Pre Employment Tests: 10 Types and When to Use Each
Pre employment tests are standardized, scored exercises that measure what a résumé cannot show: job knowledge, skill on real tasks, reasoning, judgment or work style. The right test depends on the job. Use a knowledge test or work sample when you can name the skill, and treat personality and integrity tests as supporting evidence only.
This guide is for hiring managers, HR generalists and training companies that screen candidates for clients. It sorts ten test types by what they measure, when to use them and what to watch for, then shows how to order them and check fairness. It rests on U.S. government guidance, the text of the federal Uniform Guidelines and one research summary. It is general information, not legal advice.
Key takeaways
- Match the test to evidence you can defend: knowledge tests and work samples for skills you can name, and ability, judgment or style tests only when a job analysis shows they matter.
- Put cheap, automated tests early and rater-heavy ones, such as work samples and structured interviews, near the end.
- Pass rates multiply across stages, so each stage can clear the four-fifths check while the whole process fails it. Track both.
- An employer stays responsible for a test’s validity even when a vendor supplies it, according to the EEOC.
What do pre employment tests measure?
Pre employment tests measure what a candidate knows, can do on a job-like task, can reason through, or tends to do at work. Knowledge tests and work samples observe skills directly. Ability, judgment and style tests infer traits, so they need stronger evidence that the trait matters in the job.
Vendor guides that rank for this topic usually list the same test families without comparing build effort, evidence or fairness risk. The tables below add those columns, so you can choose by situation instead of by product category.
Which 10 types of pre employment tests exist, and when should you use each?
Ten types cover most hiring: job knowledge, work sample, cognitive ability, situational judgment, personality, integrity, structured interview, biodata, language and physical ability tests. The table gives each one’s best use and main watch-out. Most entries follow a U.S. Department of the Interior overview of assessment tools.
| Type | What it measures | Use it when | Watch out for |
|---|---|---|---|
| 1. Job knowledge test | Technical or subject knowledge, like a licensing-style exam | The competency is highly technical and cannot be learned on the job | Hard to build and maintain in-house; needs subject matter experts and regular review |
| 2. Work sample | Performance on tasks that mirror the real job | The role has concrete tasks and you have raters; place it near the end of the process | Rater time. Observers and task complexity drive cost, and raters need a scoring guide |
| 3. Cognitive ability test | Reasoning and information processing | The job is complex and people must learn new information quickly | Historically prone to subgroup differences, so combine with other tools and monitor pass rates |
| 4. Situational judgment test | Choices in realistic work scenarios | The role involves heavy interpersonal contact, or is managerial | Scenarios need expert input; video costs more than text |
| 5. Personality inventory | Motivations, interests and work styles, by self-report | The role is team-based or high-contact, as one input among several | Candidates can shape their answers; never use it alone as a pass-fail gate |
| 6. Integrity test | Attitudes and past behavior about honesty and rule-following | The role handles cash, stock or access to customers’ property | Evidence varies by vendor; ask for validity evidence for your job type |
| 7. Structured interview | Job-related competencies, scored on a set scale | You need to judge soft skills; use it near the end of the process | Time-intensive; every candidate gets the same questions in the same order, rated on the same scale |
| 8. Biodata | Past experiences and behaviors, from multiple-choice questions | Applicants are entry-level with little work history | Psychometrically complex; best built by professionals with test-development experience |
| 9. Language proficiency test | Reading, writing, speaking or listening in a language | The job needs that language at a defined level | Setting the bar above what the tasks need can screen out people for no job reason |
| 10. Physical ability test | Strength, stamina or other physical performance | The job is physically demanding and its tasks are well defined | Can raise Americans with Disabilities Act issues if it resembles a medical exam; ask counsel |
Rows 1 to 5, 7 and 8 follow the Interior overview. Rows 6, 9 and 10 reflect vendor guides and editorial judgment, so treat them as starting points. Some guides also list emotional intelligence, culture fit and drug tests. This list leaves them out because the government overview does not profile them, and drug-testing rules vary by state.
Not all ten earn their place equally. In a 2022 update to selection research by Sackett and colleagues, summarized by the Society for Industrial and Organizational Psychology, “structured interviews had the highest mean operational validity (r = .42)” and cognitive ability had an estimate of .31. Those are averages across many jobs, not a promise for yours.
Situational judgment tests are the type most teams can write themselves, because a scenario is a short story plus options. If you plan to, our guide on how to build a situational judgement test covers the build.
Pro tip: Pilot Work Samples With Two Employees. Before a work sample goes live, have two current employees do the task and score them independently. If the raters disagree by more than one point on a five-point scale, fix the scoring guide before any candidate sees it.
Which pre employment test should you start with for your situation?
Start with the skill you can name. For technical roles that means a job knowledge test or work sample. For high-volume entry-level roles, a short knowledge or judgment screen works. For managers, a structured interview with a realistic task fits. Add ability or style tests only after a job analysis shows they matter.
The table below is editorial judgment built from the sources above, not a published standard.
| Hiring situation | Start with | Add later | Be careful with |
|---|---|---|---|
| High-volume entry-level role | Short job knowledge test or text-based situational test | Structured interview for finalists | A cognitive test as the only filter |
| Technical specialist | Job knowledge test | Work sample | Personality results as a gate |
| Customer-facing or team role | Situational judgment test | Structured interview | Personality as the sole screen |
| Manager or team lead | Structured interview | Work sample, such as a planning or coaching task | Cognitive-only screens |
| Role with access to cash, stock or property | Job knowledge or situational test | Integrity test as one input | Rejecting on an integrity score alone |
| Role needing a second language | Language test at the level the tasks need | Work sample in that language | A bar above what the job uses |
Safety-critical sectors can add rules of their own. For airlines and maintenance organizations, our guide to pre-hire aptitude assessments for airlines and MROs covers that case. This guide stays general.
