What Is the TVA AIR Test?

The AIR (American Institute of Research) Test is a multiple-choice test given to candidates for electricity-related positions at TVA. The test covers Algebra, Reading comprehension, and Mathematical usage. The test takes 96 minutes to complete and is considered difficult to pass.

The AIR categories are:

1. Algebra- This section requires you to solve algebraic equations by finding the values of variables. Questions include arithmetic processes for finding single variables, functions, and polynomials. 

2. Number series- This section requires you to decipher the logic of number series to find a missing value in the series.

3. Reading Comprehension- This section includes paragraphs for you to read, and then give judgement on the truth values of statements- are they true, false, or indeterminably true/false according to the paragraph?

Here are some sample test questions for you to try:


Sample Question #1

Consider the following table:

9 1
18 2
27 3
36 4
45 5

Which of the following choices represents the same relationship as demonstrated in this table?

  1. Y = 2X + 1
  2. Y is equivalent to the sum of the value X and a constant C, where C equals 3.
  3. X Y
    2 0.222
    3 0.333
    6 0.666
    10 1.111
  4. TVA AIR Test Sample Question
Answer and Explanation

The correct answer is C.

As can be seen from the table, the relationship is Y = X / 9:

1 = 9 / 9
2 = 18 / 9
3 = 27 / 9
4 = 36 / 9
5 = 45 / 9

Answer (A) is incorrect because if Y = 2X + 1, then when X = 9, Y = 19 instead of 1.

Answer (B) is incorrect because if Y = X + 3, then when X = 9, Y = 12 instead of 1.

Answer (D) is incorrect because in the given table, X is always greater than Y, and in the graph, Y is always greater than X.

Only answer (C) represents the same relationship:

2/9 = 0.222

3/9 = 0.333

6/9 = 0.666

10/9 = 1.111

Therefore, the correct answer is C.


Sample Question #2


Find the missing number on the right:

144 | 73 | 18 | 10 | 520 | ?

  1. 76
  2. 146
  3. 247
  4. 261
Correct Answer
Incorrect Answer

The correct answer is 261.

Every two terms are a pair. The first number is divided by two and then increased by 1 in order to produce the second term.

144/2+1 = 73
18/2+1 = 10
250/2+1 = 261

Therefore, the correct answer is D.


Sample Question #3


Read the passage below and answer the question:

Last year, road fatalities decreased by 9%. According to the latest figures published by the Department of Transportation today, this year has seen the lowest number of deaths in road traffic since records began. However, road deaths are only the tip of the iceberg, because for every death on US roads there are 10 serious injuries such as damage to the brain or spinal cord. Country by country statistics shows that the number of road deaths per year still varies greatly across the US with the countries reporting the lowest number of fatalities being California, Oregon, Washington, Vermont, and Maine, with only 30 deaths per million inhabitants. Vulnerable road users such as pedestrians, cyclists, motorcyclists, and users in certain age groups, notably the elderly, are particularly affected by serious road injuries.

Which of the following statements is correct?

A. Cyclists should be banned from riding on the roads.
B. More animals are killed by cars than by pedestrians.
C. Road deaths are on the rise in Vermont.
D. There are more serious injuries than deaths.
Correct Answer
Incorrect Answer

The correct answer is D.

This is what the text states: "for every death... there are 10 serious injuries".

It follows that there are more serious injuries than deaths.
