Review of the TEAS V
A career choice to become a registered or practical nurse may be right for you. Nursing
professionals are consistently listed as one of the most respected and trusted professions in the
country. And, importantly, job security is rarely an issue for a nurse. In most areas of the
country, there are reports of nursing shortages. To become a nurse, one must go to nursing
school and pass a professional exam. Many nursing schools require their applicants to take the
Test of Essential Academic Skills (TEAS), version V. This review discusses the requirements of
the TEAS V.
Education for initial licensure as a registered nurse is provided through diploma
programs, such as community/or junior colleges offering an associate degree in nursing (ADN)
and colleges offering a bachelors degree in nursing (BSN). Most colleges require students who
apply for admission to registered nursing, practical nursing and dental hygiene programs to
participate in pre-admission testing prior to the admissions deadline for the respective
program.
The TEAS is an aptitude test. It is a four-part assessment developed by Assessment
Technologies Institute LLC (ATI). It includes reading comprehension, mathematics, science and
English exam sections. The exam is calibrated to the 10th grade - 12th grade level. Nursing
programs use the TEAS as a tool to evaluate the academic readiness of candidates prior to
admission into the nursing program. Test results are used in admission determinations. The
exam assesses the candidate’s ability to respond and apply knowledge to new situations and to

understand complex technical material and relationships. The results also provide
documentation useful for counseling and advisement.
Some nursing schools also use the TEAS as a placement exam. The exam can identify
students who struggle in certain areas but have the potential to be excellent nurses. Students
can receive remediation in their weak areas to improve their skill level and increase the chance
of success in nursing school.
1. Exam Background and Scoring
The TEAS consists of a total of 170 multiple choice questions and approximately 3 ½
hours is given to complete the test. The TEAS is administered in either a computer based format
or a paper and pencil based format. The TEAS is not a pass or fail test. Students completing the
TEAS exam are encouraged to earn a proficient score or higher in the ATI Academic
Preparedness Category if applying to nursing. Each school has their own cut off scores. The
TEAS score report does not indicate whether a candidate has passed or failed the exam. That
means there is no passing score determined by ATI. Nursing schools have their individual cutoff
scores for admission purposes and to maintain their standards. You will have to check with the
nursing schools to find out their cutoff score.
The TEAS score report gives a detailed description of a test-takes performance on the
test. The following scores are given in ATI’s TEAS score report:
1. Adjusted Individual Score
2. National mean
3. Program mean
TOP Digitally Monitored for Compliance to License Terms © 2013-2014 Tests.com
3
4. Percentile rank – National
5. Percentile rank – Program
The scores for all the content areas of the four test sections are also given. Hence, the score
report of TEAS is extremely descriptive. It gives nursing schools a chance to view your overall
performance in relation to others.
Whether a certain score is sufficient varies from one nursing school to another. As
stated above, nursing schools set their own cutoff TEAS scores for admissions. Most schools
have their cutoffs set around 70% for English, math and science and around 80% for reading
comprehension. However, the weight given to each subject score can vary for each nursing
school.
Some nursing schools lay more emphasis on the national percentiles while others give
more weight to the scores in science and math. The TEAS score report makes it possible to
judge the applicant from various angles. Nursing schools may not publically disclose how they
weigh the scores. Therefore, it is essential to score well in all sections of the test.
2. Exam Content
The TEAS has four sections: English, math, science and reading comprehension. Each
section will be discussed in some detail.
English and Language Usage
The English sub-test measures knowledge of grammar, sentence structure, punctuation,
contextual words and spelling. The time given to take this section is 34 minutes. It has a total of
55 testing items.
TOP Digitally Monitored for Compliance to License Terms © 2013-2014 Tests.com

It is imperative to test the language skills of students since it is the most common
medium of exchange of ideas not only in education but also in your profession. In order to
succeed in the coursework it is most essential to understand the language in which the
instruction is carried out. Moreover, the study and the profession involve a great amount of
interaction among many people. A good understanding of grammar and proper usage of English
makes the journey smoother since it facilitates understanding and results in effective
communication. The English section is essential to judge the basic communication skills of
candidates aspiring to undertake nursing studies.
Mathematics
The math sub-test covers whole numbers, metric conversions, fractions and decimals,
algebraic equations, percentages and ratio/proportions. This section of TEAS has 45 testing
items that need to be answered in 51 minutes. You will get a little more than a minute to
answer each question.
These questions test the basic mathematical skills possessed by students. It is essential
to evaluate these skills since the work of nurses involves the use of math and requires precision
and accuracy. The math problems on the test do not involve difficult concepts; instead only
basic knowledge is required. The use of calculators is prohibited in this section since the
emphasis is on mental activity. Moreover, the questions are such that can be solved with simple
mental calculations or with some scratch work.

