Understanding the IB MYP 1–7 Grading Scale (and Why You See Scores Out of 8)
The IB Middle Years Programme (MYP) uses a distinctive grading system that can feel unfamiliar at first—especially for families used to percentages or letter grades. Final grades are reported on a 1–7 scale, but throughout the year students often receive scores out of 8 on individual criteria. This difference is intentional and central to how the MYP measures learning.
In this guide, you’ll learn how MYP grade boundaries work, why assessments are scored out of 8 during the course, and how teachers arrive at the final 1–7 grade. Understanding this system helps students focus on growth, feedback, and mastery—rather than chasing points.
The Philosophy Behind the MYP Grading System
The MYP is built on a criterion-related approach to assessment. Students are not ranked against classmates and grades are not curved. Instead, performance is measured against clearly defined objectives that describe what understanding and skills look like at different levels.
This philosophy ensures that:
Students are assessed against transparent standards, not peers
Grades reflect quality of learning, not competition
Feedback drives improvement and reflection
This approach aligns with the core values of the International Baccalaureate: inquiry, independence, and critical thinking.
How the MYP 1–7 Scale Works (and Where the 0–8 Scores Fit In)
During the Course: Scores Out of 8
Each MYP subject is assessed using four criteria (A–D). Each criterion is scored on a 0–8 scale based on descriptors that define increasing levels of achievement.
Grade 3 (10–14): Developing knowledge and partial success
Grade 4 (15–18): Satisfactory achievement; meets most objectives
Grade 5 (19–23): Strong, consistent understanding and application
Grade 6 (24–27): High-quality work with depth and analysis
Grade 7 (28–32): Excellent mastery; independent and insightful
Every MYP subject—whether Sciences, Mathematics, Languages, or the Arts—uses this same structure, even though the criteria assess different skills.
What Each Final Grade Represents
Grades 1–2: Emerging Learner
Understanding is limited and support is frequently needed. Students are beginning to grasp key concepts but struggle to apply them independently.
Grades 3–4: Developing Learner
Students show growing comprehension and can apply ideas in familiar contexts. A 4 is a solid, respectable achievement in the MYP.
Grade 5: Competent Learner
Students demonstrate strong understanding, clear communication, and effective application across contexts.
Grades 6–7: Proficient to Excellent Learner
Work shows independence, accuracy, creativity, and critical insight. Students consistently exceed basic expectations.
How Teachers Determine Final Grades
Final MYP grades are never based on a single test. Teachers use a wide range of evidence, such as:
Projects and written tasks
Investigations, experiments, or research reports
Oral presentations and discussions
Creative work or performances
Reflections and portfolios
Each task aligns with specific criteria, ensuring fairness and consistency. Teachers then apply professional judgment to decide the best-fit level for each criterion at the end of the period.
Formative vs Summative Assessment in the MYP
The MYP uses both to support learning:
Formative assessment: Practice tasks and drafts used for feedback (not final grading)
Summative assessment: End-of-unit tasks that provide evidence for criterion levels
Formative work helps students improve; summative work contributes to the final grade.
The Central Role of Feedback
Unlike percentage systems, the MYP emphasizes descriptive feedback. Students learn:
What they are doing well
What needs improvement
What “the next level” looks like
This feedback-driven cycle helps students take ownership of learning—one of the MYP’s defining goals.
Common Myths About the MYP 1–7 Scale
Myth 1: A 4 is a low grade In MYP terms, a 4 indicates satisfactory achievement and meeting expectations.
Myth 2: Students are graded on a curve False. MYP grading is criteria-based, not comparative.
Myth 3: Scores out of 8 are final grades They are not. Scores out of 8 apply to individual criteria, while final grades are always out of 7.
How Students Can Improve MYP Grades
Study the criteria before starting tasks
Use feedback to target the next achievement level
Reflect after each assessment
Manage time across subjects to avoid rushed work
Embrace inquiry rather than aiming for perfection
Progress in the MYP is about learning how to improve, not just collecting marks.
Conclusion
The IB MYP grading system is designed to value growth, understanding, and reflection. While students are assessed on criteria scored out of 8 during the course, their overall achievement is ultimately reported on a 1–7 scale that reflects holistic performance.
By focusing on feedback, criteria, and continuous improvement, the MYP helps students develop skills that matter far beyond grades: curiosity, resilience, and a genuine love of learning.
