The Harrison Assessment is a pre-employment and talent development tool used by organizations worldwide to evaluate job fit through its unique paradox theory framework. Unlike traditional personality tests, the Harrison Assessment measures 24 key work preferences and traits to predict job performance and engagement. This guide covers what the test measures, how it works, who uses it, and what you can expect as a candidate.
The Harrison Assessment was developed by Dr. Dan Harrison in the 1990s after extensive research into the psychological drivers of job success. Unlike traditional aptitude or IQ-based pre-employment tools, the Harrison Assessment is grounded in the enjoyment-performance model — the idea that people perform best in tasks they genuinely enjoy. This principle forms the foundation of the assessment's design.
At the core of the Harrison Assessment is paradox theory. This framework proposes that every positive behavioral trait has an equal and opposite counterpart that must be balanced to avoid dysfunction. For example, a candidate who scores high on "analytical thinking" must also demonstrate enough flexibility to avoid being perceived as rigid or indecisive. The assessment maps 24 pairs of paradoxical traits to reveal where a candidate's preferences fall along these spectrums.
Rather than labeling candidates with static personality types, the Harrison Assessment produces a job fit score — a percentage match between the candidate's preference profile and the behavioral requirements of a specific role. Employers can customize the job criteria to reflect what success looks like in their organization, making the assessment highly adaptable across industries and job levels.
This approach has made the Harrison Assessment a popular choice for employers who want to go beyond resumes and interviews. It is used not only for Harrison Assessment practice preparation but also for internal promotion decisions, team building, and individual development planning. Candidates who understand how the tool works are far better positioned to approach it with confidence and authenticity.
The Harrison Assessment evaluates candidates across 24 work preferences organized into four broad behavioral clusters. These clusters cover the full range of workplace behaviors that predict success in most professional roles.
This cluster assesses how candidates interact with others at work. Traits include warmth and empathy, collaboration, assertiveness, and diplomacy. Employers in customer-facing industries — such as healthcare and retail — weight these traits heavily when building their job fit criteria. Candidates preparing for Harrison Assessment tests should reflect honestly on their interpersonal style, since authentic responses produce more accurate job matches.
This cluster covers motivation, goal orientation, and resilience. Key traits include enthusiasm, results orientation, initiative, and persistence. The paradox theory dimension is especially visible here: a candidate who scores high on "persistence" without corresponding "flexibility" may be flagged as potentially inflexible under changing conditions. Understanding this balance is critical for anyone taking a Harrison Assessment pre-employment test.
Thinking style traits measure cognitive preferences — not cognitive ability. They include analytical thinking, creativity, attention to detail, and systems thinking. These differ fundamentally from cognitive aptitude tests; no answer is objectively correct. Many employers pair the Harrison Assessment with a separate cognitive ability test to get a complete picture of a candidate's capabilities alongside their preferences.
The self-management cluster examines self-discipline, stress tolerance, and work ethic. Traits include self-improvement orientation, consistency, emotional control, and accountability. These traits are particularly relevant for remote and autonomous roles, where self-direction is essential. Candidates can explore more about how to prepare for the Harrison Assessment to understand how self-management traits are weighted in different job profiles.
Each of the 24 traits is linked to a paradoxical counterpart. The assessment does not reward extremes — scoring too high or too low on either side of a paradox pair can indicate a potential workplace risk. For instance, high "frankness" paired with low "diplomacy" might predict interpersonal conflict in team settings. This nuanced model is what distinguishes the Harrison Assessment from simpler tools like the DISC assessment or basic Big Five personality surveys.
The Harrison Assessment occupies a distinct position in the pre-employment testing landscape. Here is how it compares to the most common alternatives:
Overall, the Harrison Assessment is best suited for employers who want a scientifically grounded, customizable tool that goes beyond broad personality categories to predict real-world job performance and employee engagement.
The Harrison Assessment is used by thousands of organizations globally, spanning industries including financial services, healthcare, retail, hospitality, and professional services. It is typically administered during the mid-to-late stages of the hiring process, after initial resume screening and first-round interviews have already narrowed the candidate pool.
Common users of the Harrison Assessment include large enterprise employers who need to make high-volume hiring decisions at scale, as well as mid-sized organizations focused on reducing turnover in key roles. Because the job fit criteria can be customized for each position, the assessment is equally useful for frontline roles and senior leadership positions.
Beyond hiring, many organizations use the Harrison Assessment for internal talent development — identifying high-potential employees, supporting succession planning, and building self-awareness among existing team members. In this context, candidates may encounter the Harrison Assessment even after they are already employed. Preparing with Harrison Assessment practice tests is equally valuable for internal promotion scenarios.
Because the Harrison Assessment is preference-based rather than knowledge-based, preparation looks different from studying for a cognitive or skills test. The goal is not to memorize correct answers but to develop self-awareness and comfort with the format so you can respond authentically and efficiently.
Start by reviewing what the 24 traits measure and thinking honestly about where your own preferences fall. Consider past jobs, projects, or team dynamics where you felt most engaged and effective — these experiences often reveal your genuine work preferences more accurately than abstract self-reflection. Candidates who approach the Harrison Assessment with this mindset tend to produce job fit scores that accurately reflect their potential.
It also helps to practice the ranking format itself. The Harrison Assessment presents groups of statements that you must rank in order of preference. This format can feel unfamiliar at first, especially compared to multiple-choice aptitude tests. Using Harrison Assessment practice materials helps you build comfort with the ranking mechanic so you can focus on authentic responses rather than format confusion during the real test.