Science
The science portion of the exam covers science reasoning, science knowledge, biology,
chemistry, anatomy and physiology, basic physical principles and general science. There are 30
science testing items asked and the 66 minutes are given to complete the test.
Candidates are required to have a basic knowledge in science since many of the courses
a nursing student will face involve science. The profession of nursing involves study of such
subjects as well as keeping in touch with the latest developments in the field.
Reading Comprehension
The reading comprehension sub-test covers paragraph comprehension, passage
comprehension and inferences and conclusions. The reading section of TEAS contains a total of
40 testing items to answer 58 multiple-choice questions.
This section is a typical reading test where students are asked to read a passage and answer
questions that follow it. It requires students to understand a given text in different ways. Some
questions will deal with literal understanding. Other questions will require students to draw
inferences and form conclusions using their logical reasoning abilities. There can be direct
questions as well as indirect questions based on the passage. However, students should bear in
mind that they have to answer the questions only according to the information given in the
passage and not by referring to any information outside the exam.

1. d – To add or subtract fractions, you need a common denominator. 2/8 reduces to 1/4 1/4 + 1/4 = 2/4 2/4 can be reduced to 1/2. 2. c - To multiply an integer and a fraction, you do not need a common denominator. The numerator of the fraction is multiplied by the integer and the denominator is multiplied by one and stays the same. 4/1 x 3/7 = 12/7 = 1 5/7 3. a – To multiply a fraction by another fraction, multiply numerators and denominators: 5/6 x 3/4 = 15/24 = 5/8 4. b – The quotient of 348 divided by 6 is 58. If you multiply 6 by 58, you get 348 as the product. 5. a – By the order of operations, you first carry out multiplication before addition or subtraction. 8 – 12 + 9 = x -4 + 9 = x X = 5 6. a – By the order of operations, you first carry out division before addition or subtraction. 18 – 23 + 33 = x x = 51 – 23 x = 28 7. c – By the order of operations, you first carry out multiplication before addition or subtraction. A number multiplied by 1 will be itself. Therefore: - 33 – 5 = x x = - 38 8. b – To divide a fraction by another fraction, invert the terms of the divisor and then multiply:
2/3 x 5/4 = 10/12 = 5/6

9. c – An easy way to figure this problem out is to convert the decimal by multiplying by 10, such that .4 becomes 4 and 36 become 360. The division of 360 by 4 may be easier for one to understand. 10. a - By the order of operations, you first carry out multiplication before addition or subtraction. 7 x 9 equals 63 and adding .08 equals 63.08. 11. c - Percent of students that are male = 100% − 45% = 55%
Now, convert 55% to a fraction.
55% = 55 11

12. c - Subtract 25
from 11
to obtain the fraction of the members which are not published writers:
1 2 5 - 2 3
- = =1 5 5 5
Now, convert 35
to a percent by converting its denominator to 100:
3 3 × 20 60= = = 60%
5 5 × 20 100
13. b - Since 25% of A is 48, we can find the value of A by multiplying 48 by the reciprocal of 25
100.
So, ( )100= 48 = 192

204. a - The graph is a straight line and the correct answer is the straight line equation (y = mx + b). Y is the distance along the Y axis. X is the distance along the X axis. B is where the line passes the Y axis. The m is the slope or gradient, or how steep the line is. 205. d - The graph is curved and has two points of intersection with x-axis. Therefore, the quadratic function (d) represents this graph. 206. c - Path of a projectile has only one maximum point. Hence, (c) is the answer. 207. a - The measure of the right angle is 90º. Denote the unknown angle by x. The difference between 90 and x is 32. Therefore, we obtain the equation 90 − x =32. 208. d - Nine times a number is 9x. Adding 9x to 32 yields (9x + 32). Subtracting this expression from 193 gives 193 −(9x + 32) = 161 − 9x. 209. b - Denote the first number by x. Then the second number is (x + 2). Sum of these numbers is 650. Therefore, x + x + 2 = 650 2x + 2 = 650 2(x + 1) = 650 So, 2(x + 1) = 650 can be used to solve this problem. 210. c - Denote the score of the third exam by x. Then (x + 89 + 83) ÷ 3 = 90 or x + 172 = 270. This is the equation we can use to find x. 211. a - Out of the given solutions of x, only x = 1 fits the equation. So, if (x − 1)(x + 3), then x = 1. 212. a - The given ratios are proportional. So, the first ratio implies the second ratio. 213. a - Both x = − 9 and x = 5 are the solutions to the equations, but they do not fit the equation at the same time. Therefore, r or q is true. 214. a − X cannot be both – 3 and – 23 at the same time in this equation. It can only be one or the other to get 0. Using “and” logically means that they are valid at the same time. The term “and” in logic has different meaning from the ordinary language.

