How to Use Pre-Employment Assessments to Make Better Hires
If you’ve ever been stuck choosing between two strong candidates, or worse, made a hire who looked perfect on paper but didn’t work out, you know how tricky hiring can be. Interviews and resumes only tell part of the story, which leaves hiring managers guessing at how someone will actually perform once they’re in the role. That’s where pre-employment assessments can change the game.
These assessments provide data you can’t always get in an interview: how someone solves problems under pressure, whether they’ll mesh with your team’s culture, or if they have the technical expertise needed on day one. Used the right way, they can help you hire with more confidence and avoid costly mistakes. In the following sections, we’ll cover what pre-employment assessments are, the benefits and drawbacks, and the types of tests most companies use today.
What Are Pre-Employment Assessments?
Pre-employment assessments are structured tests or evaluations designed to measure a candidate’s skills, personality traits, or job-related abilities before they’re hired. Unlike resumes or interviews, which can be influenced by subjective impressions, these assessments provide objective data to help employers make more informed hiring decisions.
Think of them as a window into how a candidate might actually perform once they’re in the role. Assessments can evaluate a wide range of skills, including technical knowledge, problem-solving abilities, cultural alignment, and emotional intelligence. Some are quick online quizzes, while others involve real-world simulations that mimic the tasks of the job.
When used correctly, pre-employment assessments act as a supplement, not a replacement, for interviews and other parts of the hiring process. The goal isn’t to reduce candidates to a score but to add another layer of insight, giving hiring managers a clearer, more complete picture of each applicant.
Benefits of Using Candidate Assessments
Reduces hiring bias
Even the most experienced hiring managers can be swayed by unconscious bias. We naturally gravitate toward candidates who remind us of ourselves or who make a strong first impression, even if they aren’t the best fit for the job. Pre-employment assessments help level the playing field by providing standardized, data-driven criteria to evaluate every candidate. With consistent benchmarks, it becomes easier to compare applicants fairly and make decisions based on merit rather than instinct.

Weeds out unqualified candidates
When you’re flooded with resumes, it’s easy for underqualified candidates to slip through the cracks and eat up valuable interview time. Assessments allow you to identify clear dealbreakers early, like a lack of technical skills or required certifications, so only qualified applicants move forward. You’ll save time and keep the pipeline focused on candidates who are truly capable of performing the job.
Compares two or more top contenders
Sometimes you’ll find yourself choosing between two strong candidates. Both check all the boxes, but you need a way to break the tie. Assessments provide that extra data point to guide your decision. Whether it’s problem-solving ability, communication style, or adaptability, the results give you more confidence in selecting the candidate who’s most likely to succeed in the role.

Sheds light on blind spots
Interviews can reveal a lot, but they rarely uncover everything you need to know about a candidate. Pre-employment assessments can highlight skills or behaviors that might otherwise go unnoticed, such as leadership potential, learning agility, or work style preferences. These insights not only help you make a better hiring decision but also prepare managers to support the candidate effectively if they join your team.

Disadvantages of Using Pre-Employment Assessments
- Inconsistent results. If a test produces different outcomes each time a candidate takes it, it isn’t reliable. Always validate consistency before using it to guide hiring decisions.
- Limited scope. Assessments can measure technical skills or problem-solving abilities, but they don’t capture qualities like creativity, adaptability, or long-term potential. They should complement, not replace, interviews and other evaluation methods.
- Legal risks. Assessments must comply with Equal Employment Opportunity (EEO) standards, the Uniform Guidelines on Employee Selection Procedures (UGESP), and the Americans with Disabilities Act (ADA). Using tools that aren’t job-related can put your organization at risk of lawsuits.
- Longer hiring timelines. Adding assessments can extend the hiring process, which already averages three to six weeks in the U.S. Delays may cause top candidates to drop out or accept offers elsewhere.
Different Types of Pre-Employment Assessments
Job knowledge tests
Job knowledge assessments measure whether a candidate possesses the technical or theoretical expertise necessary to succeed in a role. For example, an IT help desk candidate might be tested on troubleshooting procedures, while an accountant could be asked to apply GAAP principles. These tests are best for positions where specific, pre-existing knowledge is essential and where on-the-job training won’t be sufficient.
Examples: SHRM HR Knowledge Exam, CPA practice tests, IT certification quizzes (e.g., CompTIA, Cisco).
Personality tests
Personality assessments evaluate behavioral traits to see how well a candidate may align with a role or company culture. They can help identify whether someone is empathetic enough for a customer service position or whether their natural style matches the demands of a sales role. While not perfect predictors of success, they provide insight into how a person may approach challenges and interact with others.
Examples: Myers-Briggs Type Indicator (MBTI), DiSC Assessment, Hogan Personality Inventory, Caliper Profile.

