How Hard is the Praxis Chemistry?

The Chemistry exam represents another challenging assessment in the Praxis series. A major reason for the Praxis Chemistry's difficulty stems from the specified content on the test. Candidates taking this test will need detailed knowledge of certain chemical reactions, scientific methods, and the history of chemistry in general.

Whereas some Praxis tests, such as those focusing on English Language Arts and Spanish, only require candidates to have more general knowledge of certain skill areas, the Chemistry test requires candidates to understand exact facts and equations, which can make the exam much more difficult.

Praxis Chemistry Content

The Praxis Chemistry consists of 125 selected-response questions. Questions on the Praxis Chemistry assessment fall into one of seven content categories:

  • Scientific Inquiry & Social Perspectives of Science
  • Nomenclature; Chemical Composition; Bonding & Structure
  • Scientific Procedures & Techniques
  • Basic Principles of Matter & Energy; Thermodynamics
  • Solutions & Solubility; Acid-Base Chemistry
  • Atomic & Nuclear Structure
  • Chemical Reactions; Periodicity

Distribution is spaced out fairly evenly among the seven categories on the test. All categories make up between 12 and 15 percent of the test, with the exception of the Chemical Reactions; Periodicity section, which constitutes 20 percent of the exam.
