AEPA Chemistry Exam

The Chemistry test measures your knowledge according to the Arizona Academic Standards. Success on the test indicates that you are qualified to teach chemistry in Arizona public schools. The test content is drawn from five subareas based on AEPA learning objectives: Scientific Inquiry (23% of the test); Matter and Atomic Structure (23%); Energy, Chemical Bonds, and Molecular Structure (20%); Chemical Reactions (19%); and Quantitative Relationships (15%). The test covers the principles and procedures of scientific investigation and chemistry (including safety issues), as well as the relations between chemistry and other sciences and society, both historically and today. The Matter and Atomic Structure section includes content on the chemical and physical properties of matter, quantum theory, and key topics regarding atomic structure (including subatomic particles). Test-takers should also know how the periodic table is organized, conventions of chemical notation, kinetic theory, phase changes, gas laws, and nuclear transformation. Test-takers should be familiar with the principles of thermodynamics, calorimetry, and bonding and reactions (e.g., bonds between atoms). The test also covers molecular interaction and the nomenclature and structure of organic compounds. Other content regards acid-base chemistry, various chemical reactions (redox, organic, electrochemical), reaction rates, and the principles of chemical equilibrium. Lastly, the test requires knowledge of quantitative relationships (e.g., related chemical equations, the mole concept, and solutions).