Cognitive ability tests
These tests assess mental capabilities such as critical thinking, numerical reasoning, and problem-solving. They’re instrumental when hiring for roles that require fast learning and complex decision-making, such as analysts, engineers, or management trainees. Because cognitive ability strongly correlates with job performance, many employers rely on these assessments to spot high-potential candidates.
Examples: Wonderlic Personnel Test, Criteria Cognitive Aptitude Test (CCAT), Revelian Cognitive Ability Test.
Behavioral assessments
Behavioral tests predict how a candidate is likely to act in specific, job-related situations. They’re valuable when hiring for roles that require teamwork, leadership, or client-facing responsibilities, as they demonstrate how a candidate may respond under real-world workplace conditions. For example, situational judgment tests can reveal whether someone is more likely to de-escalate conflict or escalate it further.
Examples: Predictive Index Behavioral Assessment, Situational Judgment Tests (SJTs), Gallup CliftonStrengths.
Skills tests
Skills tests evaluate whether candidates can perform practical, job-related tasks. They’re particularly effective for technical or specialized positions where hands-on ability is non-negotiable, like coding, data entry, or graphic design. For instance, a marketing coordinator might be asked to draft a short campaign brief, while a developer could complete a timed coding challenge.
Examples: Codility or HackerRank (for coding), Microsoft Excel tests, writing/editing assignments, and design challenges.
Integrity tests
Integrity tests aim to gauge honesty, ethics, and reliability. They can be instrumental in industries where employees handle sensitive information, financial data, or valuable inventory. For example, retailers often use them to reduce the risk of theft, while financial institutions rely on them to screen for trustworthiness.
Examples: Reid Report, Stanton Survey, and overt integrity questionnaires.
Emotional intelligence tests
Emotional intelligence (EI) assessments measure how well a candidate can perceive, interpret, and manage emotions. They’re a strong predictor of success in leadership, sales, and client-facing roles where empathy and communication are critical. For example, a manager with high EI may be better equipped to handle team conflict or motivate direct reports.
Examples: Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), EQ-i 2.0, Genos Emotional Intelligence Inventory.
Physical ability tests
For roles requiring strength, stamina, or agility, physical ability tests confirm whether candidates can safely perform the work. They’re most common in fields like construction, manufacturing, firefighting, or law enforcement. These assessments must be directly related to job duties and ADA-compliant to ensure fairness and legality.
Examples: Muscular strength and endurance tests, firefighter Candidate Physical Ability Test (CPAT), military-style fitness evaluations.
How to Choose the Right One
Not every job requires the same type of pre-employment assessment. The key is to align the test with the skills and qualities that are most critical for success in the role. Start by breaking down the day-to-day responsibilities of the position. If the work is highly technical, like accounting, IT, or engineering, a job knowledge or skills test may provide the most valuable insights.
For roles that depend on communication, collaboration, or leadership, behavioral or emotional intelligence assessments can reveal how a candidate might fit with your existing team. Customer-facing positions, such as retail or hospitality, may benefit from personality tests that measure traits like patience and adaptability. Meanwhile, physically demanding jobs require physical ability tests to confirm that candidates possess the necessary physical abilities to perform safely and effectively.
It’s also important to consider the candidate experience. The assessment should be relevant, straightforward, and respectful of a candidate’s time. A lengthy or unnecessary test can create frustration and cause strong applicants to withdraw from the process. The best assessments are short, job-related, and seamlessly integrated into your overall hiring workflow.
Best Practices for Pre-Employment Assessments
- Analyze the job first. Review the job description and talk with hiring managers to identify the skills and behaviors that matter most. Choose assessments that measure those specific qualities.
- Define success criteria. Decide upfront what a strong score or passing result looks like. Having benchmarks in place ensures consistency and helps avoid subjective interpretation later.
- Test all candidates the same way. For fairness and legal protection, apply assessments at the same stage of the process for every applicant. Inconsistent use undermines objectivity and opens the door to compliance risks.
- Consider the whole picture. Use assessments as one piece of the puzzle alongside resumes, interviews, and references. This balanced approach prevents you from over-relying on test results alone.
- Track effectiveness over time. Review whether high scorers actually succeed in their roles by looking at turnover, productivity, and ramp-up speed. If the data doesn’t align, adjust your assessment approach.
Common Mistakes to Avoid
- Using irrelevant tests. Administering assessments that don’t align with the role (such as a math-heavy test for a customer service job) wastes time and damages the candidate experience.
- Relying too heavily on scores. Treating results as a pass/fail decision ignores the bigger picture. Assessments should inform your choice, not make it for you.
- Dragging out the process. Multiple lengthy tests can frustrate candidates and cause strong applicants to drop out. Keep assessments short, relevant, and respect candidates’ time.
- Overlooking compliance. Tests must meet legal standards under the EEO, UGESP, and ADA. Failing to validate assessments can expose your organization to serious risks.
How Much Should a Pre-Employment Test Count?
Pre-employment assessments should inform your decision-making, not dictate it. The weight you give them depends on the role you’re filling. For highly technical jobs, tests that measure job knowledge or skills may play a larger role because they directly determine whether someone can perform critical tasks from day one.
For positions where training is provided or where soft skills are just as important as technical ability, assessment results should carry less weight. In these cases, interviews, references, and cultural alignment may tell you more about whether a candidate will thrive long-term.
The best approach is to strike a balance: use assessments as a strong data point, but always consider the full picture of a candidate’s background, experience, and potential. That way, you avoid over-relying on a single test score while still benefiting from the objectivity these tools provide.
The Future of Pre-Employment Assessments
Pre-employment assessments are evolving rapidly, shaped by technology and shifting hiring priorities. Here are the trends driving the future:
- AI-driven predictive analytics. These tools analyze large datasets to predict a candidate’s likelihood of success. They go beyond test scores, factoring in work history, skill growth, and performance patterns to support more accurate hiring decisions.
- Gamified assessments. Interactive scenarios simulate real-world tasks, such as handling a customer call or resolving a workplace issue. Gamification in recruiting keeps candidates engaged while revealing natural problem-solving and critical thinking skills.
- Virtual reality (VR) simulations. VR allows candidates to demonstrate abilities in realistic, risk-free environments. Industries such as construction, aviation, and healthcare already utilize simulations to assess safety awareness and technical skills.
- Skills-based hiring. Employers are shifting focus from degrees to demonstrable skills. Assessments that measure technical ability, adaptability, and learning agility will become increasingly valuable.
- ATS integration. Assessments are being built directly into applicant tracking systems, making it easier to deliver, score, and compare results alongside resumes and interviews without adding friction to the process.
The takeaway? Assessments are evolving beyond static questionnaires toward more innovative and engaging tools that better predict long-term success. Employers who adopt these innovations will gain a competitive edge in attracting top talent.

