JobTestPrep aspires to help job applicants to succeed on their SDG&E pre-employment tests and receive a job they deserve. To achieve this goal, we have compiled sophisticated practice materials designed to enhance your knowledge of mechanics, electronics, and the basic principles of these areas. Our tests closely approximate the official Red Battery assessment and will also strengthen your symbolic reasoning and reading comprehension, considered crucial for understanding instructions and working with machinery. With our PrepPack™, your problem-solving skills will also reach new heights.

The Mechanical Comprehension part of our materials covers a variety of mechanical topics. The test requires you to solve mechanical problems and scenarios, usually formulated in the form of diagrams. Good understanding of mechanical principles is crucial for reading diagrams correctly. You also need to know how to calculate the actual force with which specifies tools work.

The Symbolic Reasoning section of our Technical Test is directed at honing your arithmetical, algebraical, and logical thinking. Unlike other reasoning tests, it couches logical problems not in words but in mathematical signs. To draw appropriate logical conclusions from given statements, you need to know how to manipulate abstract propositions according to mathematical and logical rules.

The Reading Comprehension part of the Red Battery Test offers practice tests that will teach you how, while reading a text, to zero in on important information and make appropriate judgments about described situations.

The Problem-Solving section teaches you to do quick arithmetical calculations using details provided in various narrative scenarios.

SDG&E Technical Test – Red Battery

The Technical Test—Red Battery is offered by SDG&E to job applicants competing for engineering apprenticeships, craft apprenticeships, or technical training. It comprises four tests, measuring candidates' knowledge and intuition of mechanics, reading comprehension, and symbolic and logical reasoning.

Mechanical Comprehension Test:  This testmeasures candidates ability to solve various mechanical scenarios and problems, ranging from kinetic or potential energy to friction, pressure, sound, fluids, gravity, and force. These scenarios and problems are presented in the form of diagrams, followed by related questions. Sometimes, job candidates may be asked to identify a tool with which a certain task can be performed most efficiently. The test's time limit is 20 minutes, during which you must answer as many as 36 questions.

The Symbolic Reasoning Test: This test measures how well you manipulate symbols according to formal mathematical and logical rules. It presents applicants with logical propositions that are expressed not verbally but visually, in the form of mathematical problems. To make valid logical conclusions on the basis of these propositions, you need to identify the logical relationship between given signs and apply to them mathematical rules. It is a multiple-choice test that asks you to select between three alternatives—“True,” “False,” and “Indeterminable.” There are 30 problems in the test, which you are required to solve within five minutes. 

The Reading Comprehension Test estimates your verbal comprehension and reasoning. It consists of 23 questions which you will need to answer within 10 minutes. In this test, you will read several short passages and answer questions about them, selecting answers from several alternatives.  You may find it helpful to scan quickly a list of questions at the bottom of the text so that you automatically pay closer attention to certain pieces of information while you read.

The Problem-Solving Test measures your ability to solve problems narrated in short scenarios by using arithmetic operations. Usually, you will be told about people who either spend money on certain amount of goods or receive money for certain services. Your task will be to calculate how much money the people would either pay or gain in specified circumstances. You will have only 10 minutes to solve 25 problems.


Frequently Asked Questions and Answers

Q: How many questions are there on the Technical Test?

A: The Symbolic Reasoning part of the test has 30 problems. The Reading Comprehension consists of 23 questions; the Problem-Solving section comprises 25 problems. The Mechanical part has 36 questions. There are thus 114 questions altogether on the Technical Test.

Q: What is the passing score for the Technical Test?

A: Your success on the Technical Test—Red Battery is evaluated by so-called percentile score. This score measures your performance relative to other test takers. Thus, if you receive 90% for your Technical test, this does not mean that you have answered 90% of questions correctly. Your score rather means that you did better on the test than 90% of other job candidates.  

Q: How long do I have to wait to retake the Technical Test, if I fail it?

A: The Technical Test helps employers measure job candidates’ technical skills. Every organization has its own examination rules determining how often you can retake the assessment.
