What are the Main Challenges of the EEI TECH Test ?
EEI tech tests are challenging because they combine four different types of questions and are timed. This means you need to handle many concepts and principles quickly. It's not just about knowing the principles; you also need to answer the questions quickly enough to get through all of them in the allotted time.
Practicing is a key component of this test. To help you understand the different types and to start practicing, let's go over the four sections and see example questions and explanations.
Section 1 - Mechanical Concepts
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 Reasoning Sample Question
In which direction is more pressure applied on the ice cube? (If equal, mark C.)
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.
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?
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:

TECH Test FAQs
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 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 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.
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.
