Assessment Companies and Pre-Employment Testing Vendors
Assessment Companies and Pre-Employment Testing Vendors
If you have applied for a job recently, there is a good chance the test you were asked to take wasn't written by the company hiring you. It was built by an assessment company, a specialist firm that designs, administers, and scores pre-employment tests on behalf of employers. Most candidates only learn the name when it lands in their inbox: SHL, Criteria, Hogan, eSkill, Empco, and dozens more.
These companies all measure the same handful of things, just in different formats and under different names:
- Cognitive ability - numerical, verbal, logical, and abstract reasoning under time pressure
- Personality and behavior - work style, motivations, and how you are likely to handle a role
- Situational judgment - workplace scenarios that ask what you would do and why
- Skills and simulations - typing, software, customer service, and job-specific task simulations
Your score usually isn't compared to a fixed pass mark. It is compared to other applicants or to a norm group, which is why familiarity with the exact format matters as much as ability.
This page explains how assessment companies work and why employers rely on them. It then takes a closer look at the 3 biggest names, SHL, Criteria, and Predictive Index, with an overview of each company and a sample question from its tests. A directory of other assessment companies follows, so you can find the one behind your test and go straight to the right practice. The page ends with answers to the questions candidates ask most.
What Are Assessment Companies?
An assessment company is a firm that builds, validates, and scores the tests employers use to screen job candidates. Assessment companies such as SHL, Criteria, and Hogan write the questions, set the scoring rules, and report your results back to the employer, so the employer doesn't need to design its own test. Some are psychometric assessment companies that measure reasoning ability and personality, while others focus on job-specific skills.
You will see these firms described in several ways. Employers often call them assessment vendors, HR teams may refer to their HR assessment services, and you may find them listed as pre employment testing companies or pre employment screening companies. Whatever the label, the role is the same: they supply the test and the scoring behind your application.
A Short History of Assessment Companies
Standardized testing at scale began during World War I, when the US Army used group exams such as the Army Alpha to sort recruits. Employers adopted the idea in the following decades, and industrial psychologists began designing tests specifically for hiring. Specialist assessment companies followed, including Predictive Index in the 1950s, SHL in the 1970s, and Hogan in the 1980s. The internet then moved testing online, which made it practical for pre employment testing services to send the same test to thousands of applicants at once.
How Assessment Companies Test You
When an employer chooses among assessment vendors, it picks a test that fits the role and emails you a link. You complete the test online, usually under a strict time limit. The assessment company scores your answers against a cutoff or a norm group and sends the employer a score or ranked report. Some pre employment screening companies bundle these tests with other checks, but the test itself is written and scored by the assessment company. Most tests fall into 4 types:
| Test Type | What It Measures | Well-Known Assessment Companies |
|---|---|---|
| Cognitive ability | Numerical, verbal, logical, and abstract reasoning | SHL Criteria Korn Ferry Watson Glaser |
| Personality and behavior | Work style, motivations, and reliability | Hogan Predictive Index SHL Caliper |
| Situational judgment | Decision-making in realistic workplace scenarios | SHL Aon |
| Skills and simulations | Typing, software, and job-specific tasks | Criteria Wonderlic |
Why Employers Use Assessment Companies
- Volume - a single opening can attract hundreds of applicants, and pre employment testing companies let employers narrow the pool faster than reading every resume.
- Consistency - every candidate gets the same questions, time limit, and scoring, which makes results easier to compare.
- Predictive value - structured assessments from psychometric assessment companies tend to predict job performance better than unstructured interviews.
- Defensibility - a validated test gives employers a documented, job-related reason for who moves forward, which is a major reason HR assessment services are so widely used.
What This Means for Your Test
Your score is usually ranked against other applicants or a norm group, not graded against a fixed pass mark. That makes the format itself a factor: candidates who have already seen the question types, timing, and scoring of their assessment company's test lose less time on test day. Below, you'll find the biggest assessment companies on the market, with a closer look at how each one tests and a sample question from each.
Featured Assessment Companies
We prepare candidates for tests from dozens of assessment companies. Here are 3 of the biggest names in pre employment testing: SHL, Criteria, and Predictive Index. Thousands of candidates have prepared for their tests with our PrepPacks™. Each section below covers who the company is, what it tests, and what to expect, followed by a sample question. You'll find more assessment companies in the directory below.
SHL
SHL is one of the largest assessment companies in the world. It was founded in the UK in 1977 as Saville and Holdsworth Limited, and its best-known products include the Verify ability tests and the OPQ personality questionnaire.
