model plus Logic as a distinct trait, demonstrating the assessment is reliable, valid, and reproducible.
- 39,000+ Case Study Sample: Our core research was validated against a massive sample of 39,000 working adults (as opposed to undergraduate students), ensuring the data reflects real-world workplace dynamics rather than controlled lab settings.
- Psychologist-Recognized Research Standards: PDP Global’s assessments are developed with exceptional scientific rigor and have been endorsed by professional psychologists who vouch for the integrity of our methodology.
Accuracy
- 98% User Agreement: Respondents consistently agree their results are "spot on."
- Excellent Internal Reliability (α = 0.94): ProScan achieved a Chronbach’s alpha of 0.94, far exceeding the accepted benchmark of 0.70 and indicating exceptional alignment of questions within each trait (Research 1.10).
- Strong Test-Retest Consistency: PDP assessments deliver dependable results over time, with reliability scores in the 0.70s and 0.80s across traits, meaning individuals receive consistent outcomes when taking the assessment multiple times, often exceeding the stability of other nationally normed tests (Research 2.1).
Validity
- Proven Validity: PDP Global assessments are scientifically validated through exploratory and confirmatory factor analyses, with internal validity consistently confirmed and replicated again in a 2021 study
- Strong Concurrent Validity: ProScan correlates with other established behavioral assessments, with correlation coefficients ranging from .39 to .87, indicating moderate to very strong alignment.
- Predictive Validity for Job Success: ProScan results consistently predict future job performance, helping organizations select the right people for the right roles.
Zero Bias
- EEOC and ADA Compliant: Our assessments meet and exceed the standards set by the Equal Employment Opportunity Commission and the Americans with Disabilities Act for pre-employment selection, following the Employment Test and Selection Procedures policy that:
“Employers should ensure that tests and selection procedures are not adopted casually by managers who know little about these processes. A test or selection procedure can be an effective management tool, but no test or selection procedure should be implemented without an understanding of its effectiveness and limitations for the organization, its appropriateness for a specific job, and whether it can be appropriately administered and scored.”

- Independently Audited for Fairness: We conducted a comprehensive research study to ensure there is no "disparate impact" or adverse bias against protected groups.
- Designed to Prevent Biased Hiring: Assessments are carefully constructed to support objective, non-discriminatory hiring decisions without unintentionally disadvantaging protected groups.
- Certified Administration & Interpretation: PDP offers four EEOC-compliant certification programs to ensure assessments are properly applied with full understanding of effectiveness, limitations, and job relevance.
- Trusted Legal Confidence: Employment lawyers have expressed their confidence that PDP assessments align with U.S. state and federal regulations, helping organizations make compliant, unbiased hiring decisions.
PDP Behavioral Assessment Employment Use Cases
PDP’s behavioral assessments can be used to solve a range of challenges facing your organization such as hiring and retention, team communication, and leadership/management development.

Hiring and Retention
Selecting and keeping talent is a massive challenge. Bad hires are costly, and bringing the wrong person to the team can hurt morale.
PDP helps you find the right person for the right role. A robust JobScan report looks at your top performers and helps you identify the traits that lead to success, along with the behaviors you feel are most important at this time for the position. It then provides you with a list of keywords you can use to create job descriptions and advertisements that attract the right applicants, supplying you with a steady pipeline of strong candidates.

