The Physical (PTB) Pre-Employment Test
PG&E's Physical (PTB) pre-employment test is a paper and pencil test which consists of two components:
The PTB pre-employment test is required for entry level physical jobs
This component of the PTB pre-employment test is designed to measure ability in addition, subtraction, multiplication, and division of whole numbers, decimals, and fractions. The applicant must add, subtract, multiply, or divide to solve each problem and then select the correct answer from the five choices provided: four numerical alternatives and an "X," which indicates that the correct answer is not listed. The use of calculators will not be permitted.
This exercise is divided into three sections that are separately timed. Part
1 measures proficiency in working with whole numbers. Part 2 measures
proficiency with decimals. Part 3 measures proficiency with fractions.
Applicants are given the following directions and sample problems:
Look at the sample problems below. Each problem is followed by four possible answers and an "X." You are to work each problem and put a heavy black mark in the circle before the correct answer. If the correct answer is not given, make a heavy black mark in the circle before the "X."
Now work the sample problems below. The first one has been answered correctly.
|1. 5 + 5 =||O 8||O 11||O 9||O 12|
|2. 12 - 6||O 5||O 7||O 6||O 8||O X|
|3. 5 x 5 =||O 23||O 24||O 25||O 26||O X|
|4. 30 / 3 =||O 6||O 7||O 9||O 8||O X|
|5. 6 + 7||O 15||O 13||O 14||O 12||O X|
Space visualization refers to the ability to visualize forms in space and to manipulate objects mentally; this ability is a major component of "mechanical ability." The Space Visualization component of the PTB pre-employment test consists of pictures of piles of blocks. The applicant indicates for a specific block how many other blocks in the pile it touches. In order for a block to be considered touching another block, the blocks must touch each other along a flat surface. Five blocks in each pile are labeled with the letters A through E, and applicants are asked to fill in the circles containing the correct number of other blocks each lettered block touches. There is a time limit to complete this section. Applicants are given the following directions and sample problems:
In the piles of blocks shown below, all of the blocks are the same size and shape. Your task is to look at each lettered block and figure out how many other blocks in the pile it touches. For each lettered block, show the number of other blocks it touches by filling in the circle with the correct number at the right of the letter.
