About the Course
The ILTS (Illinois Licensure Testing System) issues content area exams as part of the state's teacher credentialing process. If you're an aspiring chemistry teacher, you'll need to take the chemistry test. This paper-based exam includes 125 multiple-choice questions and is administered six times each year. To get an idea of what you'll be tested on, check out this study guide covering the following topics:
- Science and technology
- Life science
- Physical science
- Earth systems and the universe
- Matter, structure and practical knowledge
- Stoichiometry and chemical reactions
Exam questions are divided into six subareas. The first four are found on content area exams for all aspiring science teachers and are designed to assess your general science knowledge across multiple fields. You'll want to brush up on topics ranging from the scientific method and cell biology to Mendel's law and evolutionary theory. Electromagnetism, ecology and astronomy are also among the topics covered by the general science subareas.
You'll get to show off your chemistry expertise in the remaining two sections. These exam questions evaluate your ability to balance nuclear equations, distinguish between types of molecular bonds and calculate a solution's pH levels, among other skills.
Preparing and Registering for the ILTS Science - Chemistry Exam
Our study guide for the ILTS chemistry exam includes plenty of resources to help you get ready for the test, from videos that are easy to navigate to transcripts containing links to vocabulary terms. Each lesson also features self-assessment quizzes that can get you used to how exam questions are formatted.
You can sign up for the exam on the ILTS website. The regular registration deadline typically falls around six weeks before exam day, though late and emergency registration dates are also available for an extra fee. You'll be asked to answer a background question and enter your date of birth, social security number and contact info. You'll also need to decide on a test date and select one of 14 Chicago-area testing sites. To complete registration, confirm your information and print out an admission ticket so you can get into the testing center on exam day.
Scoring the ILTS Science - Chemistry Exam
The exam is scored on a point scale of 100-300. You'll be awarded points for correct answers, and no points will be deducted for wrong or unanswered questions. A score of 240 is needed to pass the exam and meet licensing requirements. You can find out how you did around one month after taking the test, and your score will be valid for five years.
Science and Technology
Questions covering this subarea ask you to demonstrate your ability to form a hypotheses, design an experiment and use the appropriate scientific instruments and tools to carry it out. You should also be able to accurately report any data you collect and explain or defend the results of your research. Your capacity for recognizing how these findings relate to current scientific theories and laws is also tested. Other questions on this part of the exam require you to identify biases in scientific research. You should also be able to recognize the processes by which a scientific breakthrough becomes technology that can solve real-world problems.
The life science subarea is where you'll demonstrate your familiarity with the structures and organelles characteristic of eukaryotic and prokaryotic cells. The processes involved in cellular reproduction, gene transmission and expression are covered on this part of the exam as well. You should also be able to recognize some of the behavioral and physiological traits that help organisms maintain homeostasis. A knowledge of how a food web or ecological pyramid can be used to illustrate the relationships between individual organisms is also required, as is a recognition of how various species populations make up communities, which in turn comprise ecosystems and ecoregions. You'll also want to be aware of the scientific evidence explaining evolutionary theories.
Physical science questions ask you to identify the processes by which thermal, electrical, chemical and other energy types are transformed or exchanged. Explaining or solving mathematical problems associated with these processes will require you to be familiar with the laws of thermodynamics. You'll also need to be aware of how protons and electrons determine an element's atomic structure. Additional questions ask you to use algebra to calculate force, velocity and acceleration of an object in projectile motion. You should also be able to explain how moving and static charges can be used to generate electrical power and describe the properties of waves.
Earth Systems and the Universe
Questions included in this subarea test your understanding of the scope and sequence of geologic time as well as theories explaining the origin of the universe. You'll need to be familiar with the Earth's structural composition, its atmospheric layers and its water system. An awareness of how these components are affected by rock cycles, plate tectonics, earthquakes and volcanoes is also necessary for this part of the exam. Additionally, you should be able to explain planetary orbits and the properties and life cycles of comets, asteroids, black holes and supernovas.
Matter, Structure and Practical Knowledge
This subarea is where you'll use algebra, statistics and calculus to solve mathematical problems associated with chemistry. These questions also assess your ability to safely set up and conduct chemistry experiments. Others ask you to identify elements' electron configurations based on their positioning on the periodic table and show how their valence loads determine the types of chemical bonds that are formed.
Additionally, you should be able to tell the differences between physical and chemical changes, describe the progression of atomic theory and use kinetic molecular theory to explain changes in states of matter. You'll also need to identify the proper calculations for preparing solutions of varying molarity or molality.
Stoichiometry and Chemical Reactions
To do well on this part of the exam, you'll need to be able to balance chemical equations and solve problems involving percent yield in stoichiometeric equations. Questions also cover the role molecular structure plays in determining a solution's pH and the differences between acids and bases. You should be able to prepare a buffered solution and calculate energy changes taking place during a chemical reaction as well. Other questions touch on electrolysis and redox reactions and the components of an electrochemical cell before moving on to evaluate your familiarity with ways temperature and the presence of catalysts alter chemical reaction rates.
You might also want to brush up on your knowledge of organic chemistry. This section asks you to identify the structure and properties of biological molecules like carbohydrates, proteins and lipids. You should also be aware of common reactions that take place among organic molecules, like substitution and elimination.