TOP Digitally Monitored for Compliance to License Terms © 2013-2014 Tests.com
201
a. 180(n + 1) b. 180(2n − 1) c. 180(n − 2) d. 180(2n − 2) c - The formation of each expression indicates that to find the sum of the interior angles of a polygon, we must subtract 2 from the number of the sides, then multiply by 180. So, for an n-gon, we subtract 2 from n, then multiply by 180. 194. The following set of numbers fit the sides of right triangles:
a = 3 b = 4 c = 5 a = 6 b = 8 c = 10 a = 9 b= 12 c = 15 a = 12 b = 16 c = 20
Using this pattern, find a general formula for the sides of right triangles. a. a = n(3), b = n(5), and c = n(6) b. a = n(2), b = n(4), and c = n(5) c. a = n(3), b = n(5), and c = n(7) d. a = n(3), b = n(4), and c = n(5) d - We can revise the side lengths to relate them to the first triangle as follows:
a = 1(3) b = 1(4) c = 1(5) a = 2(3) b = 2(4) c = 2(5) a = 3(3) b = 3(4) c = 3(5) a = 4(3) b = 4(4) c = 4(5)
So, a = n(3), b = n(4), and c = n(5), where n is a positive integer. 195.

Contents. Highlight those sections which you believe to be important and that will be subject to testing.
9. Meet with Friends who are Studying for the Test and have a Group Discussion - Your friends and colleagues who are studying for the test will have different strength and weaknesses than you. You can benefit each other by sharing information, discussing issues and asking each other questions about the information subject to testing.
10. Don’t Study the Day or Night Before the Test – You have prepared for months. Even though you may feel a bit anxious the day before the test, it is important that you give your brain a rest. During the test, you must be clear of mind and able to nimbly move from question to question. If your brain is tired and your eyes are having trouble focusing, you will put yourself at a great disadvantage. Do not study late into the night. You know the material more than you realize. Take the day off, go for a walk, a bike ride or see a movie.
10 Test Taking Tips 1. Get Good Rest the Night before the Test – All the study in the world will not save you if you can’t
focus your eyes and your mind is cloudy due to staying up late at night to study before the test. Test taking is an art and you must have a clear, well rested mind to do well. An important tip, and the first in this list for a reason, is to get a good night’s rest the day before the test.
2. Eat a Good Meal before Leaving for the Test – Tests usually last a couple of hours. They take much concentration and mental energy.

3. Get to the Testing Location on Time and Mentally Prepare Yourself – You do not want to get lost
on your way to the testing location or leave too late such that you miss the beginning of the exam or even have to rush to get to your seat. You want to arrive in enough time to sit for 10 or 15 minutes prior to the test to collect your thoughts and clear your mind. Make sure you have the address to the testing location the day before the test, ensure you have the right directions or use a GPS system and find out beforehand how much time it will take to get there so you know when to leave.
4. Read the Question and Understand What it is Asking – A cardinal rule of test taking is “Do not read
into the question and Answer only What is Asked.” Before you read the answers, make sure you understand what the question is asking. Do not let yourself insert qualifications into the questions or assume additional fact patterns.
5. Form an Answer in Your Mind before Reading the Answer Options – If an answer comes to you
before you read the answer options, and the answer that came to you matches an answer option,

246
odds are that the answer option corresponding to the answer that popped into your head is the correct answer. You know more than you realize. This is how preparation benefits you.
6. Read all of the Answers - Even though the first answer option looks right, read all of the answer options all of the time. One of the answers is the correct choice. All the information to answer the question is there. Read all the answer options to understand what options are available. You will find, while one of the first top selections seems right some of the time, a bottom option will occasionally be the right selection because it qualifies the answer in the correct way. If you just take the first answer that seems right without reading the other answer options, you will not get the benefit of all the information in the answer options.
7. Eliminate Obviously Wrong Answers – Some of the answer options will obviously be wrong. You
can increase the odds you will select the right answer and work more efficiently by first eliminating obviously wrong answers.
8. Don’t get Stuck on Difficult Questions – Some questions will have difficult or complex fact patterns
that require some thought or calculation. If you find yourself getting lost in the facts or numbers, or stuck on the answer options, such that you start feeling anxious that you are wasting time, take the following steps: guess and register an answer, mark the question with some notation that will tell you it was a guess, and come back to it at the end of the test, after you finished all other questions.
9. Pace Yourself - Don’t Work too Fast; Don’t Work too Slow – Time is a very important element of test taking. Aside from the subject matter, it is the factor that most causes pressure and stress. To obtain a good score, it is important that you have the time to read and answer all of the questions. Tests only allow a certain amount of time per questions. Determine what that time per question is by dividing the time by the number of questions. Pace yourself when taking the test so that you allow yourself enough time to read and answer all questions. You don’t want to work too fast or too slow.
10. Maintain a Good Attitude during the Test – It is important to keep your composure during the test. Having a good attitude will allow you to get through the challenging parts of an exam and avoid becoming down or defeatist, which could slow you down or stop you altogether from finishing the exam. Hang in there and have confidence. If you prepare for the exam following the preparation and test taking tips discussed here, you can have confidence that you will succeed.
