The Georgia Milestones Assessment System (GMAS) is a statewide math assessment that most Georgia families know by name. What tends to be less clear is what it actually measures at each grade level, how to read the score report, and what readiness looks like before test day arrives.
As a Georgia-based math learning center, Mathnasium of Dunwoody works closely with the standards that Georgia students are assessed on and helps families build the skills those assessments require.
Today, our education specialists walk through what Georgia Milestones math covers at each grade level, how to interpret your child's results, and what to watch for at each stage of their math journey.
The Georgia Milestones Assessment System (GMAS) in math measures how well each student’s understanding aligns with the Georgia Standards of Excellence (GSE). The GMAS math includes two main assessment formats:
End-of-grade (EOG) assessments measure student learning in grades 3–8, including math understanding at each grade level.
End-of-Course (EOC) assessments are given at the end of specific high school courses, such as Algebra I and Geometry, and measure mastery of that course’s content.
At important transition points, especially grades 5 and 8, EOG results can help schools and families understand whether a student is ready for the next step in math.
The stakes are different for EOC assessments. They serve as the course final exam and count toward the student’s final numeric grade. Beginning with the 2023–2024 school year, Georgia’s State Board rule says the Georgia Milestones EOC score must count for at least 10% of the final course grade.
What may surprise you about both formats is how the questions are structured.
Georgia Milestones math is designed across four Depth of Knowledge levels (DOK):
Level 1 covers recall: basic facts and simple procedures.
Level 2 covers skill and concept: applying a known method to a problem.
Level 3 requires strategic thinking: using mathematical reasoning in an unfamiliar context, selecting an approach, and explaining why it works.
Level 4 requires extended thinking: sustained reasoning across multiple steps and representations.
From our work with students, we often see that practiced procedures can carry children through familiar Level 1 and Level 2 questions. Level 3 and Level 4 questions ask for more flexible thinking.
They require students to reason with the math, explain their approach, and apply concepts in less familiar formats. That is why two children may have similar classroom grades but perform differently on Georgia Milestones if one has a solid conceptual foundation.

The GMAS math results are organized into four performance bands. These bands explain how well a student’s performance matches Georgia’s expectations for the grade level or course, giving families a clearer picture than a simple pass/fail result:
Beginning: This is a signal for your child to work on their math foundation before the next transition. Focused support can help them rebuild missing skills, feel more prepared, and move into the next course with greater confidence.
Developing: Some grade-level concepts are still shaky. In non-transition years, targeted help can strengthen those areas before they affect later topics. In grade 5 or 8, it is especially important to act early because the next math placement or course transition may build directly on those skills.
Proficient: A student understands grade-level math well enough to move forward. They are ready for the next stage but still may keep strengthening their skills.
Distinguished: Performance is above grade-level expectations. Your child may be ready for math enrichment or acceleration, especially in transition grades.
To understand which math topics a student should know before GMAS math, use the grade-by-grade overview below. For convenience, we organized the Georgia Milestones math domains and skills by grade level, so you can jump straight to the section that matches your child’s grade.
Third grade is the first year students take the Georgia Milestones math EOG, and it covers two new areas of mathematical thinking: multiplication and division, and fractions as numbers.
In earlier grades, most math work centers on addition and subtraction. In third grade, your child is expected to understand how multiplication and division work and how they connect.
Key skills include:
understand multiplication and division as related operations,
grasp what it means to work with equal groups,
divide a quantity into equal parts,
interpreting multiplication and division in word problems
choosing an equation that matches a real-world situation
explaining what a quotient means
Georgia Milestones can assess these skills through reasoning-based questions along with computation. A student may need to read a situation, decide which operation makes sense, and explain what the answer represents.
Fractions also become more important in third grade. Your child begins to understand fractions as numbers with size, position on a number line, and meaning, instead of as shaded parts of a shape.
They need to understand that \(\Large\frac{1}{2}\) represents a specific quantity and compare fractions using reasoning rather than by looking at pictures.
From our experience, this is a key foundation to watch. If a student leaves third grade thinking of fractions only as “pieces of a shape,” fourth-grade fraction work can become much harder.

Fourth grade builds directly on the fraction concepts introduced in third grade. Students are expected to work with fractions more flexibly and begin connecting fractions to decimals.
Key skills include:
adding and subtracting fractions with like denominators,
multiplying fractions by whole numbers,
understanding decimal notation,
connecting decimals to fractions,
multiplying and dividing multi-digit numbers,
solving multi-step word problems,
explaining why a strategy or operation makes sense.
Georgia Milestones questions in fourth grade may require reading a situation, choosing the right operation, solving in more than one step, and explaining their reasoning.
Your child may know the basic math but hit a wall when the question asks them to decide what to do, justify an answer, or apply the skill in a less familiar format. Fourth grade is a good time to watch whether they can use math flexibly.

