CAST Test: Practice Questions and Construction Aptitude Guide

We may earn a commission from some links on this page. Recommendations remain editorially independent.

The CAST Test is an Edison Electric Institute (EEI) employment-test battery used in many electric-utility selection processes for construction and skilled-trade roles. Its official name is the Construction and Skilled Trades Selection System. EEI associates CAST with three broad job areas: transmission and distribution, facilities and equipment, and meter-reader service and repair.

EEI develops and supplies employment tests to participating energy companies. EEI does not administer CAST directly to individual applicants. The hiring utility controls scheduling, delivery method, cutoff standards, retesting, result communication, score-transfer decisions, and accommodations. Traditional third-party descriptions commonly identify Graphic Arithmetic, Mathematical Usage, Mechanical Concepts, and Reading Comprehension. Some resources also describe a revised CAST-R variant. The exact title and sections in your invitation control. JobTestPrep sells third-party CAST preparation. JobTestPrep is not EEI, a utility, an employer, or the official administrator.

The 45 questions on this page are original study exercises. They are not official EEI, CAST, CAST-R, utility-company, employer, testing-center, or JobTestPrep questions and do not reproduce a proprietary test form, scoring system, diagram, conversion table, or passage.

What Is the EEI CAST Test?

CAST stands for Construction and Skilled Trades Selection System. It is an EEI employment-selection battery for construction and skilled-trade occupations in the electric utility industry. It is an aptitude-style selection tool used in hiring processes, not a trade-license exam, energized-work qualification, or lineworker certification program.

Who Uses CAST?

Current EEI Employment Test Batteries documentation associates CAST with construction and skilled-trade jobs across:

• transmission and distribution;
• facilities and equipment;
• meter-reader service and repair.

Not every lineworker, electrician, meter technician, or skilled-trade applicant takes CAST. Employer use varies.

Utility examples:

• Entergy’s public pre-employment testing page lists Construction and Skilled Trades Selection System (CAST) among its EEI batteries.
• CenterPoint Energy’s pre-employment assessments page lists Construction and Skilled Trade Selection (CAST) among EEI assessments it partners on, with employer-provided EEI practice materials.

Always confirm the assigned battery name in your invitation.

Does EEI Administer the Test?

No. Current EEI Industry Training and Testing guidance states that EEI supplies tests to participating member companies and does not administer tests directly to applicants. Applicants deal with the hiring electric company. EEI does not provide results directly to applicants. Candidates who previously completed an EEI test should notify the new hiring company.

CAST Test Quick Facts

Intended job family	Construction and skilled trades in transmission/distribution, facilities/equipment, and meter-reader service and repair
Assigned version	CAST or a utility-named variant such as CAST-R - verify in the invitation
Common sections (traditional description)	Graphic Arithmetic; Mathematical Usage; Mechanical Concepts; Reading Comprehension - commonly described by JobTestPrep and many candidate resources
Question count	110 total questions is commonly described by JobTestPrep and other secondary sources; not treated here as a fixed public EEI consumer specification; follow your invitation
Timing	About 90 minutes is commonly described by JobTestPrep; section clocks, check-in, and breaks are utility-specific
Delivery method	EEI states most EEI tests can have multiple delivery options such as paper, computer, and testing center
Calculator rule	Utility-specific; do not treat JobTestPrep’s calculator ban as a universal EEI public rule
Scoring	Index-scale claims such as 1 to 10 are described by JobTestPrep; employer cutoffs vary; not a verified universal public EEI candidate cutoff
Result reporting	Utility-specific
Retest policy	Utility-specific (see Entergy example below)

What Sections Are on CAST?

Traditional CAST descriptions identify four aptitude sections:

1. Graphic Arithmetic
2. Mathematical Usage
3. Mechanical Concepts
4. Reading Comprehension

Do not assume every current administration contains all four traditional sections until your invitation confirms them. CAST-R may differ.

Graphic Arithmetic

This area may ask you to read a drawing, use dimensions, find a missing length, compute perimeter or area, and ignore irrelevant markings when they are not needed.

Mathematical Usage

Transferable skills include whole-number arithmetic, fractions, decimals, percentages, ratios, basic algebra, unit conversion, area, perimeter, volume, and substituting into a supplied formula. Use only formulas or conversions provided in the live materials.

Mechanical Concepts

Useful general themes include force, motion, levers, pulleys, gears, belts, friction, gravity, pressure, heat, and simple circuit continuity. This is aptitude reasoning, not linework or equipment-repair instruction.

Reading Comprehension

Useful skills include locating stated facts, main idea, vocabulary in context, sequence, cause and effect, and distinguishing supported conclusions from unsupported assumptions.

How Many Questions Are on CAST?

