1- Important Tidbits: There are a few important details you need to know, like the cost of the test, where to take it, and how many times you CAN take it. 2- What to Know: Each subtest focuses on a specific set of skills and knowledge. We breakdown the specific concepts, ideas, and skills you need to pass EACH subtest.

3- Testing Tips: How you answer each question is important. Did you know there are mathematically-proven ways to increase your chance of passing? 4- Practice Test: Get an idea for the kinds of questions on each subtest and see how well you know the concepts. 5- Helpful Resources: Let us tell you the best resources to use to get the in-depth preparation you need to pass the CORE Subjects EC-6! The TExES CORE Subjects EC-6 is the test you must pass to teach at the elementary level in Texas. The exam consists of 5 individually graded subtests with a total of 267 multiple choice questions. You will have 5 hours to complete all five subtests.

The CORE Subjects EC-6 is difficult because you must pass each subtest (older versions of the test required a simple passing score) and each subtest is individually timed. This page will give you a breakdown of the exam, what you need to know for each subtest, provide testing tips and strategies, a practice test, and resources.

Keep scrolling down for this great information. Table of Contents. Cost: $131 for the CORE Subjects EC-6; $65 per subtest (if registering for an individual subtest(s)). Locations: The CORE Subjects EC-6 is a Computer-Administered Test (CAT), so it can be taken at numerous locations across Texas, as well as a few locations outside of Texas. Limited Number of Attempts: The state of Texas allows a person only 5 attempts to pass the CORE Subjects EC-6 before requiring a waiver for a 6 th attempt. The process to get a waiver is time-consuming and expensive so it is best to prepare and pass the first time.

For more information, contact the or your Educator Preparation Program. Who can take the test: Almost anybody. If you are not a certified teacher and not in an Educator Preparation Program, you can take the exam.

All you have to do is register as a Pre-Admission Content test-taker. If you are a certified teacher, you can just register for the exam. If you are in an Educator Preparation Program, you can simply request test approval from your certification program.

The English Language Arts and Reading portion of the exam is going to focus on the best practices to help students learn to read and write. Concepts, such as phonemic awareness, phonological awareness, oral language development, and reading comprehension, will be covered on the exam. Not only will a test-taker have to be familiar with the concepts, but also know the best practices for implementing instruction in the classroom. The English questions on the CORE Subjects EC-6 will be mainly pedagogical- the questions will ask how best to teach the concepts to students. That means a test-taker must be familiar with the concepts and also the best way to implement the concepts in a classroom setting. The foundation of good preparation will be an understanding of English Language Arts terminology and the best practices of English Language Arts instruction.

One concept the test-taker should be familiar with is “scaffolding”. Scaffolding refers to supporting student learning by building new concepts upon familiar concepts- similar to how scaffolding helps support structure that is being built. Students learn better when the new information they process is conceptualized and taught through concepts they already know. On the Reading and Language Arts, knowing how to best scaffold instruction when teaching the concepts (such as phonemic awareness, phonological awareness, oral language development, and reading comprehension) is essential to passing the exam. A helpful source to learn the best practices in Reading and Language Arts is the pamphlet.

The mathematics subtest can be the most intimidating for many test-takers. The reason is many test-takers do not feel comfortable with math, yet alone answering twenty-four math questions that range from solving for “x” to calculating a probability of a die roll to how best to teach fractions to fifth-graders. The good news is that the mathematics tested on the CORE Subjects EC-6 is, for the most part, basic mathematical skills that are used fairly often.

When test-takers start to review for the mathematics questions they often find they remember much more than they thought and that math is easier now than when they were in school. The numbers, operations, and algebraic thinking questions will be about patterns, whole numbers, rational numbers, basic operations (addition, subtraction, multiplication, and division), variables, and how best to apply formulas. Understanding how to use formulas (ETS will provide a reference sheet of formulas) and when to use formulas is essential for success on the mathematics subtest. The geometry, measurement, and probability questions (transformations-rotations, reflections, etc., length, time, and mass) will require the test-taker to interpret data presented graphically, and basic questions regarding statistics (mean, median, mode, and range). To be successful on these questions the test-taker should have a broad understanding of how the mathematical concepts are used in a variety of contexts.

