IB MYP Grading Scale (2026 Complete Guide)

Parents moving into the IB Middle Years Programme often hit the same wall: their child comes home with a report card showing scores like “Criterion A: 6/8” and a final subject grade of “5,” and neither number means what a percentage or a letter grade would mean back home. This guide breaks down exactly how MYP grading works — the scale, the four assessment criteria, how the final 1–7 grade gets calculated, and how it compares to GCSE and the IB Diploma — so you can read your child's report with confidence.

Quick Answer

The MYP grades every subject on a scale of 1 to 7, where 7 is the highest. Each subject is assessed against four criteria (A–D), each marked out of 8. The four scores are added together for a total out of 32, and that total is converted into the final 1–7 grade using published grade boundaries. It is a criterion-based system — your child is measured against fixed performance descriptors, not ranked against classmates.

What Is the IB MYP?

The Middle Years Programme is the second stage of the IB continuum, designed for students aged 11 to 16 (roughly Grades 6 to 10). It sits between the Primary Years Programme and the IB Diploma Programme, and its job is to build the research, inquiry, and critical-thinking habits that the Diploma will later demand.

Unlike GCSE or many national curricula, the MYP doesn't grade students through a single end-of-year exam. Instead, teachers collect evidence across the year — essays, projects, lab reports, presentations, tests — and judge that evidence against published criteria for each subject group.

Why the Grading System Matters

The MYP grading system matters because it's unfamiliar to most parents outside the IB world, and unfamiliar systems create unnecessary anxiety. A “5” on an MYP report can look unimpressive next to a childhood memory of grading on a percentage scale, when in reality a 5 usually reflects solid, consistent performance. Understanding the mechanics — what each grade means, how criteria are scored, and how the final number is calculated — removes the guesswork and lets you have a more useful conversation with your child's teachers.

It also matters academically. MYP performance shapes subject choices going into the Diploma Programme, and the habits the criteria reward — evidence-based reasoning, reflection, clear communication — are the exact habits DP assessment rewards two years later.

The MYP Grading Scale: Grades 1–7 Explained

Every MYP subject receives a single final grade from 1 to 7 at the end of each reporting period. Here's what each grade generally represents:

A useful way to think about it: grades 6–7 represent mastery, 4–5 represent solid competence, and 1–3 signal that a student needs targeted support. Because the system is criterion-referenced rather than norm-referenced, a student's grade doesn't depend on how classmates performed — it depends only on how their work matches the published descriptors.

Assessment Criteria: How Each Subject Is Actually Marked

This is the part most parents find confusing, so it's worth slowing down here. Every MYP subject group has four assessment criteria, labelled A, B, C, and D. Each criterion is marked out of 8 points, using a rubric called a level descriptor that describes what performance looks like at each achievement band (typically 0–1, 2–3, 4–5, 6–7, 8).

The exact meaning of each criterion changes by subject group, but the general pattern looks like this:

• Criterion A — Knowledge and understanding (or “Investigating,” depending on the subject)
• Criterion B — Applying knowledge, planning, or organizing
• Criterion C — Communicating results, producing texts, or evaluating
• Criterion D — Reflecting, thinking critically, or applying skills in new contexts

For example, in Sciences, Criterion A is “Knowing and understanding” and Criterion D is “Reflecting on the impacts of science.” In Language and Literature, the criteria shift to Analysing, Organising, Producing texts, and Using language. The labels change, but the structure — four skills, each scored 0–8 — stays consistent across every subject.

Teachers don't average scores across the year. They use a “best-fit” approach: they gather evidence from multiple tasks, look at the trend in a student's performance over time, and assign the level that best matches the body of work — with more recent, more complex evidence usually carrying more weight than an early attempt.

How Final Grades Are Calculated

Once a student has a level for each of the four criteria, calculating the final grade is straightforward:

Step 1: Add the four criterion levels together (each out of 8, so the maximum total is 32).

Step 2: Convert that total into a final 1–7 grade using the grade boundary table (below).

