Can You Cheat the EEI Test? Not on Paper

The EEI batteries are sat in person, on paper, in a room the utility runs, and the result travels with you between utilities.

Short answer: no.

There is no unsupervised stage to game and no fresh start to hide a bad sitting behind: the result is kept and shared.

Where
In person, at a site the utility arranges. Dominion Energy tests on site; FirstEnergy at locations across its service territory.
Format
A paper booklet and a scanned answer sheet for CAST, MASS, POSS and TECH. SO/PD II is on a computer, still in person.
In the room
A test administrator. Southern California Edison bans phones, other electronic equipment and study aids, and you may not leave the room or talk.
Forms
CAST has two alternate forms, POSS two alternate batteries and TECH two versions, in EEI’s own brochures.
Your result
Kept and shared. EEI asks you to tell a new employer about an earlier sitting, and utilities limit how often you can retake.

There is no unsupervised stage to work around

Almost every shortcut people describe for an online assessment assumes you are alone with your own device. The EEI batteries remove both. CAST, MASS, POSS and TECH are pencil and paper tests with an answer sheet read by a scanner, sat in a room with a test administrator. Southern California Edison's candidate guides spell out the room: "you may NOT leave the room, talk, smoke, eat, or drink", phones and other electronic equipment "will NOT be allowed in the testing area", and "No study aids are allowed".

The mechanism that actually defeats it
A supervised paper sitting at the utility's own site, in alternate forms, with a result that follows you. There is no screen to share, no second window and no answer key that matches your booklet.

The paper you get may not be the one anyone described

EEI builds its batteries in more than one form. Its CAST brochure describes "two alternate forms", POSS comes as "two alternate test batteries, which differ slightly in content and administration time", and TECH was developed as "two versions". A remembered question from a forum, even an accurate one, may simply not be on your paper.

Your result follows you between utilities

EEI runs its tests as a consortium of member companies, and results can travel between them. EEI asks anyone who has sat a test elsewhere to tell the company they are applying to, and utilities such as Entergy ask for a release form to bring an earlier result across. Retakes are rationed too: two attempts in twelve months at Entergy and Arkansas Electric Cooperative Corporation, and a 90-day wait at LG&E and KU if your result was the reason you were not selected. A bad sitting is not something you can hide behind a fresh one.

And the utility sets the bar for the job

Each battery is validated for a job family, which is why EEI publishes no universal pass mark: the utility chooses its own cut-off on a combined index. The subtests measure things the work uses every day, reading a safety procedure, judging which way a gear turns, working a dimension off a drawing. A candidate who got past the test without them would meet the same demands in training and on a live system.

What working on it actually looks like

The honest route is short. Nothing is deducted for a wrong answer, so answer everything. Most of the batteries share Mechanical Concepts, and the rest is reading, arithmetic and pattern work that improves quickly with timed practice. Our EEI practice tests give you each subtest on EEI's own clock, starting with Mechanical Concepts for free.

Do
Use the utility’s own link to EEI’s practice tests, which are free.
Answer every question. The score is the number right, with no deduction.
Practise each subtest in your battery on its own clock.
Ask the utility whether a calculator is provided before the day.
Tell a new utility about an earlier sitting, as EEI asks.
Do not
Do not look for leaked EEI answers. CAST, POSS and TECH exist in more than one form.
Do not expect to bring a phone, notes or your own calculator into the room.
Do not book a retest early. Utilities set a minimum wait and cap attempts.
Do not assume every lineworker sits CAST. Some utilities use HireVue instead.

The cost is the job itself

These are hiring tests for work on power plants, substations and energy lines, where honesty about what you can and cannot do is a safety matter. Misconduct in the room ends the application, and because results and attempts are tracked, it can follow you to the next utility too. There is nothing on the other side of that trade worth having.

Frequently asked questions

Can you take an EEI test at home?

Not at the utilities we checked. EEI offers paper, computer and testing-centre delivery, but Dominion Energy says its EEI tests "are administered on-site and scheduled in advance", FirstEnergy tests "at various locations throughout our service territory", and TVA runs a supervised sitting of about three hours. SO/PD II is taken on a computer, but still at a test site.

Can you get the answers to the EEI test?

No. EEI’s practice tests are separate from the real ones, and FirstEnergy notes that "the EEI website does not allow access to actual tests". CAST, POSS and TECH each exist in two forms, so even a real memory of someone else’s paper would not tell you which one you will get.

Can I bring a calculator or notes?

Not your own. Southern California Edison says "No study aids are allowed", and TVA provides a basic four-function calculator for its MASS and POSS sitting rather than letting you bring one. CAST-R permits a calculator on Graphic Arithmetic; ask the utility what it provides.

If it goes badly, can I just sit it again somewhere else?

Not quietly. EEI asks candidates to tell a new employer if they have taken the test elsewhere, and Entergy and Arkansas Electric Cooperative Corporation ask for a release form to transfer an earlier result. Retests are rationed: Entergy and AECC allow two attempts in twelve months, with 30 and 15 days between them, and LG&E and KU make you wait 90 days.

Does a good score last?

At some utilities, yes, which is the honest way to make one sitting count. TVA says "Test results are good forever" and uses your highest score, and Entergy keeps a qualifying result on file for other jobs that need the same test.

EEI practice tests

The Edison Electric Institute (EEI) employment tests US electric utilities use to hire: CAST and CAST-R (Construction and Skilled Trades Selection System, the lineman and lineworker aptitude test), POSS (Plant Operator Selection System, the power plant operator test), MASS (Power Plant Maintenance Positions Selection System), POSS/MASS, TECH (Technician or Technical Occupations Selection System) and SO/PD II (System Operator and Power Dispatcher). Practised here as their subtests: Mechanical Concepts, Reading Comprehension, Mathematical Usage, Graphic Arithmetic, Assembling Objects, Figural Reasoning, Analytic Thinking Skills, Reasoning from Rules and Interpreting Diagrams. Also searched as the EEI test, EEI exam, utility aptitude test, 5108 CAST or 5107 TECH. United States.