- Test types - cognitive ability, personality, motivation, situational judgment, technical skills, and job-specific competencies.
- Typical clients - employers that hire in volume and for technology roles, across apprentice, graduate, professional, and manager positions.
- Scale - SHL reports that 45 million of its assessments are taken every year around the world.
- What to expect - timed online ability tests such as Verify, plus personality questionnaires such as the OPQ that ask how you typically behave at work.
SHL tests show up in many different hiring processes, so the exact format depends on the employer and the role. Our SHL practice tests help you get comfortable with the question types and timing before test day.
Numerical reasoning is the SHL test most candidates expect. You get a table or graph and have to work out a figure from it, usually a percentage, a ratio, or a change over time. This question asks for a change in an unemployment rate, which adds a step: the graph gives head counts, so you have to build the rates yourself.
How to Approach This Question
- Pin down what's asked - the question wants the change in a rate, for one group, between 2 specific years.
- Pull only the relevant figures - take the counts for that group in those 2 years and ignore everything else on the graph.
- Turn counts into rates - divide the unemployed graduates by the total graduates for each year.
- Subtract, later minus earlier - the sign of your result tells you whether the rate rose or fell.
- Check the unit - the answer options are in percentage points, so make sure you haven't calculated a percent change instead.

SHL numerical reasoning tests measure how well you can interpret numerical data and draw the right conclusion from it. Questions are built around tables, graphs, and charts, and the math is usually basic: percentages, ratios, averages, and changes over time. The difficulty comes from reading the data accurately while the clock is running.
SHL offers more than one version. The interactive version asks you to work with the data directly, for example by dragging answers into a table or adjusting a chart, while the multiple-choice version works like this question. Question counts and time limits differ by version, so check your invitation email to see which one you've been given. As with most SHL ability tests, your score is typically compared with a norm group, not graded against a fixed pass mark.
This question tests whether you can tell a count from a rate. The graph gives head counts of graduates, but the question asks about the unemployment rate, which is the unemployed share of the total. Comparing the raw counts instead of building the rates is an easy way to go wrong.
The second skill is the unit. As the explanation shows, the rate falls from 9.5% to 8.5%, which is a drop of 1 percentage point. In relative terms, that is a fall of about 10.5%. Percentage points measure the gap between two percentages, while percent change measures that gap against the starting value. Numerical questions can ask for either, so check the unit in the question and the answer options before you calculate.
You may see variations on this question, such as the same graph with a different group or year, a combined rate across groups, or a percent change instead of percentage points. In every case, write the formula first (rate = part / total) and only then pull numbers from the graph.
Criteria Corp (CCAT)
Criteria Corp is a US assessment company founded in 2006 and based in Los Angeles. It is best known for the Criteria Cognitive Aptitude Test (CCAT), a pre employment assessment that Criteria says has been administered more than 10 million times.
- Test types - aptitude, personality, and skills tests, including the CCAT, the language-independent UCAT, mechanical reasoning, and game-based assessments.
- Typical clients - organizations of all sizes. Criteria names managerial, software engineering, financial analyst, and auditor roles among those where the CCAT predicts performance well.
- CCAT format - 50 questions in 15 minutes covering math, verbal, and spatial reasoning, with no calculator.
- Scoring - you receive a raw score and a percentile rank. The average test taker answers about 24 questions correctly, and very few finish all 50.
Because the CCAT is built to be hard to finish, speed matters as much as accuracy. Our CCAT practice helps you build both before the real test.
Predictive Index (PI)
Predictive Index (PI) is a US assessment company founded in 1955 by Arnold Daniels. It is as much a workforce tool as a hiring test: employers use it for hiring, team design, and management, so you may take it as a candidate or as a current employee.
- Test types - the PI Behavioral Assessment and the PI Cognitive Assessment. Employers also use a Job Assessment to define what a role requires, which candidates don't take.
- Behavioral Assessment - an untimed checklist of adjectives that measures 4 work drives: dominance, extraversion, patience, and formality.
- Cognitive Assessment - a timed test of 50 numerical, verbal, and abstract reasoning questions, with a 12-minute limit.
- Typical clients - employers across a wide range of industries. PI reports more than 1,000 partners serving clients in 140 countries.
- Scoring - there is no universal pass mark. Employers compare your results with the profile they set for the role.
The 2 PI tests work differently, so it helps to practice both. Our Predictive Index practice covers the cognitive questions and the behavioral format.
