- Here, EMPEA means ExxonMobil Pre-Employment Assessment, an employer hiring screen, not a certification or licence.
- The wage battery has four named components: Mechanical Comprehension, Technical Checking, Use of Industrial Information and Behavioral Tests.
- Not every applicant sees every component, so check your own invitation for the exact list.
- Use of Industrial Information is 40 of the 60 timed minutes, making it the highest-value study area.
Why the Acronym Needs Clarifying
Search for "EMPEA" and you will find a tangle of unrelated results. The letters are shared by several organizations and credentials, and a candidate who lands on the wrong one can waste hours studying the wrong material. This article draws a clear line: when this site says EMPEA, it means the ExxonMobil Pre-Employment Assessment and nothing else.
That distinction matters for practical reasons. The ExxonMobil assessment is an employer's hiring step for operations and maintenance wage positions. It is not a course you enrol in, not an exam you register for through a commercial testing provider, and not something that earns you a credential to hang on a wall. If you are still orienting yourself, our overview What Is the ExxonMobil Assessment? covers the basics, and ExxonMobil Assessment Meaning: Where It Fits in Hiring explains where it sits in the wider recruiting process.
What the Name Actually Refers To
"ExxonMobil Pre-Employment Assessment" is a descriptive label rather than a single test with one fixed form. It describes the set of screening assessments ExxonMobil uses before it makes hiring decisions for certain roles. For Operations and Maintenance wage positions at refineries, chemical plants and terminals, ExxonMobil administers the testing itself rather than outsourcing it to a commercial provider.
Three features of the name are worth understanding:
- "Pre-Employment" signals that this happens before an offer. Passing it moves you forward; it does not hire you.
- "Assessment" is deliberately broad. It is a battery of components, not one paper.
- ExxonMobil as administrator means testing is run internally, at company test centres or online under camera supervision, with no fee charged to the applicant.
For the cost picture in more detail, see ExxonMobil Assessment Costs and Optional Preparation, which separates the free official process from any optional study resources you might choose.
The Four Components and Their Official Names
ExxonMobil publishes its own Operations and Maintenance Testing Preparation Guide, and the wage battery it describes has four named components. Learning these names exactly helps you recognise them in your invitation and search for relevant practice. The official guide is available from ExxonMobil's careers materials: ExxonMobil Wage Test Study Guide.
Mechanical Comprehension Assessment
Measures the ability to apply general mechanical principles to problem situations. It runs 15 minutes and uses four-option multiple choice.
- Expect practical, scenario-style questions rather than abstract theory
- Four answer options per item
- The shortest of the knowledge-based timed components after the checking test
Technical Checking Test
Measures speed and accuracy in applying a rule set shown on an on-screen Command Card. It runs only 5 minutes.
- Deliberately built so most applicants do not finish
- You can still score well without completing every item
- Rewards careful rule-following under time pressure rather than raw volume
Use of Industrial Information Test
Measures the ability to read and use graphs, charts, tables, forms and written passages. It runs 40 minutes.
- Scratch paper is provided
- Calculators are prohibited
- Written so every item can be solved without a calculator
Behavioral Tests
Untimed, with four or five response options and no right answers. They measure Teamwork, Safety Orientation, Learning Orientation and Conscientiousness.
- ExxonMobil warns the dimension being scored is often not the obvious one
- The official advice is to answer honestly rather than strategically

A note on the numbers
Add up the timed components and you reach 60 minutes: 15 for Mechanical Comprehension, 5 for Technical Checking and 40 for Use of Industrial Information. That makes Use of Industrial Information two-thirds of the timed battery, which is why it is the highest-value place to invest preparation time. The untimed Behavioral Tests sit outside that 60-minute total.
Wage Battery vs Graduate and Professional Route
One source of naming confusion is that ExxonMobil does not use a single assessment pathway for every hire. The four-component battery above is the one tied to Operations and Maintenance wage positions. Graduate and professional hiring follows a separate route with its own tests and its own session structure.
This site's scope is the operations and maintenance wage assessment. If you are applying for a graduate or professional role, do not assume the wage battery described here applies to you, and rely on the instructions in your own invitation instead. The table below shows how to separate the two in your mind.
| Feature | Operations and Maintenance wage route | Graduate and professional route |
|---|---|---|
| Typical roles | Wage positions at refineries, chemical plants and terminals | Graduate and professional hires |
| Format | Four named components; not every applicant sees every one | Separate battery with its own session structure |
| Source of detail | ExxonMobil's published Operations and Maintenance Testing Preparation Guide | Your individual invitation |
| Covered by this article | Yes | No |

Reading the Names in Your Invitation
Your invitation is the authoritative source for what you will actually face. Because not every applicant sees every component, two candidates for different wage roles may be tested on different combinations of the four. Do not assume you will meet all of them, and do not skip preparation for one just because a friend did not see it.
When your invitation arrives, check these points and note any that are unclear:
- Which components are listed. Match each to the official names above.
- Where you will test. At a company test centre, or online under camera supervision.
- Any deadline or scheduling window. Treat the invitation as the only reliable source for timing.
- What is permitted. Scratch paper is provided for the Use of Industrial Information Test, and calculators are prohibited.

Why It Is a Hiring Screen, Not a Credential
The word "assessment" is sometimes mistaken for "certification" because both involve passing something. They are very different. A certification is awarded by a certifying body and, once earned, belongs to you across employers. The ExxonMobil Pre-Employment Assessment is a step in one employer's hiring process.
That has several consequences:
- There is no credential to list or maintain, and no renewal process to track.
- A good result does not guarantee an offer; it indicates you met the minimum requirements to continue.
- ExxonMobil publishes no numeric cut score. Applicants are told only whether they met the minimum requirements, and results arrive after a short wait.
Because of this, comparing it with professional certifications leads to the wrong expectations. Our pages Is the ExxonMobil Assessment a Certification? and ExxonMobil Assessment Credentials: Hiring Screen vs Certification unpack this in detail. For how results are communicated and used, see ExxonMobil Assessment Scores: Results and Hiring Decisions and What Does a ExxonMobil Assessment Result Mean?. If you are weighing effort against reward, Is ExxonMobil Assessment Preparation Worth Your Time? frames that decision honestly, and ExxonMobil Pay: How to Evaluate the Role and Offer covers how to assess a role once you reach that stage.
Matching Preparation to Each Named Component
Once the names are clear, preparation becomes a matter of giving each component the attention its weight deserves. Here is one way to sequence study across the named components, assuming your invitation lists all four. Adjust it if yours lists fewer.
Use of Industrial Information Test
- Start here because it carries 40 of the 60 timed minutes
- Practise reading graphs, charts, tables, forms and written passages
- Work on scratch paper only, since calculators are prohibited
Use of Industrial Information, continued
- Time yourself against the 40-minute limit
- Review any item types you found slow or confusing
Mechanical Comprehension Assessment
- Practise applying general mechanical principles to problem situations
- Use the four-option format and the 15-minute limit
Technical Checking Test and Behavioral Tests
- Rehearse rule-following speed and accuracy for the 5-minute checking test, accepting that you may not finish
- Read the Behavioral Tests dimensions and plan to answer honestly rather than strategically
The ordering is deliberate. Use of Industrial Information comes first and gets the most time because of its weight. The Technical Checking Test comes late because it is so short and is built so that finishing is not the goal; accuracy under the Command Card rules matters more than volume. The Behavioral Tests come last in the plan, though not because they matter least: there is nothing to memorise, and ExxonMobil's own advice is honest answering over strategy.