A broad review consisting of content and practice questions is highly recommended; proper preparation for the mathematics exam requires working many practice questions to ensure one understands how best to implement the concepts. Math builds upon itself more so than any other area. Addition must be learned before multiplication; multiplication must be learned before fractions. Because of this, the test-taker should have a comprehensive mathematics review.

Many times, if a test-taker is confused in one area of mathematics, then that confusion will lead to trouble in many different areas. Being up-to-date on a wide spectrum of knowledge is critical to passing the mathematics subtest successfully. All math questions on the CORE Subjects EC-6 are multiple-choice. A multiple-choice math exam is the easiest way to take a math exam. A great strategy to use on a multiple choice mathematics exam is “Guess and Check”. Don’t be afraid to plug all answer options into a problem to see which answer works best. Use all the advantages you can on the math subtest.

The United States history and government questions will focus primarily on how the United States began and how those beginnings influenced the nation and its leaders up until the present day. Key events such as the Mayflower Compact, the Revolutionary War, and the Gettysburg Address will be tested upon, as well as the ideology reflected in the events. The better understanding one has of the cause and effect relationship upon political ideology and important historical events of the United States; the better one will be able to answer history and government questions. The geography questions will focus on the interaction between humans and their environment. Understanding how humans change the environment and how the environment catalyzes human adaptation are essential to correctly answering questions in this category. Also, it is very helpful to have a broad knowledge and understanding of influential cultures (Egyptian, Greek, Roman, etc.) and their impact on western civilization.

The world history questions will focus on the contributions of classical civilizations to modern western civilization. The broad political, social, and military influences of Greece and Rome will appear on the test; the test-taker needs to understand how important ideas and events from these civilizations influenced leaders of western countries. Economic questions will largely center around basic economic concepts such as supply and demand, scarcity and choice, and the influence of government in the market. Social Science is primarily a study of cause and effect. History can be seen as one event leading and shaping another event (one reason studying timelines is so important). The study of geography is important because it examines how humans interact with their environment; geography seeks to understand how environmental causes affect human behavior. The same is true of economics and government.

How does human interaction cause events and behavior and how does human interaction affect events and behavior? Studying the Social Sciences through this perspective can be helpful because it provides a context for the concepts. More pragmatically, the more a test-taker understands historical events, the easier it is to eliminate answer options on the CORE Subjects EC-6. The earth science questions will be about the structure, properties, and processes of the earth.

Geological structures and formations, properties of solid Earth, and the water cycle are all aspects of earth science that will be tested. Earth science encompasses concepts such as: the formation of the earth, how to understand the age and structure of the earth, various cycles essential to life on the earth, and the impact of humans on the earth. Understanding how all these different concepts affect one another is important to having a full understanding of earth science.

The life science questions will be about adaptations in living organisms, the role of genetics, the effect of ecosystems on life, the effect of substances on life (i.e. Nutrition, disease, drugs). Life science is best encompassed by the field of biology and the study of life on earth.

Having a broad understanding of basic life processes, such as the function and structure of a plant and animal cell, is essential to successfully answering life science questions. The physical science questions will be about the physical and chemical aspects of life and forces found in the universe. Understanding the laws of motion, the types of forces (applied force, electrical force, magnetic force, etc.), and how they are revealed in nature is essential in correctly answering the physical science questions. The information tested by the Science subtest is on the level of concepts taught in an elementary classroom- so the information is not very technical or detailed. However, there is a lot of information taught in an elementary classroom so the test-taker should be up-to-date on their scientific knowledge. Passing the test can be a difficult thing, but luckily, we have developed some great strategies that will help you increase your score up to 10 points!

One of our strategies is a 4-step guide on how to answer a question: Step 1: Read the question for a general comprehension. What is the question about? This first step is to get a general idea of the question and a framework for what is happening in the question. Step 2: Re-read the question The second time you read the question look for: -What is the question asking? This is the sentence with the question mark at the end.What is the age of the students?

