EEI TECH Test Practice Questions & Study Guide [2026]

The EEI TECH test, officially the Technician Occupations Selection System (also known as the EEI TECH Test 5107), is a pre-employment assessment developed by the Edison Electric Institute (EEI) and used by investor-owned electric utilities, including FirstEnergy, to screen candidates for instrument and controls technicians and other technical occupations. The exam includes just over 80 questions across four sections, Graphic Problem Solving, Interpreting Diagrams, Mechanical Concepts, and Reasoning from Rules, completed in about one hour. Since the EEI sets no universal EEI TECH test passing score, each utility sets its own minimum requirement.

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.

EEI TECH Test Practice Questions

In this EEI TECH test assessment, you are tested on your understanding of mechanical concepts and principles. These principles include:

Centrifugal Force
Gears
Gravity
Levers
Pulleys
Shapes

Mechanical Concepts Sample Question

eei tech test mechanical reasoning question ice cube

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

C - the same

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.

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.

A. Half

B. Third

C. Double

D. Equal to

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

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

A. 11

B. 12

C. 13

E. 14

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.

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:

Call the head scientist

Check the safety log

Initiate immediate lockdown

Check if the chemical is in the HCL-2017 list

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.

A proven platform founded in 1992 that has helped thousands of candidates prepare for and pass their assessments at FirstEnergy and other investor-owned electric utilities across the United States.

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.

Your EEI TECH test passing score is reported as an index score on a scale of 1 to 10, calculated by combining the results across all four sections. Scoring is done both by machine and by hand. Most utilities expect a score of 8 or 9 to advance in the hiring process, though the exact threshold varies by employer. As for score sharing - EEI test scores are generally not transferable between utility companies. Each employer administers and evaluates results independently, which means applying to a second utility typically requires sitting the Edison Electric Institute TECH test again from scratch. This makes thorough preparation before your first attempt especially important.

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.

After completing your payment, you will receive two emails: a payment receipt and a login link with your account details. Once you log in and reset your password, you will have instant, unlimited access to your PrepPack.
