You need a cumulative score of 220 or higher, and you must also meet the floor score for each individual testlet. Scoring well on three testlets doesn’t offset falling below the floor on the fourth — both conditions have to be met. Reference materials are provided on-screen for every testlet: a scientific calculator, a periodic table, and a Chemistry (6–12) Constants and Formulas sheet.

⏳

Budget extra time beyond the testing minutes themselves. Add 15 minutes per testing session for a tutorial and to complete a nondisclosure agreement. If you take all four testlets in one appointment, you’ll also get a 15-minute break after finishing the first two testlets.

About the GACE Chemistry (6–12) (712)

Here’s what you need to know before you register.

The GACE Chemistry (6–12) exam is for individuals seeking admission to an educator preparation program, initial certification in Georgia, or qualification to teach chemistry in Georgia secondary schools. It is administered through Evaluation Systems of Pearson on behalf of the Georgia Professional Standards Commission (GaPSC).

The exam is made up of four testlets, which you can take together in one session or separately. Testlets 215 (Multi-Atomic Structures and Properties) and 216 (Chemical Reactions) are the largest, each with 30 questions and a 60-minute time limit. Testlets 214 (Atomic Structures and Properties) and 217 (Energy Changes) are shorter, each with 20 questions and a 45-minute time limit. Combined, all four testlets total 100 questions in 3 hours and 30 minutes. All four testlets cost the same — $42.50 individually or $169.00 combined.

Plan for extra time beyond the testing minutes themselves: add 15 minutes per testing session for a tutorial and to complete a nondisclosure agreement. If you take all four testlets in one appointment, you’ll get a 15-minute break after finishing the first two testlets.

The exam is delivered entirely by computer in a selected-response (multiple-choice) format. You’ll have on-screen reference materials available for every testlet: a scientific calculator, a periodic table, and a Chemistry (6–12) Constants and Formulas sheet. You don’t need to memorize constants or formulas — you need to know how and when to apply them.

To pass, you need a cumulative score of 220 or higher, and you must also meet the floor — the minimum required score — for each individual testlet. Scoring well above 220 on three testlets doesn’t make up for falling below the floor on the fourth. To register, create a GaPSC MyPSC account at mypsc.gapsc.org, then create an Evaluation Systems GACE testing account at gace.es.pearson.com.

Testlet 214

Atomic Structures and Properties — Top Topics

20q · 45 min
Atomic structure and subatomic particles. Know the properties of protons, neutrons, and electrons, and how atomic number and mass number determine an element’s identity and isotopes.
Periodic trends. Know how atomic radius, ionization energy, and electronegativity change across periods and down groups, and how these trends predict chemical behavior.
Compound formation and nomenclature. Know how to name ionic and covalent compounds correctly, including prefixes, oxidation states, and polyatomic ions.
Mixtures and separation techniques. Know the difference between homogeneous and heterogeneous mixtures, and the separation techniques used for each — filtration, distillation, and chromatography.
Testlet 215

30q · 60 min
Molecular geometry and VSEPR theory. Know how to predict molecular shapes from electron domain arrangements, and how shape determines polarity and physical properties.
Bonding theories. Know the differences between valence bond theory and molecular orbital theory, and how each explains bond formation and molecular stability.
Intermolecular forces. Know the four types — London dispersion, dipole-dipole, hydrogen bonding, and ion-dipole — and how each affects boiling point, melting point, and solubility.
Structure-reactivity relationships. Know how molecular structure influences chemical reactivity, including the role of functional groups and bond strength.
Testlet 216

Reaction types and balancing equations. Know how to identify synthesis, decomposition, single replacement, double replacement, and combustion reactions, and how to balance equations using conservation of mass.
Stoichiometry calculations. Know how to convert between moles, mass, and particles, and how to identify limiting reactants and calculate percent yield. The on-screen calculator handles the arithmetic — you need to know which calculation to set up.
Reaction rates and equilibrium. Know the factors that affect reaction rate — temperature, concentration, surface area, and catalysts — and how Le Chatelier’s principle predicts equilibrium shifts.
Oxidation-reduction reactions. Know how to identify oxidizing and reducing agents, assign oxidation states, and balance redox equations.
Testlet 217

Energy Changes — Top Topics

20q · 45 min
The laws of thermodynamics. Know the first law (energy conservation) and second law (entropy) of thermodynamics, and how they apply to chemical systems.
Enthalpy and calorimetry. Know how to calculate heat absorbed or released using calorimetry, and how to distinguish endothermic from exothermic reactions.
Entropy and Gibbs free energy. Know how entropy and enthalpy combine to determine Gibbs free energy, and how the sign of ΔG predicts whether a reaction is spontaneous. The Constants and Formulas reference sheet gives you the equation — know when to use it.

Who Needs the GACE Chemistry (6–12) (712)?

Find out if this is the right exam for your teaching goals.

Georgia Requirement: You need the GACE Chemistry (6–12) (712) if you are seeking a Georgia teaching certificate in Chemistry for grades 6 through 12. You must pass all four testlets (214, 215, 216, and 217) to earn the full certification — meaning a cumulative score of 220 or higher, plus meeting the floor score on each individual testlet.

How to register: Start by creating a GaPSC MyPSC account at mypsc.gapsc.org to get your Georgia certification number. After your eligibility is confirmed, create an Evaluation Systems GACE testing account at gace.es.pearson.com/test/712 and register for your testlets. You can take all four testlets together in one appointment or separately in any combination. Always verify current certification requirements at gapsc.com.

How to Prepare for the GACE Chemistry (6–12) (712)

Here are some tips to help you get ready for each testlet.

  • Testlets 215 and 216 are your largest testlets at 30 questions and 60 minutes each — prioritize your study time accordingly. Together they make up 60 of the 100 total questions on the exam, so a strong showing on molecular structure, bonding, and chemical reactions carries more weight toward your cumulative score than any other pair of testlets.
  • Because you must meet the floor on every testlet, don’t neglect Testlets 214 and 217 just because they’re shorter. At 20 questions and 45 minutes each, these testlets carry fewer points, but falling below the floor on either one means you don’t pass — regardless of how well you scored elsewhere.
  • Get comfortable with the on-screen scientific calculator, periodic table, and Constants and Formulas sheet before test day. You won’t need to memorize constants like the gas constant or Avogadro’s number, but you do need to know which formula applies to which type of question so you’re not searching the reference sheet under time pressure.
  • For Testlet 216 (Chemical Reactions), stoichiometry calculations are your highest-value practice area. Work through mole conversions, limiting reactant problems, and percent yield calculations until they feel automatic, since this is the largest testlet on the exam.
  • Plan your appointment around the built-in break. If you take all four testlets together, you’ll get a 15-minute break after finishing the first two. Use it deliberately — step away from the screen, and mentally reset before Testlet 216 and 217.
  • Use the Georgia Standards of Excellence for Science as your primary content reference. The Georgia GSE for Science tells you what depth of chemistry content is expected at the secondary level, and it’s the standard the GACE Chemistry exam is built around.