Next, the candidates complete the Applicant ProScan behavioral assessment quickly in 5.1 minutes on average to obtain an inventory of their individual behavioral traits. You can easily see who has the traits that are most consistent with success in your teams. To ensure hiring the best, JobScan’s Interview Guide prompts behavioral interviewing questions that are objectively derived based on applicant’s traits compared to the required position traits.
Real-World Application
Companies around the world use our assessments to improve hiring and retention outcomes. For example, a US call center that used PDP assessments saw the following benefits:
- 10% increase in screening capacity
- 10% increase in length of employee tenure
- Recruiting staff needed reduced by 3.5 full-time positions
“The results of the PDP solution implemented have surpassed our initial expectations. We have been able to tap into new labor markets and realize greater recruiting success in a period of very aggressive growth. We look forward to expanding the role PDP plays in our organization beyond recruiting. If you hire with any sort of regularity, you need this tool.” —Call Center Human Resource Manager
Team Communication
Strong performance requires your people to pull together. PDP helps align your people with your team culture and build communication skills that enable them to solve your toughest business problems.
Our TeamScan tool shows you the unique dynamics of your team—their traits, energy levels, and motivators. It also allows you to find effective leaders and put your team members in positions where they’ll thrive.
Our system has helped numerous organizations build high performing teams, improve their culture, and become more effective. For example, Cure 4 the Kids Foundation turned their culture around from one that was conflict-avoidant to one that is transparent and open by using TeamScan. Their employees became more engaged, built trust, and experienced a boost in morale across the board. The benefits they saw include:
- Ranked 32 on the 50 Best Nonprofits to Work for in the U.S.
- Ranked 2,603 on the Inc. 5000 Fastest Growing Small Businesses
- Earned Gold Standard award from the Joint Commission for four consecutive inspections over 13 years
“Investing in our leadership team has created incredibly engaged and inspired teams in each department, working collaboratively.” —Annette Logan, Cure 4 the Kids Foundation Founder/CEO
Leadership and Management Development
Leadership is the art of building an effective team culture. It requires both strategic vision and the ability to rally teams around that vision. Without effective leaders, your people become disengaged, make poor decisions, and leave to find work elsewhere.
PDP gives you the insight you need to lead effectively and build a high-performance work culture. It helps you understand the traits that make effective employees in your company so you can hire more of them, what motivates your employees so you can optimize productivity, and also helps you shift the company culture so your employees are more engaged.
Our system has helped businesses of every size identify opportunities for improvement in their leadership styles and understand how to remediate those.
Real-World Application
For example, PDP provided the support Rose Chauffeured Transportation needed to establish effective and authentic communications with the company and ultimately build morale. The measurable benefits include:
- 44% reduction in employee turnover
- 75% growth in sales
- Employee morale is at an all-time high
"I worked 34 years in the corporate world before embarking on an entrepreneurial career. I knew managing a small business would be a challenge. I’ve used consultants successfully. Don Crosby of PDP Global is absolutely the best at handling and dissecting the faulty communication dynamics of any business and improving hiring procedures. He never offends, and his positive approach removes the barriers and obstacles we all encounter. The results have been no less than amazing.” —H.A. Thompson, Rose Chauffeured Transportation President and Founder
How PDP Compares to Popular Solutions on the Market
PDP Global’s assessments aren’t just effective—they’re also unique. There is nothing else on the market that works like them. In fact, 54% of PDP clients previously used a competing tool before switching to PDP. Here’s how the PDP system stacks up against other popular solutions.
DiSC Personality Profiles

The DiSC® Personality Profile is a widely respected tool based on the 1928 emotional and behavioral theory of William Moulton Marston. While not specifically designed to predict job performance, it has earned global popularity as a foundational resource for fostering self-awareness and improving communication within teams.
The Predictive Index

PDP Global’s ProScan and the Predictive Index are both widely used behavioral assessments designed to support hiring, team development, and workplace performance. While each tool offers valuable insights into individual work styles, organizations may find differences in approach, research foundation, and reporting depth. Explore our full comparison to see which assessment best fits your needs.
The Enneagram

PDP Global’s behavioral assessments and the Enneagram both aim to provide insight into how individuals operate, but they serve different purposes and are built on different foundations. The Enneagram maps people into one of nine personality types and is often used for self-awareness and personal growth, whereas PDP’s assessments are empirically developed with workplace research and statistical validation.
Culture Index
PDP Global’s behavioral assessments and the Culture Index both provide insight into individual work styles, but they differ in depth, reporting, and analytic focus. PDP’s assessments are designed to offer detailed, multi-dimensional profiles grounded in extensive research and validated against working-adult data, while Culture Index delivers a high-level snapshot of general traits. For a full side-by-side comparison of features, methodology, and workplace applications, see our detailed comparison page.
Big Five Personality Tests

The Big Five personality test is a proposed taxonomy of personality traits. It’s one of the most widely used taxonomies for understanding personality in current psychological science and is well-validated by numerous studies.
The Big Five model also has been useful for helping understand how personality can be related to health and mental health.
While personality tests that use the Big Five model are useful for understanding personality from a psychological point of view, it’s not clear that they can be usefully applied to work contexts.
It wasn’t designed specifically to predict job performance or help recruiters find ideal candidates. In one study of over 250 salespeople, it was found that self-efficacy was a better predictor of job performance than the Big 5 test. The personality traits measured are too general to be applied to specific roles.
In contrast, PDP Global’s assessments were designed specifically for application in a work context. Especially in the case of hiring, the JobScan module benchmarks the desired traits for a particular position, which the hiring professional can then compare individual applicant ProScan results to.
Behavioral Assessments Help You Understand Your People
The reason why many people are skeptical of the ability of a behavioral assessment to aid in finding and retaining qualified people is because several popular tests on the market are not structured or scientifically supported for that application. But, the right behavioral assessment can offer you something powerful—the ability to build cooperative, productive teams.
PDP’s surveys are objective and can be used for the hiring/screening and selection process; not all other tools can say this. The same traits and metrics used for hiring are the same used for managing, the same used for team building, and the same used for analyzing the organization’s culture.
Other competitors deploy a multitude of tests to address the suite of applications that PDP addresses with its behavioral assessment. With PDP, you have a common, consistent language for quantifying and identifying your people.
Each of PDP Global’s suite of behavior assessments has been rigorously constructed and statistically validated using working adults, not students, as the test group. PDP ProScans have also been battle-tested: over 5,000,000 surveys have been taken to date with a 98% accuracy rating and they create measurable returns on investment for a wide variety of organizations across 23 countries.