In what order should pre employment tests run?
Run low-cost, automated tests first and rater-heavy ones last. The Interior overview places structured interviews and work samples near the end of a multiple hurdle process. Fewer candidates reach the costly stages, and each gate gives you a point to check fairness.
Checking matters at every gate because pass rates multiply. The Uniform Guidelines at 29 CFR 1607.4 say a selection rate below four-fifths (eighty percent) of the highest group’s rate “will generally be regarded” as evidence of adverse impact. The same section adds that smaller differences “may nevertheless constitute adverse impact” where they are significant in statistical and practical terms. It also says greater differences may not count when based on small numbers. So the rule is a screening benchmark, not a verdict.
Here is an illustrative two-stage process. The numbers are invented.
| Step | Group A pass rate | Group B pass rate | Group B rate divided by Group A rate |
|---|---|---|---|
| Stage 1: knowledge test | 60% | 51% | 0.85 |
| Stage 2: work sample | 50% | 45% | 0.90 |
| Both stages combined | 30.00% | 22.95% | 0.77 |
Neither stage falls below 0.80, yet the combined ratio does. Group A’s overall rate is 0.60 times 0.50, and Group B’s is 0.51 times 0.45. Whether the law looks at each stage or at the whole process is a question for counsel. Tracking both costs nothing extra.
What makes a pre-employment test defensible?
A test is easier to defend when you can show it measures what the job requires. The EEOC says an employer can meet the job-related standard by showing a test “is necessary to the safe and efficient performance of the job.” It adds that the employer “is still responsible for ensuring that its tests are valid” even when a vendor supplies them.
Those points come from the EEOC’s guidance on employment tests and selection procedures, issued in 2007. The same page says employers must provide reasonable accommodations in how tests are administered, and that a test should measure the skill, not the candidate’s impairment.
Enforcement priorities have also moved. In April 2025, Executive Order 14281 told federal agencies to deprioritize enforcement of disparate-impact liability. A July 2025 note from the UNC School of Government says the statute still declares disparate impact unlawful and that applicants keep the right to sue. That note does not cover later developments, so confirm current rules and state law with counsel.
For each test you use, keep a defensibility file with these records:
- A short job analysis listing the tasks and skills the test reflects
- The vendor’s validity evidence, plus your reasoning for why it fits this job
- The test version, the scoring key, and the pass mark with the reason for it
- How accommodation requests are received and handled
- Applicant counts and pass rates by group at every stage
- The date of each review and who did it
A pass mark needs a rationale, not a round number. Our guide to setting cut scores for professional training courses explains how standard setting works.
Pro tip: Log Pass Rates By Stage From The First Candidate. Section 1607.4 says users of selection procedures should keep records of how those procedures affect groups by race, sex and ethnicity. Build the sheet before launch, because rebuilding it from an applicant system export later is slow and error-prone. Ask counsel how to collect group data lawfully.
What should you do next?
Pick one open role and write down the three tasks that matter most. Choose the one test type from the first table that measures those tasks directly, a knowledge test or work sample in most cases, and add a structured interview for finalists. Pilot it with current employees before candidates see it.

Frequently asked questions
What are the most common types of pre-employment tests?
Common types are job knowledge tests, work samples, cognitive ability tests, situational judgment tests, personality inventories, integrity tests, structured interviews, biodata, language tests and physical ability tests. Vendor guides also add emotional intelligence and culture fit tests. Knowledge tests and work samples measure skills directly, which makes them the easiest to tie to a specific job.
Are pre-employment tests legal in the U.S.?
Federal law does not ban them. The EEOC says a test that screens out a protected group disproportionately must be job-related and consistent with business necessity, and employers must offer reasonable accommodations in test administration. Rules vary by state and enforcement priorities have shifted, so check your process with employment counsel. This is general information, not legal advice.
Do pre-employment tests predict job performance?
Some do, and the evidence differs by type. In Sackett and colleagues’ 2022 update, as summarized by SIOP, structured interviews had a mean validity of .42 and cognitive ability .31. Those are averages across many jobs, so a test still needs evidence that it fits your role before you use it to screen people out.
Should you use more than one pre-employment test?
Usually yes. The Interior overview says cognitive ability tests should be combined with other tools to reduce potential adverse impact, and it places structured interviews and work samples near the end of a multi-stage process. Each added stage compounds any pass-rate gap, so check fairness for each stage and for the whole process.
Do candidates with disabilities need accommodations on pre-employment tests?
The EEOC’s guidance says employers must provide reasonable accommodations in how tests are administered, and a test should measure the skill the job needs, not the candidate’s impairment. Plan a simple way for candidates to request changes, such as extra time or another format, and ask counsel how to handle individual requests.
What is the best pre-employment test for a small business?
No single test is best. If you can name the skill, start with a short job knowledge test or a work sample scored against a written guide. The Interior overview says job knowledge tests are hard to build in-house, so buy or borrow validated content where you can, and add a structured interview for finalists.