Grade Boundaries Table

These are the general MYP grade boundaries commonly applied across the total criterion score (out of 32). Individual schools set their own internal boundaries within the IB's framework, and the IB publishes separate, subject-specific boundaries each session for optional on-screen eAssessment — so always check your own school's assessment policy for the exact figures they use.

Notice how the bands widen slightly as scores drop — this reflects the fact that distinguishing between a 6 and a 7 requires much finer judgment than distinguishing between a 1 and a 2.

Subject-Wise Grading: The Same Structure, Different Content

Every MYP subject group — Language Acquisition, Language and Literature, Individuals and Societies, Sciences, Mathematics, Arts, Physical and Health Education, and Design — is assessed using four criteria scored out of 8, totalling 32, converting to the 1–7 scale described above. What changes between subjects is what each criterion measures.

In Mathematics, for instance, Criterion D typically asks students to apply mathematics in real-life contexts, while in the Arts, Criterion D usually focuses on responding and reflecting on artistic process. This consistency is deliberate — it means a Grade 9 student moving from Science to Individuals and Societies is still working within a familiar assessment logic, even though the content is completely different.

The one subject that breaks this pattern slightly is the Personal Project, completed in the final year of MYP. It's assessed against its own set of criteria focused on planning, applying skills, and reflecting, and students need at least a 3 out of 7 on the project to be eligible for the MYP certificate.

MYP vs DP Grading: What Changes at the Diploma Level

Families often assume MYP grading and IB Diploma Programme (DP) grading are identical because both use a 1–7 scale. They share the same range, but the mechanics differ in important ways.

The key difference for families to understand: MYP grades are a developmental signal, not a university-facing credential. DP grades, by contrast, go straight onto transcripts that universities evaluate. This is why MYP performance is worth taking seriously, but a 5 in MYP Chemistry doesn't carry the weight a 5 in DP Chemistry HL does.

MYP vs GCSE: Two Very Different Philosophies

Neither system is objectively “harder” — they measure different things. GCSE rewards precision under exam pressure and deep specification knowledge. MYP rewards sustained, evidence-based thinking developed over months. Students who are strong exam-takers but weak at long-form reflective work sometimes find MYP's criteria — particularly Criterion D-style reflection — more demanding than they expected. Students who dislike single high-pressure exams often find MYP's continuous assessment style more forgiving.

Tips to Score a 7 in MYP

A few patterns show up consistently in strong MYP performance:

• Study the criterion descriptors before starting a task, not after. Students who read the 6–7 band description before writing know exactly what “sophisticated” or “nuanced” looks like for that assignment.
• Treat feedback as data, not a verdict. The best-fit model rewards improvement across tasks — a weak first draft followed by clear growth often scores better than late, unaddressed feedback.
• Practise reflection deliberately. Criterion D-type reflection is where many otherwise strong students lose marks, because it asks for genuine evaluation of their own thinking, not a summary of what they did.
• Apply skills to unfamiliar contexts. The top band consistently asks whether a student can transfer understanding to a new situation — not just repeat what was taught in class.
• Keep evidence organized across the term. Because grades reflect a body of work rather than one test, students who track their own progress across tasks can identify — and fix — a weak criterion before the reporting period ends.

Where a student's gap sits in one specific criterion rather than the whole subject, targeted, criterion-focused practice with a tutor familiar with MYP rubrics tends to close that gap faster than general subject revision.

Frequently Asked Questions

Conclusion

The MYP grading scale can look intimidating on a report card, but the logic behind it is simple once it's unpacked: four skills, each scored out of 8, added up and converted to a single 1–7 grade. What makes the system genuinely useful — for parents and for the student — is that a low grade always points to a specific, nameable skill gap rather than a vague sense of “not doing well.” That specificity is what makes targeted support effective.

If your child is working through a criterion consistently below their overall level, a tutor who understands MYP rubrics can focus practice exactly where it's needed rather than re-teaching content the student already knows. The Gurukul Global's IB-trained tutors work directly with the MYP criteria your child's school uses, across all eight subject groups.
