EEI TECH Test: 45 Practice Questions and Study Guide

The TECH Test is an Edison Electric Institute (EEI) employment-test battery. Its official name is the Technician Occupations Selection System. EEI associates TECH with technician jobs that typically require an associate degree. Official EEI examples include laboratory technician, environmental or chemistry technician, distribution planning technician, communications or telecommunications technician, drafter, and estimator.

EEI supplies validated employment tests to participating electric companies. EEI does not administer TECH directly to individual applicants. The hiring utility controls scheduling, administration, delivery method, cutoff standards, retesting, result communication, score-transfer decisions, and accommodations. Public third-party descriptions commonly identify Graphic Problem Solving, Interpreting Diagrams, Mechanical Concepts, and Reasoning from Rules. Different forms or utility configurations may exist, so your invitation and current employer documentation control. JobTestPrep offers third-party TECH preparation. JobTestPrep is not EEI, a utility, a hiring employer, or the official test administrator.

The 45 questions on this page are original study exercises. They are not official EEI, TECH, TECH 5107, utility-company, employer, testing-center, or JobTestPrep questions and do not reproduce a proprietary test form, scoring system, diagram, map, rule set, or answer key.

What Is the EEI TECH Test?

TECH stands for Technician Occupations Selection System. It is an EEI pre-employment selection battery for technician pathways in the electric power industry. It is an aptitude-style hiring assessment, not a professional engineering examination, technician license, electrical license, telecommunications certification, laboratory certification, operator license, or plant-specific technical qualification course.

What Jobs Use TECH?

Current EEI Employment Test Batteries documentation associates TECH with technician jobs that typically require an associate degree and lists examples such as:

• laboratory technician;
• environmental or chemistry technician;
• distribution planning technician;
• communications or telecommunications technician;
• drafter;
• estimator.

These are illustrative official examples rather than a complete list. Not every job title containing “technician” uses TECH. Some employers may use another EEI battery or add interviews, physical stages, background screening, or later credentials. Claims that TECH is used for instrument and controls technicians should be confirmed from current employer materials rather than assumed from third-party lists alone.

Utility naming examples:

• FirstEnergy’s careers practice-test page currently lists Technician Occupations Selection System (TECH) among its EEI practice batteries.
• Entergy’s public pre-employment testing page lists Technical Occupations Selection System (Tech) among its EEI batteries.

Confirm the exact battery name on your invitation.

Does EEI Administer TECH Directly?

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

TECH Test Quick Facts

Detail	Current evidence boundary
Official name	Technician Occupations Selection System (TECH)
Publisher	Edison Electric Institute (EEI)
Job family	Technician roles that typically require an associate degree
Administration	Hiring utility; EEI does not administer its tests directly to applicants
Delivery	EEI says most batteries can have multiple delivery options; follow your invitation
Sections, item count, timing, scoring, calculator, retest	Do not infer one universal candidate rule from commercial preparation material; use current utility documentation

Is TECH the Same as Test 5107?

Some third-party materials, including JobTestPrep, call the battery TECH 5107 or EEI TECH Test 5107. The current EEI Employment Test Batteries overview checked for this guide identifies Technician Occupations Selection System (TECH) and does not present 5107 as a consumer-facing universal name in the extracted public description. Treat 5107 as a form, employer, historical, or third-party label unless your invitation uses that code. This guide does not place 5107 in the title or H1.

What Sections Are on TECH?

Traditional third-party and utility practice descriptions identify four sections:

1. Graphic Problem Solving
2. Interpreting Diagrams
3. Mechanical Concepts
4. Reasoning from Rules

Current EEI public overview materials emphasize job-family purpose rather than publishing a full consumer-facing section table. FirstEnergy lists the TECH battery name on its practice-test page. Do not assume every current form uses identical item counts or clocks without checking your invitation.

Graphic Problem Solving

Useful skills include reading charts and technical illustrations, extracting numbers, comparing series, ratios, differences, percentages, rates, interpreting axes, and solving arithmetic from a visual reference. Practice here uses original accessible tables, not proprietary charts.

Interpreting Diagrams

Useful skills include reading a legend, locating symbols, following a route, identifying zones, counting objects, determining status codes, matching conditions, and ignoring irrelevant symbols. Practice diagrams on this page are fictional campus-style grids only. They are not real utility maps, substation plans, transmission diagrams, or critical-infrastructure layouts.

