TVA Test Preparation Course - Practice for AIR & EEI ({currentTear})
Updated: October, 2026
The TVA AIR Test, officially called the Electrical Training Alliance Aptitude Test, is a timed multiple-choice assessment used by the Tennessee Valley Authority (TVA) to screen candidates for entry-level electrical trade positions. If you meet the minimum qualifications for a posted opening, TVA invites you to sit the test by email.
Key facts about the TVA AIR Test:
- The test covers three areas: Algebra, Reading Comprehension, and Mathematical Usage. It takes 96 minutes to complete and is used for Groundman Trainee, Lineman Apprentice, and Electrician Apprentice positions.
- TVA uses a separate set of tests, the EEI POSS and MASS assessments, for its plant and technician trainee roles (Student Generating Plant Operator, Instrument Mechanic, Electrical Technician, Mechanical Technician, Hydro Technician, and Combustion Turbine Technician).
- Unlike a stand-alone retest system, the AIR test invitation is tied to a specific job posting. If you aren't selected, you'll generally need to apply to a future opening to be invited to test again, rather than booking an individual retake on demand.
- TVA has not published a fixed retake waiting period or validity period for the AIR test the way some other utilities do. Check current guidance from TVA Careers before assuming a past result carries forward to a new application.

What Is the TVA AIR Test?
The TVA AIR Test, officially the Electrical Training Alliance Aptitude Test, is a pre-employment assessment TVA uses to screen applicants for entry-level electrical trade training positions. Candidates who meet the minimum qualifications for a posted opening receive a testing invitation by email. The test is multiple-choice and covers three areas: Algebra, Reading Comprehension, and Mathematical Usage, completed in 96 minutes, with calculators provided. TVA states that these aptitude tests are designed to predict performance in training and on the job, rather than to assess existing trade knowledge.
The AIR Test is used for three positions: Groundman Trainee, Lineman Apprentice, and Electrician Apprentice. Lineman Apprentices assist journeymen linemen in constructing, servicing, and maintaining TVA's 17,000 miles of transmission and distribution lines, a role that requires the physical ability to climb to heights in excess of 500 feet, extensive travel across TVA's seven-state service region, and availability for emergency storm restoration work in all weather conditions. Electrician Apprentices assist journeymen electricians in constructing, servicing, and maintaining TVA substations. Both apprenticeships require a high school diploma or GED and a valid driver's license, and pay progressively increases as apprentices advance through training before moving into the full Lineman or Electrician role.
Apprenticeship openings are posted for a limited window under TVA Careers and typically close within days, after which no further applications are accepted for that opening. Candidates who meet the minimum qualifications are then invited by email to sit the AIR Test. TVA notes that recent hiring cycles for its apprenticeship programs have drawn more than 2,000 applicants, so passing the test is only one step in a competitive selection process.
What are the Sections of AIR?
This section measures your ability to solve algebraic equations and recognize mathematical relationships, including finding the value of a variable, working with functions and polynomials, and identifying when two expressions represent the same underlying relationship.
This section measures your ability to draw a conclusion that is directly supported by a written passage, judging whether a statement is true, false, or impossible to determine based on the text alone.
This section measures your ability to apply a given formula to a practical calculation, such as a unit conversion or measurement problem, rather than testing whether you have formulas memorized.
AIR Practice Test
These three sample questions reflect the three sections of the real TVA AIR Test: Algebra, Reading Comprehension, and Mathematical Usage. Each one includes the question itself and a separate Additional Information tab that explains what that section of the test is designed to measure and how to approach similar questions when you sit the real exam.
Because the real test covers all three sections in a single 96-minute sitting, treat each sample as a quick drill: read the question, choose an answer before checking the explanation, then open the Additional Information tab even if you got it right. The goal at this stage is to recognize the pattern each section tests, not just to confirm one answer.
1. Algebra
Tip:
Test each answer choice against at least two data points from the original table, not just one. A wrong answer can match a single value by coincidence, which is exactly what this type of question is designed to catch you on.
2. Reading Comprehension
Tip:
Read the question before the passage, then scan for the specific fact it's asking about instead of reading the whole passage closely first. You can always look back, so there's no need to memorize it upfront.
3. Mathematical Usage
Please choose the correct answer. If none of the options is the correct answer please choose answer choice e, "N".
Formulas:
- Area of a Rhombus = 1/2(Diagonal1 × Diagonal2)
- Volume of a pyramid = 1/3 × base area × height
- Area of a trapezoid = [1/2(upper base + lower base)] × height
- Degrees Kelvin = degrees Celsius + 273.15
- Degrees Celsius = 100 - degrees Delisle × 2/3
- Surface area of a cuboid = 2 × length + 2 × width + 2 × height
- Mass = weight / gravitational acceleration
- Area of an ellipse = 3.14 × r1 × r2
- Interior angle of a regular polygon = 180(n-2)/n, where n = number of sides
- Length of a circular arc = degrees of the angle × (π/180) × r
The water temperature in Kentucky Lake is around 300.372 degrees Kelvin in June. What is the water temperature in Celsius?
Tip:
Identify which variable the question asks for and rearrange the formula before plugging in any numbers. Doing it the other way around is how sign errors like the ones in this question's wrong answers happen.

