Questions in the test's style, each with the answer and an explanation. Open the answer once your child has tried the question.
Question 1 · Grade 8 Math · Standard NC.8.EE.7
Solve: 3(2x + 4) = 30
- A.x = 2
- B.x = 3
- C.x = 4
- D.x = 5
Show the answer and explanation
Answer: B. x = 3
6x + 12 = 30. Subtract 12: 6x = 18. x = 3.
Question 2 · Grade 8 Math · Standard NC.8.G.9
A cylinder has a radius of 5 cm and a height of 10 cm. What is the volume? (Use π ≈ 3.14)
- A.157 cm³
- B.314 cm³
- C.628 cm³
- D.785 cm³
Show the answer and explanation
Answer: D. 785 cm³
V = πr²h = 3.14 × 25 × 10 = 785 cm³.
Question 3 · Grade 8 Math · Standard NC.8.SP.1
A scatter plot of hours studied vs. test scores trends upward from left to right. This indicates —
- A.A negative association
- B.No association
- C.A positive association
- D.A nonlinear association
Show the answer and explanation
Answer: C. A positive association
Upward trend = positive association: as hours studied increase, test scores increase.
About the NC EOG Grade 8 Math Test
Grade 8 is the hardest NC EOG math grade: 52.8% of eighth graders who took the Grade 8 EOG were grade-level proficient in 2025-26 — the lowest of grades 3-8, though up from 48.5% in 2024-25. It's also the bridge to high school: Functions is the biggest reporting category (~28-32%), and the content is built around linear relationships, the foundation of Algebra I. Note that some eighth graders take NC Math 1 (an End-of-Course test) instead of the grade-8 EOG; this page covers the grade-8 EOG.
North Carolina reports four achievement levels (Not Proficient, Level 3, Level 4, Level 5); "on grade level" is Grade Level Proficient (GLP), Level 3 or above.
The EOG has a 15-item calculator-inactive section and a 30-item calculator-active section. Grade 8 is the one grade where the online test provides a graphing calculator on the active section (in addition to a scientific one).
Grade Level Proficient (GLP) = Level 3+ = on grade level — the lowest EOG math grade (52.8%). Students who took NC Math 1 in or before grade 8 do not take the Grade 8 math EOG. Level 4+ = College-and-Career Ready.

What's On The NC EOG Grade 8 Math Test
Grade 8 math on the NC EOG is organized into reporting categories from the NC Standard Course of Study, with Functions the largest. The percentage ranges are from NCDPI's published test specifications.
| Reporting Category | What's Tested |
|---|---|
| Functions (~28-32%) | The biggest grade-8 category: understanding functions and graphing and interpreting linear relationships (slope, intercept, rate of change). The direct on-ramp to Algebra I. |
| Geometry (~24-28%) | The Pythagorean theorem, transformations, and volume of cylinders, cones, and spheres. |
| The Number System + Expressions & Equations (~24-28%) | Linear equations and systems, exponents and scientific notation, and rational vs. irrational numbers. |
| Statistics & Probability (~16-20%) | Analyzing bivariate data and lines of best fit. |
Test Format — What Your Child Will See
- ●Grade 8 is the lowest EOG math grade (53% grade-level proficient in 2025-26).
- ●Functions and linear relationships are the core — the on-ramp to Algebra I. Some students take NC Math 1 instead.
- ●Graphing calculator available on the active section at grade 8.
What North Carolina Parents Should Know About Grade 8 Math
- 1
Master functions and linear graphs — the biggest grade-8 category and the heart of Algebra I. Reading slope and intercept off a graph is the key skill.
- 2
Lock in the Pythagorean theorem and exponent rules — concrete, high-frequency, reliable points.
- 3
Treat grade 8 as real prep — it's the lowest EOG math grade (53%), so focused review moves the needle.
- 4
Use the graphing calculator well on the active section, but keep by-hand fluency for the inactive section.
NC EOG Grade 8 Math — Frequently Asked Questions
Can my child use a calculator on the 8th grade NC EOG math test?
On the 30-item calculator-active section, yes — a scientific calculator, with a graphing calculator also available online at grade 8. The 15-item calculator-inactive section has none.
What math is on the 8th grade NC EOG?
Built on the NC Standard Course of Study: Functions (the biggest category — functions and linear graphs, the on-ramp to Algebra I), Geometry (Pythagorean theorem, transformations, volume), Number System + Expressions & Equations (linear equations, exponents), and Statistics & Probability.
Do all 8th graders take the grade-8 NC EOG math test?
No — students enrolled in NC Math 1 take that End-of-Course (EOC) test instead of the grade-8 EOG. This page covers the grade-8 EOG.
How many NC 8th graders are proficient in math?
In 2025-26, 52.8% of North Carolina eighth graders who took the Grade 8 math EOG were grade-level proficient — the lowest EOG math grade, though up from 48.5% in 2024-25.
When is the NC EOG in 2027?
EOGs must be given in the last ten days of the school year (late spring 2027 on a traditional calendar); your district sets exact dates.
