As mentioned, there are four different components of the POSS test. Let’s go through each of them:
In this test, you have 30 minutes to answer 36 multiple choice questions. You are presented with five different passages, and for each passage, you have to answer a number of different questions.
These passages are generally excerpts from power plant operator training and safety manuals.
M-theory
Einstein was the first to set off on the noble search for the "theory of everything". He spent the last decades of his life searching for clues that would enable him to capture all physical aspects of the universe and unify them into one theoretical framework. Since Einstein, many unified field theories have been proposed but none have prevailed. In the past couple of decades a single explanatory framework, called "string theory" (that then evolved into "superstring theory") has started to gain a lot of attention from scientists around the world. Recently, a series of important discoveries has led to a more comprehensive theory called "M-theory".
The "M-theory" is a revised theory that provides a singular theoretical framework, unifying all the different versions of "string theory". The "M-theory" proves itself time and again when tested. In spite of the theory's durability against any attempts do discredit it, the fact remains that many of its issues are still beyond the reach of scientific examinations. Nonetheless, in one stoke, the M-theory has solved many of the embarrassing features of the string theory, such as why we have 5 superstring theories instead of just one.
For the first time physicists are now able to examine what is called the "non-perturbative" region. That is, problems that cannot be solved using mathematical methods for finding an approximate solution and are thus difficult to explore. This breakthrough is due to a powerful tool called "duality", allowing for an easily solved theory to seem equivalent to a more complex theory under a certain interchange so that the non-perturbative region can be solved. Advancements in the unified field were quick to come. Such was the work of Paul Townsend and Edward Witten; they showed that duality exists between 10 dimensional Type IIA strings (previously perceived as am inaccessible region) and 11 dimensional supergravity. The discovery of an 11th dimension was astonishing but also led several scientists to postulate that the final version of the M-theory might not possess a fixed number of dimensions.
Although many enthusiastic string theorists support the M-theory revolution, they are cautious with their future predictions. According to Witten, "we are on the right track, but we need a few more "revolutions" like this to finally solve the theory".

What is mentioned in the passage as a current problem with the M-theory?
Since there are only five different passages, you can spend a little bit of time reading through each one. Taking in the main points slowly, in the beginning helps you overcome the rest of the questions more quickly.
The trick to succeeding in these questions is to practice and understand what you are up against. The more practice you get, the better you will be able to answer the questions. That's why in this PrepPack™, you will find a plethora of different POSS reading comprehension style questions as well as lots of drills to get you up to speed.
In this section of the POSS test, you have 20 minutes to answer 44 multiple-choice questions. There are many different mechanical concepts being tested here, including:
Each question contains a mechanical situation, and it’s your task to select which force is being asked for.
In which of the following positions would the tractor be less stable when taking a turn?
Take a look at this video explaining the basic mechanical concepts to get a better grip on the subject.
If you are applying for lower-level positions, such as a plant operator, you have to take the short version of the mathematical usage test.
Those applying for supervisory roles have to take the longer version.
In the first version, the short version, you have seven minutes to answer 18 questions. This version of the POSS test is actually the same as the mathematical usage test used in the CAST test.
You are provided with a table with a number of different relationships. For example, the number of inches to cm. You have to use this table in order to answer questions based on this information.
Unlike the CAST test, calculators are allowed in this test. However, that doesn’t change the fact that you have less than 30 seconds to answer each question. This is why it’s absolutely imperative to give yourself the practice and preparation that you need in order to succeed on the POSS test.
In this version of the test, you have 17 minutes to answer 46 questions. This test is made up of three sections, including formula conversion problems, algebra problems, and word problems.
Let’s take a look at a sample POSS question:
POSS Math Sample Question Version 2:
X + 14.9 = 7.6
X =?
As you can see, answering these questions takes time. That’s why it’s so important to be prepared for the real thing. Even though you can use a calculator in the test, you only have about 20 seconds to complete each question.
And ensuring you finish the test without having to guess the last bunch of questions really gives you an edge over the other candidates.