JobTestPrep and similar resources currently describe a traditional CAST battery with 110 questions. Current EEI public overview pages emphasize job-family purpose and administration rules rather than publishing that item count as a fixed consumer-facing specification. Treat 110 as a common third-party description unless your invitation or employer brochure states otherwise.

Do not confuse JobTestPrep’s 98-question full-length practice simulation with an official live-test total. That 98-question resource is a third-party product design.

How Long Is CAST?

JobTestPrep commonly describes about 90 minutes of testing time. Instruction, check-in, breaks, and employer logistics can change appointment length. Do not treat unofficial practice timers on this page as official CAST clocks.

Is CAST Paper-Based or Computer-Based?

EEI currently states that most of its employment tests can have multiple delivery options, including paper, computer, and testing center. Computer delivery does not necessarily mean remote or unproctored testing. Your hiring utility’s invitation controls the actual method.

Can You Use a Calculator?

Calculator policy is utility-specific. JobTestPrep states calculators are not permitted, but that statement is not treated here as a verified universal EEI public rule. Follow the invitation and proctor instructions. Do not use unauthorized devices.

Can You Use Scratch Paper?

Scratch-paper rules are utility-specific or session-specific. Do not assume. Follow the invitation and proctor instructions.

Are Wrong Answers Penalized?

Follow the live instructions for your assigned form. Do not rely on a universal guessing strategy based only on third-party claims.

How Is CAST Scored?

EEI public materials emphasize that hiring companies handle applicant results. JobTestPrep describes an EEI index scale from 1 to 10 and employer thresholds such as 4, 5, or 6. Those cutoff examples are not published here as universal official EEI rules for every utility and role. Employers can set their own standards. Candidates may or may not receive a numeric index score.

What Score Do You Need?

There is no universal public candidate cutoff that should be assumed for every utility and vacancy. Practice scores do not predict employer decisions, interviews, apprenticeships, or offers.

Can CAST Scores Be Transferred?

Prior EEI testing may sometimes be considered by another company, but transfer is not automatic. Notify the new hiring utility and follow its authorization process. Entergy, for example, currently directs candidates who previously passed the required test elsewhere to complete an EEI Authorization to Release form and return it to Entergy’s candidate-testing contact. The receiving company decides whether a retest is required.

What Is the CAST Retest Policy?

Waiting periods and attempt limits are utility-specific. Do not publish 30 days or two attempts per year as universal CAST rules.

Entergy example only: Entergy currently states that a minimum of 30 days must pass between the first and second attempt on the same EEI test, and that applicants may not take the same test more than twice in a twelve-month period. Other utilities may differ.

What Is CAST-R?

Third-party preparation resources, including JobTestPrep, describe CAST-R as a revised CAST variant. Public EEI overview pages emphasize CAST job-family purpose and do not provide a detailed consumer-facing CAST-R specification in the same overview materials checked for this guide. When your invitation names CAST-R, follow that invitation for sections, timing, and scoring. Do not assume CAST and CAST-R are identical.

Does CAST-R Include a Behavioral Inventory?

JobTestPrep states that CAST-R replaces Mathematical Usage with a behavioral inventory while keeping other core aptitude areas. That structure is presented here as a third-party description, not as a verified universal EEI public specification. Do not invent scored behavioral-inventory practice. If your form includes behavioral items, follow the live instructions exactly.

CAST vs MASS

Feature	CAST	MASS
Official focus	Construction and skilled trades	Power-plant maintenance positions
Broad EEI contexts	Transmission/distribution; facilities/equipment; meter-related service	Fossil, nuclear, and hydroelectric plant maintenance
Interchangeable?	No	No

For MASS preparation, see the EEI MASS Test guide. For the wider EEI family, you may also review JobTestPrep’s overview of EEI employment tests.

CAST vs POSS

POSS targets plant-operator roles. CAST targets construction and skilled-trade roles. They are not interchangeable. For POSS preparation, see the EEI POSS Test guide.

CAST vs TECH

TECH targets technician occupations that commonly require an associate degree. CAST is a construction and skilled-trades selection battery. For TECH preparation, see the EEI TECH Test guide.

CAST vs IBEW Aptitude Test

IBEW / NECA apprenticeship testing is a separate union apprenticeship pathway. Do not merge IBEW algebra and reading specifications into CAST preparation. See the IBEW Aptitude Test guide when that is the assigned process.

• EEI controls the official battery name and broad job-family purpose.
• The hiring utility controls applicant administration.
• EEI does not administer tests directly to applicants and does not provide applicant results directly.
• Delivery, sections, cutoff, retest, and transfer rules may vary.
• JobTestPrep is not an official EEI source.
• Official URLs must not contain affiliate fragments.

When your invitation covers several skill areas, broader Assessment test preparation can support mixed review before test day.

For ranked-response or work-style sections, numerical reasoning preparation may also be useful when you need extra drills under time pressure.
