There is no fixed number of correct answers required to pass the GED, because the exam uses scaled scoring, not raw question counts. The GED consists of four subjects, each with a different number of questions and time limits. To pass the GED, you must earn a minimum scaled score of 145 out of 200 on each subject—not a set number of correct responses.
Here’s the breakdown by subject:
- Reasoning Through Language Arts: ~46 questions + 1 essay (150 minutes)
- Mathematical Reasoning: ~45–49 questions (115 minutes)
- Science: ~34–40 questions (90 minutes)
- Social Studies: ~34–40 questions (70 minutes)
Because the GED uses computer-adaptive and item-weighted scoring, not all questions are worth the same points. Some complex tasks (like the Language Arts extended response) carry more weight than multiple-choice items. Therefore, you cannot calculate passing by counting right answers.
ETS and GED Testing Service convert your raw performance into a scaled score (100–200) using a confidential algorithm. Generally, scoring about 60–65% correct across items is needed to reach the 145 passing threshold—but this is only an estimate.
What Matters Is the Scaled Score
To pass the GED, focus on achieving 145+ per subject, not a question count. You can miss 30–40% of questions and still pass, depending on which items you get right. The system prioritizes skill mastery over perfection.
Use the official GED Ready practice test ($6 per subject). It gives a scaled score prediction. If you score 150 or higher on practice, you’re likely ready to pass the official exam.
Remember: you must pass all four subjects to earn your credential. You can take them one at a time, on separate days.
Don’t aim for a specific number of correct answers—aim for consistent understanding across core topics.
Your goal is a scaled score of 145+, not a headcount of right responses.
