EEI TECH Test Practice & Study Guide [2026]

Updated: October, 2026

 

The TECH test, officially the Technician Occupations Selection System (5107), is a pre-employment assessment developed by the Edison Electric Institute (EEI). Investor-owned electric utilities such as FirstEnergy and Southern Company use it to screen candidates for technician roles, including control, instrument and controls, chemical, and engineering technicians. The test has four sections: Graphic Problem Solving, Interpreting Diagrams, Mechanical Concepts, and Reasoning from Rules. Since the EEI sets no universal EEI TECH test passing score, each utility sets its own minimum requirement.

JobTestPrep offers free EEI TECH test practice questions across all four sections, plus two full-length simulations that mirror the real exam's structure and timing. Beyond the free questions, our complete TECH test practice library includes a full study guide, 25+ additional drills, and detailed, step-by-step explanations for every question, so you're not just memorizing answers, you're building the speed and reasoning the real test requires.

What Is the EEI TECH Test (Technician Occupations Selection System)?

The TECH test is built around the work technicians actually do. EEI developed it through a research study, conducted by HR Strategies with 23 investor-owned electric companies, that started with a detailed analysis of technician jobs. A draft battery was given to more than 2,100 working technicians, and a validation study turned the results into the final four-test system. It measures how well you use graphs and diagrams, apply mechanical principles, and follow written rules, which are skills technician roles in the electric power industry rely on.

The EEI TECH test is challenging because it combines four different question types under strict time limits, so it's not enough to know the principles, you need to apply them fast enough to get through every question. TECH test practice is the key to building that speed. Below, we break down each of the four sections with EEI TECH test practice questions and explanations, so you know exactly what to expect before test day.

What Are the Sections of the EEI TECH Test?

Graphic Problem Solving

This section measures your ability to use numerical information presented in graphs and illustrations to solve practical arithmetic problems. Expect to read values from a graph, then calculate with them, for example by dividing one value by another to compare two quantities.

Interpreting Diagrams

This section measures your ability to use symbols and codes to locate objects on a map or diagram and to determine each object's status. You read the legend first, then answer questions that ask you to find and count items, such as the high-voltage poles in the map sections a drainage canal passes through.

Mechanical Concepts

This section measures your ability to understand mechanical principles. Each question shows a picture of a mechanical situation, such as pressurized air entering a cylinder or a beam lifted by a cable, and asks you to choose among three answers. The principles include centrifugal force, gears, gravity, levers, pulleys, and shapes.

Reasoning from Rules

This section measures your ability to read and apply written rules to make decisions and to troubleshoot a logic network. You get a set of rules and a situation, then choose the action the rules require, using only the rules provided and not your own experience.

EEI TECH Test Practice Questions

Section 1 - Mechanical Concepts

The Mechanical Concepts section tests your understanding of mechanical principles. According to EEI, it has 44 multiple-choice questions with a 20-minute time limit, and each question pairs a picture of a mechanical situation with three possible answers. The principles include:

  • Centrifugal Force
  • Gears
  • Gravity
  • Levers
  • Pulleys
  • Shapes

The sample question below shows how these principles appear in the test.

Mechanical Concepts Sample Question

In which direction is more pressure applied on the ice cube? (If equal, mark C.)

Wrong

Wrong

Correct!

View Explanation

The correct answer is C.

Explanation
Hydrostatic pressure (the pressure of standing water) is equal in all directions, not only downwards. Therefore, the ice cube is pressed in equal force from all sides.

Section 2 - Graphic Problem Solving

This test examines your ability to solve practical arithmetic problems based on information presented in graphs and illustrations. The test includes graphs and illustrations, each followed by several questions. Your task is to choose the best answer of the four options.

Graphic Problem Solving Sample Question

The compression factor of helium under 2 psi is approximately ______ the compression factor of air at the same pressure.

Correct!

Wrong

Wrong

Wrong

View Explanation

The correct answer is A.

The compression factor of helium under 2 psi is approximately 0.3.
The compression factor of air under 2 psi is approximately 0.6.
0.3 / 0.6 = 0.5

Section 3 - Interpreting Diagrams

This test examines your ability to use symbols and codes to locate objects on a diagram or map and to determine the objects’ status. You will be presented with a diagram/map followed by several questions. In each question, you need to choose the best answer of the four options.

Carefully read the legend assigned to the diagram/map before answering the questions

Interpreting Diagrams Sample Question

How many high-voltage electricity poles are there in sections through which the drainage canal passes?

Wrong

Wrong

Correct!

Wrong

View Explanation

The correct answer is C.

To solve this question, it will be best to look for each element separately. First, we will write down the sections in which the sewage line passes (A1, B1, C1, D1, C3, D3). Then, we will count the high-voltage electricity pole in each section and sum the result.

A1 = 3, B1 = 2, C1 = 8, D1 = 0, C3 = 0, D3 = 0.

Total = 3 + 2 + 8 = 13.

Section 4 - Reasoning from Rules

This test examines your ability to read and understand rules and to apply them to make decisions. You will be presented with sets of rules and situations, each followed by several questions. Carefully go over the rules and use them to choose the correct answer from the four options.

Make sure not to draw on previous knowledge or experience and only use the rules presented in the test.

Reasoning from Rules Sample Question

You are responsible for a clean room for running chemical tests. The following is the standard protocol in case of contamination.