(If students are mentioned) -What information is important in the question? Not all information in the prompt is relevant for the question. Step 3 & 4: Read each answer option, and then re-read each answer option. As you first read the answer options, try to not make a judgment if it is a correct answer. On the second reading, try to eliminate the incorrect answers BEFORE trying to identify the correct answer.Answers at the bottom 1.

Answer Choice (C). This is the best answer. A research paper requires students to cite their sources for the research. Answer Choice (B). Phonemic awareness is the ability to hear, identify, and manipulate individual sounds in spoken words. Answer Choice (D). Phoneme deletion is not an easy task and can take some students until the ages of 8 or 9 to master. Answer Choice (A). Single, closed-syllable words are the most basic words and decoding instruction should start with the most basic words.

Examples of single, closed-syllable words include mom, dad, pen, top, hat, etc. Answer Choice (C). A phoneme is the smallest unit of speech that can be used to make one word different from another word. In the word “hat” the sounds /h/, /a/, and /t/ are all distinct phonemes. Answer Choice (B). This is the best option because students must first preview the information before analyzing the information. Answer Choice (C). This is correct because the main method of evaluating reading fluency and determining the reading level is to count the number of words the students read correctly during one-minute of reading. Answer Choice (D). The stages of the writing process are: Brainstorming, Outlining, Rough Draft, and Revise/Edit the writing.

Holding peer conferences is an appropriate activity during the revising/editing stage of the writing process because students can provide feedback on each other’s work. Answer Choice (A). The prewriting stage is when the students collect their thoughts, resources, and possibly an outline for a writing assignment.

Allowing students to verbally communicate to organize their thoughts is a great support for early elementary education students. Answer Choice (A). Latin is the root language of many European languages, as well as English. Because of the common ancestry of many English words and words of other European languages (German, French, Spanish, etc.), it is likely that speakers whose native language is historically related to English are able to make intuitive guesses about the spellings and meanings of the words. Answer Choice (A). Children in the second grade, ages 7 and 8, would be at the 'concrete operational' level, according to Piaget. At this level, students are able to understand the concept of reversibility. This is the best concept to introduce because it is in-line with the students’ cognitive development. Answer Choice (A). This is correct because having the student count the number of cubes and placing the cubes next to each item provides a visual for the student to use in determining the length.

Answer Choice (B). 63. 31 = 1953. The digit that occupies the hundreds place is 9. Answer Choice (B). The median is simply the middle term. In this set, however, there are 20 terms so the middle two terms are 4 and 5. The median in this case is the average of the two middle scores: (4+5)÷2 = 4.5: median = 4.5. The mean is the sum of all of the numbers in the data set divided by 20, the number of items in the data set: 101 ÷ 20 = 5.02.

The mean is about 5.0. The mean is written as 5.0 because the value has been rounded to the nearest tenth; writing the mean as 5 would indicate that it is an exact whole number, 5. Answer Choice (D). This is the correct situation for the given equation. 54 months divided by 12 months per year gives us 4 ½ years. Answer Choice (A). Slope-intercept form is y = mx + b where M can be a numerical value and B is a constant.

Or described another way, M is the slope of x and y is the point where the line intercepts with the y-axis. This is why it is called slope-intercept form. Answer Choice (A). Complementary angles are two angles whose sum is 90 degrees. So if one angle is 68 degrees, its complement would be 90 – 68 = 22 degrees.

Answer Choice (B). The progression of geometric thinking is: Visualization - Analysis - Abstraction - Deduction. Visualization is the ability for a student to identify a shape based on its appearance (it's a square because it looks like a square). Analysis is the ability to identify a shape based on properties (it’s a square because it has four equal sides). Abstraction is where students form abstract definitions about shapes (all squares are rectangles, not all rectangles are squares).

Deduction is the ability to prove statements about a geometric shape are true (geometric proofs). Answer Choice (C). To find the answer to this question set up a ratio; remember that 30% =.3 and 100% = 1. (20 /.3) = (X / 1). When you cross multiply to solve for X, you get the equation.3x = 20.