FAQs
Why do companies use pre-employment assessments as part of their hiring process?
Companies use pre-employment assessments to make more informed hiring decisions. These tools provide objective data to complement interviews and resumes, helping employers evaluate skills, personality traits, and job fit. They also give candidates who may not shine in traditional interviews another opportunity to demonstrate their strengths.
At what point should companies conduct pre-employment assessments in the interview process?
Timing depends on the role. Basic screening tests can be given early in the process to weed out unqualified candidates, while more detailed assessments are often used between the first and second interview stages. Some employers also incorporate short assessments into interviews themselves to gather different types of information.
How important are pre-employment assessments when choosing the best candidate?
Assessments should be considered one of several data points, not the sole deciding factor. In highly technical roles, they may weigh more heavily because job-specific skills are critical. For other positions, they serve as supplemental insight alongside interviews, references, and cultural fit.
Are pre-employment assessments legal?
Yes, pre-employment assessments are legal as long as they are job-related, consistently applied, and compliant with federal and state laws. Employers must follow Equal Employment Opportunity (EEO) guidelines, the Uniform Guidelines on Employee Selection Procedures (UGESP), and the Americans with Disabilities Act (ADA). Any test that unfairly discriminates against protected groups or resembles a medical exam could be challenged legally.
How accurate are pre-employment tests?
The accuracy depends on the type and quality of the assessment. Validated, well-designed tests can be strong predictors of job performance, especially cognitive ability or skills tests. Others, like personality tests, may provide useful context but are less reliable on their own. Choosing reputable, validated tools is key.
Do assessments replace interviews?
No. Assessments should never replace interviews. Instead, they work best as a complement, providing objective data to pair with the insights gained during a conversation. Together, they create a more complete picture of a candidate’s potential.
How long do pre-employment tests take?
Length varies widely depending on the test. Simple skills or screening assessments may take 10–20 minutes, while in-depth cognitive or personality tests can last 45–60 minutes. Employers should balance thoroughness with candidate experience, keeping tests as concise and relevant as possible.
