GACE Chemistry (6-12) (712) is Georgia's chemistry content certification test, delivered by Pearson as a computer-based assessment built from four testlets totaling 100 selected-response questions. The testlets and their question counts are Atomic Structures and Properties (214) with 20 questions, Multi-Atomic Structures and Properties (215) with 30 questions, Chemical Reactions (216) with 30 questions, and Energy Changes (217) with 20 questions. To pass you must earn a cumulative score of at least 220 and also meet each testlet's minimum floor. The full assessment fee is $169 ($42.50 per testlet) and the total testing time for all four testlets in one appointment is 3 hours and 30 minutes. This free 100-question bank mirrors the official testlet weighting so candidates can practice across every content area.

Frequently Asked Questions
What is on the GACE Chemistry (712) test?
The assessment is built from four testlets: Atomic Structures and Properties (214, 20 questions), Multi-Atomic Structures and Properties (215, 30 questions), Chemical Reactions (216, 30 questions), and Energy Changes (217, 20 questions). All questions are selected-response, covering atomic theory, bonding, reactions, stoichiometry, equilibrium, acid-base chemistry, and thermodynamics.
How many questions are on the GACE Chemistry (712) test and what is the format?
The full assessment has 100 selected-response questions delivered as four testlets on a computer. You may take any combination of the four testlets in a single session, including all four at once.
What is the passing score for GACE Chemistry (712)?
To pass, you need a cumulative scaled score of at least 220 across the testlets you take, and you must also meet the minimum floor score for each individual testlet. Both requirements must be satisfied.
How much does the GACE Chemistry (712) test cost in 2026?
The full Chemistry (712) assessment fee is $169 when all four testlets are taken together, or $42.50 per individual testlet. Always confirm the exact amount in your Pearson GACE registration account before checkout, since the total depends on how many testlets you select.
How long is the GACE Chemistry (712) test?
Taking all four testlets in one appointment provides 3 hours and 30 minutes of testing time, plus 15 minutes for a tutorial and nondisclosure agreement. If you take all four together, you receive a 15-minute break after the first two testlets.
Is a calculator allowed on the GACE Chemistry (712) test?
GACE provides an on-screen scientific calculator along with a periodic table and a Chemistry constants and formulas sheet within the computer-based testing platform. You do not bring your own calculator, so practice using the provided reference materials.