There are 10 minutes in which to answer 20 questions for the figural reasoning section of the POSS test. In the test, you have to identify patterns in order to problem solve. There are three different question types in this test; Picture Series, Picture Comparison, and Picture Progression.
Series: You have to know how to complete the series and flow from one image to the next for the series questions.
Comparison: For the comparison ones, you need to compare and contrast two images and then determine what the relationship between them is.
Try to decide where this shape belongs to:
Progression: You are presented with a 3X3 matrix of pictures that form some sort of pattern. One of the nine pictures will be missing.
you are asked to find the correct picture that fit with the matrix pattern:
If you have never seen these questions before, then you will struggle to get the understanding and flow between the different question sets. Moreover, even if you are familiar and think you will have no trouble answering them, can you do so under extreme time pressure? Without practice, in our experience, it’s just impossible. Have a look at some example questions on our abstract and figural reasoning page.
That’s why in the PrepPack™, you will find full explanations giving you the information and style you need. As well as this, you take the questions under timed conditions. Once the clock hits zero, that’s it, you can’t go back, you can’t extend it, and that’s the end.
Our goal is to help you get the best test experience. This goes with the correct styling of the preparation questions along with the correct time limits. Start preparing today to ensure you are fully prepared for the real thing.
Check out our new test preparation system in order to give you the best preparation possible.

Each of the four different tests is graded separately. After this, they are combined to give you an index score that ranges from 0-15. As each company (and there are more than 70 that administer the test) has its own standards, we can’t give you an exact number of what you need to succeed.
However, in our experience, if you score more than 80%, you will be in the top tier.
The reason for this is that most people simply don’t finish the numerical section. It’s really important for you to give yourself the best chance, and if you give yourself enough practice time, you will definitely be able to pass the test.
With our preparation, we are sure you will improve your score as well as your understanding of the concepts you need to succeed. Each question in the PrepPack™ has a full explanation and gives you the understanding you need to conquer any question thrown at you.
It’s important to know which test you need to take. Let’s just lay it out in general terms, though.
POSS: This is the Plant Operator Selection System test and is used for people applying for jobs operating in fossil, nuclear, or hydro power plants
MASS: This is the Power Plant Maintenance Positions Selection System. People applying for the following jobs will be asked to take this test: electrician, helper, instrument and control repairer, insulation worker, machinist, mechanic, painter, pipefitter, rigger, steelworker, and welder. For a complete rundown on that test, see our specialist page.
POSS/MASS: For entry level positions, in order to see where you are best going to progress. For example, if you are more suited to being a plant operator, you will be asked to take the POSS/MASS test. Read more about that particular test below:
The Combined POSS/MASS test is essentially two separate tests that are combined into one. What this means is that you are going to get two separate results. One for the POSS test and another for MASS.
There is an overlap between the two tests, and that’s why they are administered together. Here is a rundown of what overlaps and what is separate. Bear in mind that you have to take the whole lot in one long, three hour sitting:
Test | POSS | MASS |
Reading Comprehension | v | v |
Mechanical Concepts | v | v |
Mathematical Usage Version 1 | v | |
Mathematical Usage Version 2 | v | |
Figural Reasoning | v | v |
As there is such overlap between the two tests, in the PrepPack™ that we offer you, you will gain access to both POSS preparation and to a separate POSS/MASS preparation.
The reason we do so is to ensure that you get the best possible preparation. We don’t want you to run out of time or not understand the questions that you are being asked. Start preparing today with JobTestPrep.
John D. Verified Buyer ⋆⋆⋆⋆⋆Excellent program, took my test and PASSED!! thanks
Although in the past there used to be negative scoring in the test, this is no longer the case. So if you are panicking that you don’t have any time left, you can guess the answers in order to complete the test. However, this isn’t something you should face if you use our test preparation well. You will gain the skills needed to pass the score you need to succeed.
Of course it does depend on the company you are applying to. However, since they are all computerized, most companies will give you your results straight away. You shouldn’t need to wait longer than a few days though.
As there are a number of different tests that make up the POSS exam, your score on the different components of the exam is combined into an index score ranging from 0 to 15.
Whilst the POSS test is administered by multiple companies, they make their own rules about whether you can take the test again. For example, Duke Energy require a 90 day wait. Make sure you are ready for it with this PrepPack™
The Plant Operator Selection System (POSS) test is made up of four different tests. These are reading comprehension, mechanical concepts, mathematical usage, and figural reasoning.
As the test is marked by computer in theory they could give you your result straight away. However, as there is going to be a pool of candidates, the company usually waits until that pool has all taken their tests and only then give you an answer. In general though, you should be able to get your results within a week of taking the tests.
That’s a difficult question to answer. Made up of four different tests, most people don’t even complete the numerical one. The questions are not overly hard but completing everything within the time limit is taxing. That’s why it’s so important to practice for the tests.
In a word – practice tests under timed conditions. There is no shortcut here and the only way to do yourself justice is to get the pack, take some time and get down to work!