Mechanical Concepts

Useful introductory aptitude themes include force, motion, gravity, levers, pulleys, gears, belts, friction, pressure, heat transfer, simple circuits, and physical relationships. This is not occupational repair or utility-operation instruction.

Reasoning from Rules

This format may require reading an artificial rule set, applying conditions in order, recognizing exceptions, distinguishing “and” from “or”, and avoiding outside knowledge. Practice rule systems here are harmless fictional office, library, and room-booking rules. They are not emergency, chemical, security, or plant-operation procedures.

How Many Questions Are on TECH?

The current public EEI overview checked for this guide does not publish a universal consumer-facing TECH item total. A commercial simulation count is not an official live-test count. Follow your invitation or utility candidate guide.

How Long Is TECH?

Use the appointment and section timing supplied by the hiring utility. This guide does not publish a partial or commercial timing table as a universal EEI rule.

Are the Sections Timed Separately?

Follow the live instructions supplied by the utility. The public EEI overview checked for this guide does not establish one consumer-facing section-timing model for every TECH administration.

Is TECH Paper-Based or Computer-Based?

EEI currently states that most EEI tests can have multiple delivery options, including paper, computer, and testing center. Computer-based testing at a utility or testing center is not the same as remote unproctored self-administration. You cannot register independently with EEI for a public TECH sitting. Your hiring utility controls the method.

Can You Register Directly With EEI?

No. Candidates receive TECH through a hiring utility or authorized employer process.

Can You Use a Calculator?

Calculator policy is utility-specific. Do not bring or use an unauthorized device. Confirm whether a calculator is supplied, banned, or restricted using your invitation and proctor instructions.

Can You Use Scratch Paper or Reference Materials?

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

Are Wrong Answers Penalized?

Some candidate materials for EEI batteries describe no penalty for incorrect answers, but this guide does not convert that into a universal guessing strategy for every current TECH form. Follow the live instructions for your assigned administration.

How Is TECH Scored?

EEI states that hiring companies handle applicant testing and results. This guide does not publish a universal numeric TECH index, percentile, or cutoff from a commercial preparation source. Follow the utility’s score communication and selection policy.

What Score Do You Need?

There is no universal public cutoff that should be assumed for every utility and vacancy. JobTestPrep’s claim that most utilities expect an 8 or 9 is not treated here as independently verified national EEI policy. Practice scores do not predict advancement, interviews, credentials, or offers.

Will You Receive Your Exact Score?

EEI does not provide results directly to applicants. The hiring utility controls whether you receive a numeric score, index language, or only progression / non-progression messaging.

Can TECH 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. JobTestPrep’s broader claim that scores are generally not transferable should be read as a caution, not as proof that no employer ever reviews a prior EEI result. The receiving company decides.

What Is the TECH Retest Policy?

Retest rules are utility-specific. Do not generalize one employer’s waiting period or annual attempt limit to every TECH administration. Use the current hiring company’s instructions.

TECH vs MASS

Feature	TECH	MASS
Official focus	Technician occupations typically requiring an associate degree	Power-plant maintenance positions
Example roles (EEI)	Laboratory, environmental/chemistry, distribution planning, communications/telecom, drafter, estimator	Mechanic, machinist, electrician, welder, pipe fitter
Interchangeable?	No	No

See the EEI MASS Test guide.

TECH vs CAST

CAST targets construction and skilled-trade utility families. TECH targets technician selection. See the EEI CAST Test guide.

TECH vs POSS

POSS targets plant-operator positions. TECH targets technician occupations rather than operator selection generally. See the EEI POSS Test guide.

TECH vs SO/PDII

SO/PDII targets energy-control-center roles such as system operator, system controller, and power dispatcher. A dispatcher invitation is not automatically a TECH invitation.

For the wider EEI family, you may also review JobTestPrep’s overview of EEI employment tests.

TECH vs Generic Mechanical Aptitude

Mechanical Concepts is only one part of the commonly described TECH battery. Graphic problem solving, diagram interpretation, and rule application also need practice.

Common Mistakes

• confusing TECH with MASS;
• confusing TECH with CAST;
• confusing TECH with POSS;
• confusing TECH with SO/PDII;
• treating TECH as a generic mechanical test;
• assuming every technician position uses TECH;
• treating JobTestPrep as the official source;
• assuming 5107 is a universal current form code;
• assuming every live form contains exactly 83 questions;
• assuming every administration lasts exactly one hour;

Free Versus Paid Preparation

Use the original free practice on this page after confirming TECH in your invitation. If you buy additional third-party preparation, check the current product content, price and access terms directly.
