1 INTRODUCTION TO THE GAS JOBS SELECTION TEST BATTERY PSEG 2011 Developed by Human Systems Technology Corporation Columbia, MD CG Selection Test Battery Samples.pdf

2 HUMAN SYSTEMS TECHNOLOGY Page 1 This battery of aptitude tests was designed and validated to aid in the selection of candidates for the Gas job classifications at PSEG. There are seven paper-and-pencil tests in the battery. No prior knowledge of Gas Service job tasks is required. The tests are designed to assess underlying abilities that are necessary to readily learn critical job requirements and perform successfully on the job. The tests in the battery are timed and the entire administration session lasts approximately two hours. The tests measure reading comprehension, attention to detail, logical reasoning, mechanical concepts, and basic math. The aptitude tests comprising the battery with test item examples are provided below. READING COMPREHENSION Test IST Reading Comprehension - This 30-minute test assesses the ability to quickly read, understand, and interpret written material. An example of a passage with two sample questions is given below. The telephone is one of our most important tools in establishing good relations with customers and suppliers. When answering or placing a call, identify yourself as well as the company. Remember that the number of phone lines is limited please exercise common sense in using the telephones for personal business. S1. The use of the company telephone for personal calls is: A. prohibited by the company B. limited to certain phone lines. C. expected to be limited and sensible D. encouraged. S2. Which statement best describes management s view of the telephone? A. It is off limits for personal use. B. It is of limited use in dealing with customers and suppliers C. It is best used for personal business. D. It is useful for creating a positive company image. You should have selected answers C and D.

3 HUMAN SYSTEMS TECHNOLOGY Page 2 ATTENTION TO DETAIL Two tests measure the ability to pay careful visual attention to the details of a job. They include the following: Attention to Detail Test This 5-minute test assesses the ability to see differences in small details in figures. Examinees identify flaws in parts that are supposed to be the same as a referent part. However, some are imperfect. Below are two sample items:

4 HUMAN SYSTEMS TECHNOLOGY Page 3 Visual Speed and Accuracy Test This 5-minute test requires persons to determine similarities or differences in pairs of numbers. It provides an indication of visual discrimination among similar objects. Examples are provided below.

5 HUMAN SYSTEMS TECHNOLOGY Page 4 LOGICAL REASONING - Two tests are used to measure this ability. Scores are combined on these tests to form a composite. Verbal Reasoning Test: measures the ability to identify relationships and arrive at supportable conclusions. Examinees are required to read a set of facts and determine whether certain conclusions are supported by the facts. An example of the Verbal Reasoning test is shown below:

6 HUMAN SYSTEMS TECHNOLOGY Page 5 Numerical Reasoning Test: measures the ability to determine relationships of patterns in a series of numbers. Examinees read series of numbers and identify the next one in a sequence. An example of the Numerical Reasoning test is shown below:

7 HUMAN SYSTEMS TECHNOLOGY Page 6 MECHANICAL CONCEPTS Test IST Mechanical Principles This 20 minute test assesses basic comprehension of mechanical principles of leverage, rotation, momentum, and flow. An example of the Mechanical Principles Test is shown below: You should have selected B and C.

8 HUMAN SYSTEMS TECHNOLOGY Page 7 NUMERICAL COMPUTATION PTI Numerical Test A This 20-minute test requires examinees to fill in the answer to problems requiring addition, subtraction, multiplication, and division; the calculation of percentages, the measurement of length and area; and the manipulation of decimals and fractions.

9 HUMAN SYSTEMS TECHNOLOGY Page 8 ELECTRICAL APTITUDE This 25-minute test assesses the basic ability to understand the concepts underlying electrical principles such as current and resistance, and interpreting diagrams and schematics. No previous electrical knowledge is required. The test is published by Human Systems Technology. SECTION I FLOW EXAMPLE The idea of flow through a closed system is fundamental to understanding how electrical systems function. Water in pipes can be easier to picture in your mind than electricity through wires, so these types of analogies are often used to illustrate the electrical concept of flow. In the figure shown, the movement of energy by flow through the system is the most important concern in your analysis. Keep in mind that you are looking at a closed system. To help you in your analysis, imagine the system is filled with water, with no room for air. The pump generates pressure, creating the flow through the system where the energy is used up in the loads. When thinking of flow, think of water flowing through the system carrying energy. The loads will consume the energy but not the flow. As the energy is used up, the pressure will drop off, but the flow will remain the same. The relative length of the load is proportional to the energy it will use. Flow will only change when divided. Therefore, in the figure shown, the greatest pressure is at point K and is reduced as the energy is used in the loads A and B. The pressure will be least at point J. However, in this system, the flow will remain constant throughout.

10 HUMAN SYSTEMS TECHNOLOGY Page 9 SECTION II WIRING DIAGRAMS EXAMPLE Below are sample wiring diagram questions. You are given a point on the diagram and are asked to find the connecting point (or points). SAMPLE QUESTIONS Example a) In the above diagram, point 3 is directly connected to which of the following points? A. 4 B. 6 C. 1 D. 7 B is the correct response. Example b) In the above diagram, point 1 is interconnected to which of the following points? A. 4 and 5 B. 6 and 3 C. 8 and 9 D. 4 and 9 A is the correct response.

11 HUMAN SYSTEMS TECHNOLOGY Page 10 SECTION III PICTORIAL/SCHEMATIC DIAGRAMS EXAMPLE Below are sample pictorial/schematic diagram questions. You are shown a pictorial diagram and the corresponding schematic diagram. The questions ask you either to look at the pictorial and find the matching point in the schematic or to look at the schematic and find the matching point in the pictorial. SAMPLE QUESTIONS Example a) Part BT1 in the schematic diagram is represented by what item in the pictorial diagram? A. DC Load B. Lamp C. Switch D. 1.5 volt Cell D is the correct response. Example b) The lamp in the pictorial diagram is represented by what item in the schematic diagram? A. BT1 B. S1 C. DS1 D. Not shown C is the correct response.