Divide each side by.3 to isolate X and the answer is 66.66666. The best answer choice is 67 minutes. Answer Choice (D). The probability of getting any number on a six-sided die is one out of six (1/6), because there are six equally possible sides. The probability of a coin landing on tails is one in two (1/2) because there are two equally possible outcomes. To find the probability of a 1/6 instance happening at the same time of a ½ instance, simply multiply the probabilities together. This yields (1/6). (1/2) = (1/12).

Answer Choice (C). The name of the United States of America denotes a political region that is under the governing of the United States government. Within the United States of America there are many languages, religions, and climates. Answer Choice (B). A history textbook would be a secondary source of information. Answer Choice (C). The major effect of the Industrial Revolution on life in America was to encourage the movement of families from rural areas to cities, where urban living provided higher wages and opportunities for advancement. Answer Choice (B). This is correct because the family unit uses storytelling to convey knowledge about culture and society.

Answer Choice (D). Jacques Cartier was the first Frenchman to explore North America. He was sent in 1534 under commission from the French king to find a western passage to the lucrative markets of Asia. A secondary goal of Cartier, and subsequent French explorers, was establishing land claims for France. Eventually the land claims proved to be profitable and the hope of finding a western passage was discarded. As more French explorers claimed North American land and established forts for France, French missionaries and adventurers migrated to the New World to convert Indians and capitalize on the emerging lucrative fur trade. Answer Choice (B). The Stamp Act of 1765 enacted a tax on all newspapers along with legal and commercial documents.

It was protested by the Sons of Liberty and repealed by the British government in 1766. Answer Choice (C). Europeans classified the Africans by ethnicity and language. This caused many conflicts between the groups long after the effects of European colonization diminished. Answer Choice (B). An oligopoly is a market where only a few firms supply a good or resource. A few examples would be Anheuser-Busch and MillerCoors which produce 80% of the beer sold in America; AT&T, Verizon, T-Mobile, and Sprint which control roughly 89% of the cellular telephone service in the U.S.

Answer Choice (D). A tariff is a tax on products imported or exported from a country. This is a good example of a tariff.

Answer Choice (B). The Fifteenth Amendment prohibits the denial to vote based on race, color, or previous servitude. Answer Choice (B). The nervous system contains the brain, spinal cord, and nerves. The brain controls all functions of the body.

Answer Choice (A). Dead and decaying plants and animals are the source of nutrients in the soil. Decomposers break down the tissue of dead plants and animals, returning the nutrients to the soil. Answer Choice (D). Human males generally have one X chromosome and one Y chromosome and human females generally have two X chromosomes. A Y-chromosome genetic trait will only pass the male offspring of a human male. Answer Choice (A). When wood burns chemical energy is converted into heat energy because some of the chemical energy stored in the chemical bonds of the substances in wood is released as heat during the combustion process. Answer Choice (C). Potential energy is the stored energy of an object; it is the energy by virtue of an object’s position relative to other objects. In regards to the pendulum, at what point of the pendulum’s swing does the pendulum have the most potential, or stored, energy?

The answer is at the top of the arc because the pendulum is not moving upward or downward, but because of gravity will have to swing downward. Thus, at the top of the arc the pendulum has the greatest potential energy. Answer Choice (B). Chemical energy is energy stored in the bonds of a chemical compound. The breaking of the chemical bonds releases energy, usually in the form of heat.

Answer Choice (B). Igneous rock is rock that is solidified lava or magma. Answer Choice (C). The lunar cycle is a result of the moon orbiting the earth in relation to the sun. The illumination of the moon by the sun from the perspective of the earth allows people on earth to track the lunar cycle. As the moon orbits the earth, different angles of the moon are visible from earth because of how the moon is illuminated by the sun.

This variance in illumination from the perspective of earth results in people on earth being able to monitor the orbit of the moon. Answer Choice (C). The Coriolis Effect is the apparent deflection of moving objects when the motion is described relative to a rotating reference frame. In the context of the answer option, it is the appearance that global winds spiral downwards from the viewpoint of the Earth. Answer Choice (A). Graduated cylinders have graduated milliliter measurement lines to measure volume. Answer Choice (A). Since Terrance lives near a river, water would be the best choice for an energy resource. Hydroelectric energy is possible with flowing water. Answer Choice (B). This is the correct order for the taxonomic rank.