The questions above are a sample of what to expect, but TVA's real test gives you about a minute and a half per question, not unlimited time, since all three sections have to fit into a single 96-minute sitting. That kind of pressure is hard to prepare for by reading alone. Our PrepPack™ includes full-length AIR Test simulations timed to match TVA's actual 96-minute limit, so test day is the second time you feel that pace, not the first.

Inside the Prep Course - Preview
We've created a comprehensive TVA AIR Test PrepPack designed to help you succeed. Our PrepPack closely mimics the actual test's timing and format, allowing you to identify and improve your weaker areas. With this focused preparation, you'll be confident and ready to excel on test day.
Why preparation matters: TVA's AIR Test gives you just 96 minutes to complete all three sections (Algebra, Reading Comprehension, and Mathematical Usage), leaving well under two minutes per question across a demanding mix of question types. Our practice simulations run at that same real time limit, and our extra practice is designed to build your speed beyond what the actual test demands, so when test day comes, the real pace feels manageable.
What’s Inside Our AIR Prep Pack
Using our TVA AIR Test PrepPack, you get:
- Complete AIR Test preparation across all three real test sections - 3 full-length AIR practice tests plus 1 AIR diagnostic test, covering Algebra, Reading Comprehension, and Mathematical Usage together in the same mixed format as the real exam. Since TVA also uses a separate EEI POSS/MASS test for plant and technician trainee roles, the PrepPack includes full practice for both tests, so you're covered no matter which one TVA invites you to take.
- Practice built around the AIR Test's real question style - including questions that ask you to recognize the same mathematical relationship across different formats (an equation, a written statement, a table, and a graph, for example). This cross-format reasoning is a recurring feature of the real test, so practicing it specifically matters more than generic algebra drills.
- Detailed explanations for every practice question - not just the correct answer, but the reasoning behind it, so you understand the method, not just the result.
- Study guides and video tutorials covering the EEI tests - including mechanical and electrical comprehension review and spatial reasoning guidance, so you can shore up the related material before you start timed practice.
- Bonus Personality and Situational Judgment practice - a full-length personality test plus 8 Situational Judgment Tests for supervisory and managerial roles. Neither is part of the AIR Test itself, and the SJT content is aimed at supervisory-track roles rather than entry-level apprentice positions, but both are included as additional practice.
- Backed by JobTestPrep's 30+ years of assessment prep experience - developed using official TVA and Electrical Training Alliance testing information.

AIR Test FAQs
The Tennessee Valley Authority (TVA) is the largest public power company in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia, and it provides electricity, manages natural resources, and promotes economic development across the region.
The TVA AIR test, officially the Electrical Training Alliance Aptitude Test, is a multiple-choice assessment TVA uses to screen candidates for the Groundman Trainee, Lineman Apprentice, and Electrician Apprentice positions. It covers Algebra, Reading Comprehension, and Mathematical Usage, and takes 96 minutes to complete.
They're two different tests for two different groups of roles. The AIR test applies to Groundman Trainee, Lineman Apprentice, and Electrician Apprentice positions. The EEI tests (POSS and MASS) apply to plant and technician trainee roles instead, including Student Generating Plant Operator, Instrument Mechanic Trainee, Electrical Technician Trainee, Mechanical Technician Trainee, Hydro Technician Trainee, and Combustion Turbine Technician and Combined Cycle Technician Trainee.
TVA confirms that calculators are provided for its EEI tests (POSS and MASS), but its published testing information doesn't state whether calculators are allowed on the AIR test specifically. If this matters to your preparation, it's worth confirming directly with TVA once you receive your testing invitation.
The AIR test invitation is tied to a specific job posting, not a stand-alone retest system. If you aren't selected, you'll generally need to apply to a future opening to be invited to test again, rather than booking an individual retake on demand. TVA hasn't published a fixed waiting period or validity window for AIR test results.
Our practice materials for the Mathematical Usage section include a provided formula sheet, matching how Mathematical Usage questions typically work on similar EEI-family assessments. TVA's own published testing information doesn't confirm this detail for the AIR test specifically.