1. If the contaminating chemical is not listed in the HCL-2017 list, contact a lab technician to run the NHC50P test:
1.1  If the NHC50P test result is below 50%, contact the shift manager, cease work for one hour, and request a cleaning crew. Record the incident in the safety log.
1.2  If the NHC50P test result is above 50%, contact the head scientist, cease work for three hours, and request a cleaning crew. Record the incident in the safety log.

2. If the contaminating chemical is listed in the HCL-2017 list:
2.1 If the chemical has an STR ranking of 4 and below, contact the shift manager and then begin extensive cleaning protocol. Record the incident in the safety log and the company's QA log.
2.2. If the chemical has an STR ranking of 5 and above, initiate immediate lockdown before contacting the shift manager and head scientist. Record the incident in the safety log and the company's QA log and open an SI report.

3. If the contaminating chemical is a neutral substance, defined as water, oxygen, or hydrogen, contact the shift manager, cease work for 30 minutes, and ask for a cleaning crew.

4. The following is the only exception to the above rules:
Declare emergency when:
1. The contaminating chemical is from an external source, OR
2. There is more than one contaminating chemical, OR
3. The contaminating chemical was recorded in the safety log in the last 24 hours.

In case of emergency, act as in case of a contaminating chemical with an STR rating of 5 and above.


A single contaminating chemical from an internal source was found. The first thing you should do is:

Wrong

Correct!

Wrong

Wrong

View Explanation

The correct answer is B.

The first thing you should do when discovering a contaminating chemical is to decide whether it is an emergency. There are three cases of emergency:
1.The contaminating chemical is from an external source, OR
2.There is more than one contaminating chemical, OR
3.The contaminating chemical was recorded in the safety log in the last 24 hours.

Since the text explicitly states the two first cases are not applicable, the only one left to check is case 3, which requires looking in the safety log.

TECH Test FAQs

The EEI TECH test is challenging mainly because of time pressure, not just content difficulty. Mechanical Concepts alone gives you 44 questions in 20 minutes, under 30 seconds per question, and each of the four sections runs on its own separate clock, so time lost in one section can't be made up in another. Since the EEI sets no universal passing score, how "hard" the test feels also depends on the minimum requirement of the specific utility you're applying to, but consistent, timed practice across all four sections is the most reliable way to improve your result.

There is no publicly available pass rate for the Edison Electric Institute TECH test. EEI does not publish aggregate results, and individual utility companies do not typically disclose what percentage of candidates achieve a passing score. What is known is that the test is challenging - particularly the Mechanical Concepts section, which requires answering 44 questions in 20 minutes - and that utilities use the 1-10 index score as a competitive filter, not just a pass/fail threshold. Candidates who prepare with realistic EEI TECH test practice questions and timed simulations consistently report feeling more confident and better-paced on exam day.

The Edison Electric Institute TECH test is used by investor-owned electric utilities across the United States for technical occupation hiring. Confirmed users include CenterPoint Energy, FirstEnergy, Pacific Gas and Electric (PG&E), and DTE Energy, among other regional utilities. The test is typically required for roles such as instrument and controls technicians and other technical positions that demand applied mechanical reasoning, diagram interpretation, and rules-based decision-making. The specific positions and hiring processes vary by employer - check the careers page of the utility you are applying to for confirmation.

EEI scores each of the four sections by the number of questions you answer correctly, with no penalty for guessing, and combines the results into a single index score. EEI doesn't publish a universal passing score. Each utility sets its own requirement, and some, such as DTE Energy, ask for a “Recommended” result on the TECH test.

Score sharing also depends on the employer. Southern Company says it may transfer a score you earned with another utility, and Southern California Edison says candidates who previously passed may not need to retest. Because policies vary, don't count on a score carrying over, and prepare as if every application starts from scratch.

The Technician Occupations Selection System - also known as the EEI TECH test or the 5107 Test - is a pre-employment cognitive assessment developed and owned by the Edison Electric Institute (EEI). It is used by U.S. investor-owned electric utilities to evaluate candidates for technical occupations including instrument and controls technicians and other skilled technical roles at power generation and distribution facilities. The test consists of just over 80 questions across four sections: Graphic Problem Solving, Interpreting Diagrams, Mechanical Concepts, and Reasoning from Rules. Total testing time is approximately one hour.

The Graphic Problem Solving section of the EEI TECH test evaluates your ability to extract numerical information from illustrations and graphs and use it to solve practical arithmetic problems. It is one of the four sections of the TECH battery and consists of 21 questions to be completed in 19 minutes. A graphic problem solving practice test replicates this format - presenting technical illustrations followed by timed multiple-choice questions - so that candidates can build speed and accuracy before exam day. This section is distinct from the Mechanical Concepts section and requires a different skill set: less about physical principles, more about reading visual data quickly and calculating correctly under time pressure.

A static PDF (free or paid) gives you exposure to question formats but cannot replicate the conditions that determine your actual EEI TECH test practice performance. The TECH test is timed - 44 Mechanical Concepts questions in 20 minutes means less than 30 seconds per question. A PDF cannot enforce time limits, track your accuracy by section, or show you where you are losing time. JobTestPrep's EEI TECH test practice questions are delivered in a live simulation environment that mirrors the real test structure across all four sections, gives you section-by-section performance feedback, and provides step-by-step explanations for every question. The goal is not just familiarity with the content - it is building the speed and decision-making reflexes the test actually demands.