Abstract reasoning is 1 of the 3 question types on the PI Cognitive Assessment. You see a sequence of shapes, work out the rule that connects them, and pick the shape that comes next. The difficulty is that several things usually change at once, so looking at the whole picture makes the pattern hard to see.
How to Approach This Question
- Split each shape into parts - treat every color or element as its own track.
- Follow one element across the series - work out how it changes: the direction it moves, how many steps it takes, or whether it alternates between 2 positions.
- Predict where it lands next - then eliminate every option that doesn't match.
- Repeat with the next element - each element you check can remove several options, so stop as soon as 1 remains.
- Watch for overlaps - elements can sit on top of each other and hide a color, so a missing part may still be following its rule.

About the PI Cognitive Assessment
The PI Cognitive Assessment is a timed test of 50 multiple-choice questions in 12 minutes, which works out to under 15 seconds per question. The questions come from 3 categories: verbal, numerical, and abstract reasoning. A test engine draws them from a larger pool, so each candidate receives a different set of questions with equivalent difficulty.
Your score is the number of questions you answer correctly. Employers set a cognitive target for the role and compare your score with it, so there's no universal pass mark. It's common not to finish all 50 questions.
Abstract reasoning questions test whether you can find patterns in non-verbal information, usually shapes and sequences. They need no specialist knowledge. PI uses the assessment to measure how quickly you learn, adapt, and solve problems.
About This Question
This is a next-in-series question. Each shape is built from several parts, such as an inner square and an outer triangle, and each part follows its own rule. Here, the yellow, blue, and black parts each move in a fixed direction at every step, while the turquoise part alternates between 2 positions. All the rules run at the same time, so you need to track them separately.
No single rule usually gives you the answer. In this question, the yellow rule alone cuts the options from 5 to 2, and the turquoise rule settles the last choice. Checking rules one at a time, starting with the easiest to see, is faster than trying to spot the whole pattern at once.
Colors can also overlap. When one part sits on top of another, the hidden color isn't visible in the shape, but it is still moving. A color that seems to have vanished is a signal to check for overlap before you assume the rule has changed.

Your invitation email is the best place to look. It usually names the test or the platform, and the sender or the logo often shows the assessment company behind it. The instructions screen before you start and the job posting can also help, and if you're still unsure, ask the recruiter directly. Keep in mind that employers choose their own tests, and the same assessment company can give different tests for different roles, so a graduate role may use a different test than an entry-level one. Once you know the company, find it in the directory to see what it tests.
Dozens of companies do. The names candidates meet most often include SHL, Criteria, Predictive Index, Hogan, Korn Ferry, Pearson TalentLens, Wonderlic, Caliper, and Aon. Public safety exams come from specialists such as EB Jacobs, I/O Solutions, Stanard & Associates, McCann Associates, and Morris & McDaniel. You can find more in the directory above.
Start with your invitation email. The sender, the logo, and the web address of the testing platform usually name the company. The instructions page before the test often does too. If you can't find it, ask the recruiter. Keep in mind that brand names change after acquisitions, so your invitation may say Aon instead of cut-e, or Mercer Mettl instead of Mettl.
Assessment companies create and score the tests themselves. Pre employment screening companies often handle other checks, such as background and reference checks, and some bundle tests from assessment companies into their service. Employers may also use the terms assessment vendors or HR assessment services for the firms that supply their tests. For you as a candidate, the test itself always comes from the assessment company.
Start by finding out which company and test you've been given, then practice that specific format. Time yourself while you practice, since most ability tests allow only seconds per question. Read the instructions before you begin, and check whether wrong answers are penalized. If they aren't, guess rather than leave a question blank. On personality questionnaires, answer honestly and consistently, because there are no right or wrong answers.
Usually not a fixed one. Your score is typically compared with other applicants or a norm group, or with a target the employer sets for the role. Predictive Index, for example, compares your results with a target the employer defines, and Hogan reports have no pass or fail. A strong score is one that ranks well for that employer and that role.
Yes, and it helps most on ability tests, where speed and familiarity with the question types matter. Practicing shows you the format, the timing, and the kinds of reasoning involved, so you lose less time on test day. Personality questionnaires work differently. There's nothing to memorize, but practice still helps you understand what traits are being measured and how the questions are framed.
It depends on the company and the test. The CCAT has 50 questions in 15 minutes, and the PI Cognitive Assessment has 50 questions in 12 minutes. A Hogan personality inventory takes about 15 to 20 minutes, and the full Prevue Assessment takes 35 minutes. Some employer-customized tests, such as the Berke Assessment, can run from 10 minutes to an hour. Your invitation usually states the expected time.
