About This Course
This course provides an opportunity for a comprehensive review of the material you may see on the National Evaluation Series (NES) Chemistry exam. This exam has replaced the Washington Educator Skills Test - Endorsements (WEST-E) Chemistry. The course is composed of a series of chapters that cover topics such as matter, atomic structure, inorganic and organic compounds, chemical reactions, and the nature of science. Each chapter is organized into a series of engaging lesson videos that you can watch on your computer or mobile device. Additionally, the course includes lesson quizzes, chapter exams and a final assessment that helps you test your understanding of the material before you take the exam.
Check out our WEST test prep materials! We've got WEST courses to teach you the material, comprehensive WEST study guides to help you study, WEST practice tests to test your knowledge, and informational WEST resources to get you up to speed on testing logistics.

Syllabus & Course Information
The course was designed to coincide with the topics that you'll need to know for the NES Chemistry exam. You'll get an overview of the nature of science, as well as fundamental concepts related to chemical reactions, atomic structures, solutions, stoichiometry and much more. The lessons also highlight key formulas and definitions. When you finish the course, you should be able to:
- Recognize properties and states of matter
- Evaluate atomic structures and quantum theory
- Explain the laws of thermodynamics
- Describe the chemical bonding process
- Balance chemical equations
- Compare acids, bases and solutions
- Assess the properties of solutions
This course is broken into 15 chapters, and you can expect to review a total of 138 lessons. The lessons are typically less than ten minutes in length, and you're encouraged to take the accompanying assessments to help retain the information you study.

Preparing & Registering for the NES Chemistry Exam
Start your review of the material in this course by watching the lesson videos of the first chapter. Quizzes are included that can be used to test your knowledge of what was covered in the course. You can print out worksheets of your test results and use them as a paper resource that you can study when you're away from your computer. Questions can be submitted to our instructors when you utilize the 'ask-an-expert' feature.
You can register for the exam at the Washington Educator Skills Tests' website. Tests are offered year round, Mondays through Saturdays, in locations nationwide as wells as in the state of Washington. If you need to, you can change the date, time or location of a testing session as long as you do it at least 24 hours before the time of your exam. You may also withdrawal from testing as long as you do so no less than 24 hours prior.
