GACE Chemistry

The Chemistry assessment, offered as part of the Georgia Assessments for the Certification of Educators, is divided into two tests.

The first test consists of 60 selected-response questions. The content areas covered by the first test are scientific inquiry, processes, technology, and society; the nature of matter and energy; and nomenclature, chemical composition, bonding, and structure. Some of the topics covered by the scientific inquiry, processes, technology, and society subarea are: scientific inquiry, experimental design, the nature of scientific knowledge, and basic error analysis. Some of the topics covered by the the nature of matter and energy subarea are: the organization of matter, different forms of energy and conservation of energy, the current model of atomic structure, and radioactivity. Some of the topics covered by the nomenclature, chemical composition, bonding, and structure subarea are: the systematic names and chemical formulas of simple inorganic compounds, the mole concept and how it applies to chemical composition, structural formulas and molecular geometry, and how bonding and molecular geometry correlate with physical properties.


The second test consists of 60 selected-response questions. The content areas covered by the second test are periodicity, chemical reactions, solutions, and solubility. Some of the topics covered by the periodicity and chemical reactions subarea are: the basis of the periodic table and general layout, the periodic trends in physical and chemical properties of the elements, how to balance chemical equations, how to perform stoichiometric calculations, and important biochemical compounds. Some of the topics covered by the solutions and solubility subarea are: solution terminology and calculations, factors affecting solubility and dissolution rate, how to define and identify acids and bases, and the equilibrium relationships in acid-base chemistry.

The examination must be completed within four hours. Test-takers will receive performance indices indicating their success in each subarea of the examination. Scores will be available approximately a month after the date of the examination; unofficial results are posted on the internet, and an official score report is mailed to the test-taker, the Professional Standards Commission, and the institution specified by the test-taker during registration.