Fifth grade is the final elementary Georgia Milestones math assessment and an important checkpoint for middle school math readiness.
For families in Dunwoody and across DeKalb County, the grade 5 score may be one of the data points middle schools consider when placing students in 6th-grade math.
What Georgia Milestones looks for in grade 5:
adding and subtracting fractions with unlike denominators,
multiplying fractions by fractions,
dividing fractions by whole numbers,
working with decimal arithmetic,
understanding volume,
using the coordinate plane,
solving multi-step problems that require reasoning.
At this level, fractions become much more demanding. Your child may complete fraction homework correctly by following the steps, but still get stuck when Georgia Milestones asks for deeper reasoning.
Grade 5 questions may ask students to explain a strategy, apply fraction concepts in a word problem, or recognize why an answer makes sense. According to research by Siegler and colleagues, later success in algebra is strongly linked to how well a student mastered fractions in elementary school.
Pay attention to a Developing score in grade 5, because the concepts the Milestones identified as incomplete are the same ones 6th-grade math will build on immediately.
✍️ Take Mathnasium’s 5th grade Check-Up
The 5th-grade level Georgia Milestones math assessment is an important checkpoint for middle school math readiness.
Middle school math asks students to use earlier skills in more abstract and connected ways. The grade-by-grade overview below shows what Georgia Milestones expects in middle school math and which skills you should watch most closely as your child moves toward high school-level courses.
Sixth grade is a major shift in math. It can expose gaps that were not obvious in 5th grade, especially if fractions, multiplication, division, or proportional reasoning were learned as procedures rather than understood conceptually.
Key skills include:
working with ratios and proportional relationships,
understanding rates and unit rates,
writing and interpreting expressions,
solving equations,
working with negative numbers,
explaining relationships between quantities,
applying math in real-world contexts.
Georgia Milestones questions in 6th grade often ask students to reason through mathematical relationships. A question may ask them to decide whether two ratios are equivalent, explain how they know, or interpret what a negative number means in a real-world situation.
Your child needs to understand what the negative numbers mean, how quantities relate, and why a method works. That deeper understanding may help them handle unfamiliar questions, including the DOK Level 3 questions of this grade’s assessment.

Seventh grade deepens the abstract thinking that begins in sixth grade. Students work more with proportional relationships, rational numbers, expressions, equations, probability, and statistics.
Key skills include:
solving ratio, rate, and proportion problems,
working fluently with positive and negative rational numbers,
solving multi-step equations and inequalities,
connecting expressions and equations to real-world situations,
interpreting probability, data, and statistics,
explaining reasoning in multi-step problems.
By the Georgia Milestones, at this level, students are expected to choose a strategy, use several steps, and explain their thinking. The assessment increases the proportion of multi-step problems and explanation-based questions.
In our work with families, we see the seventh grade become a year when a shaky understanding of fractions, decimals, ratios, or negative numbers can start to affect performance more noticeably.
✍️ Take Mathnasium’s 7th grade Check-Up
Grade 8 is an important transition point because it helps show whether a student is ready for high school math.
For example, for students at Peachtree Charter Middle School moving toward Dunwoody High School, the grade 8 Milestones score may be one of the important data points in high school math placement.
Key skills include:
understanding functions and linear relationships,
interpreting graphs,
solving and reasoning with systems of equations,
working with geometric transformations,
applying the Pythagorean theorem,
interpreting introductory statistics.
8th-graders need to understand how relationships work, what graphs show, and how equations connect to real situations.
At this stage, a Proficient or Distinguished score can show true readiness for Algebra I or a more advanced pathway.
A Developing score deserves careful addressing because the flagged areas, including functions, linear relationships, and algebraic reasoning, are the same skills students will need for the high school EOC assessments.

In high school, Georgia Milestones’ End-of-Course assessments are tied to specific math courses. The main EOC assessments students encounter are Algebra I and Geometry, with additional courses depending on their pathway.
EOC results count toward the final course grade and affect both the course grade and the transcript. Strong EOC preparation starts before high school.
Grade 7 and grade 8 skills, such as proportional thinking, algebraic expressions, linear relationships, and functions, are the foundation for Algebra I and Geometry.
A student who enters Algebra I with these concepts secure can focus on the course itself instead of trying to catch up on middle school gaps.
Effective preparation for high school Georgia Milestones End-of-Course assessments starts with a solid foundation in middle school math.
As we mentioned above, Georgia Milestones rewards flexible thinking through DOK Level 3 questions, which ask students to reason, explain, and apply concepts rather than simply repeat a practiced method.
So before the test, take a closer look at whether your child understands the content well enough to use it in an unfamiliar problem. Watch for these three signs that math understanding may be more procedural than conceptual:
Your child gets correct answers but cannot explain the reasoning behind them. In this case, their understanding may be solid at DOK Level 1 and 2 but thin at Level 3.
They perform well on familiar problem formats but stall when the same concept appears differently. The test regularly presents known concepts in unfamiliar contexts. A student whose understanding is tied to a specific problem type rather than the underlying idea may get lost.
A student completes homework accurately but gets stuck with multi-step or open-ended test questions. They may do well on homework because it follows a clear procedure. Milestones questions at higher levels require more independent reasoning. Repeated difficulty with those questions may mean that the concept is not truly grasped despite a lot of practice.
These signals usually call for deeper concept work. Through a diagnostic assessment, Mathnasium tutors identify your child’s specific knowledge gaps and help to build the math foundation they need for grade-level work and assessments.
Mathnasium tutors support students at different grade levels as they build the skills and confidence needed for Georgia Milestones math.
Georgia Milestones questions can reveal whether a student understands the math deeply enough to explain and apply it, rather than only follow familiar steps. At Mathnasium, our diagnostic assessment is designed to identify that same difference and show where support is needed.
The diagnostic assessment identifies which concepts your child truly understands and which need to be strengthened. For a student preparing for the Milestones, the diagnostic assessment tells you specifically where the DOK Level 3 and 4 questions are most likely to feel hard due to a shaky foundation.
From there, we create a personalized learning plan through the Mathnasium Method™, our proprietary teaching approach, that builds the conceptual understanding that the GMAS math rewards, in the right sequence and at each student’s pace.
Our specially trained tutors use a combination of verbal, visual, mental, tactile, and written techniques to help students truly grasp each concept.
Sessions are designed to develop problem-solving skills and critical thinking in a fun and caring group environment, so students build both the understanding and the confidence to apply it.
