Why This Matters

You're staying late again — this time to reformat a unit planner document for the third time because the school added a new field to the template. Meanwhile, you skipped writing rubric-aligned feedback on last week's essays because nobody explicitly told you it mattered, and now a parent is asking why their child's grade doesn't seem to reflect the criteria the school promotes on its website.

This is what role ambiguity does: it makes you exhausted from doing things nobody actually needed, while quietly missing things that genuinely mattered. Nobody handed you a clean job description when you signed on to teach MYP. This article is that job description — written honestly, including the parts that are genuinely optional.

Understand the Idea

Think of your MYP responsibilities in four groups: planning, teaching, assessing, and collaborating.

In planning, you function as a designer, not just a deliverer of pre-made content. This means you make real decisions — which key concept fits this content best, what the statement of inquiry says, what the summative task requires — rather than simply following a script handed down from above. In many schools this design work happens partly through collaborative planning: scheduled time, often built into the timetable, where teachers of the same subject or same grade level plan units together rather than alone. This isn't a nice-to-have add-on meeting; in most MYP schools it's where a meaningful share of real unit-design work happens.

In teaching, your responsibility includes explicitly building ATL (Approaches to Learning) — transferable skills like research, communication, self-management, and collaboration — into your lessons, rather than assuming students already arrive with them. This doesn't mean a separate "skills lesson" bolted onto content; it means naming and practicing the skill inside the content lesson itself. If students are researching causes of a historical event, that's also the moment to explicitly teach and check research skills, not just historical content.

In assessing, you act as an assessor against criteria: judging student work using your subject's assessment criteria and level descriptors, rather than assigning a single overall percentage from your own private scale. This is a genuinely different skill from traditional grading, and it takes deliberate practice to apply consistently — most new MYP teachers underestimate how much calibration this requires.

Finally, reflection as professional practice means MYP expects some form of ongoing reflection on your teaching and your units — not just at report card time, but built into how units close, often shared with your planning team. This is less a bureaucratic requirement and more a genuine mechanism for units to actually improve year over year, rather than being re-taught identically out of habit.

What is not automatically your job: designing the school's assessment policy, running moderation meetings (an MYP subject group coordinator or head of department typically leads this), managing the whole-school reporting platform, or single-handedly deciding how global contexts are distributed across grade levels — that's usually a coordinated, whole-department decision. If you're doing any of these alone with no support, that's a local school gap, not an MYP requirement.

See It in Practice

Here's a plausible "week in the life" of an MYP subject teacher at a mid-sized international school — invented but realistic, useful for seeing where MYP-specific time actually goes versus general teaching time.

Monday: Regular teaching load, five periods. One planning period used for marking, not MYP-specific.

Tuesday: 40-minute collaborative planning meeting after school with two other Grade 8 Science teachers, refining the summative task rubric for the unit starting in three weeks. This is MYP-specific time — the meeting exists because units are designed together, not solely alone.

Wednesday: Regular teaching. During one lesson, the teacher explicitly pauses to name the ATL skill students are using ("this is organization skills — notice how you're sequencing your lab write-up") before returning to content. Two minutes, MYP-specific, embedded rather than separate.

Thursday: One hour after school spent applying the assessment criteria to a stack of summative tasks — genuinely slower than the teacher's old "read and assign a percentage" method, because each piece is checked against multiple criteria strands rather than judged holistically. This is real MYP-specific assessment time, and new teachers consistently underestimate how much longer it takes in year one.

Friday: Department meeting, partly whole-school business, partly a short moderation discussion — two teachers compare how they scored a borderline piece of student work against the criteria, to keep their judgments consistent with each other. This moderation work is coordinated by the department, not something the individual teacher owns alone.

Contrast — a teacher misreading their role: spending Tuesday's collaborative planning time reformatting the unit planner document's fonts and colors, because it "needs to look right," while the actual statement of inquiry and summative task get five rushed minutes at the end. The time went to something that felt like MYP work but wasn't the part that mattered.

⚠️ Common trap: Confusing "the paperwork looks complete" with "the planning is done." A beautifully formatted unit planner with a vague statement of inquiry is worse than a plain document with a sharp one.

Apply It

List your five biggest time costs from a typical week — be specific and honest, including things that feel MYP-adjacent but might not actually be required by the programme itself. For each, mark whether it's a genuine MYP-related responsibility (planning as designer, embedding ATL, assessing against criteria, collaborative planning, reflection) or a local/school habit (a particular software's formatting quirks, an extra meeting your school added, a personal perfectionism about document appearance).

🧭 Planning decision: Write this list into your planner or notes as two columns: "Genuine MYP time" and "Local habit time." For anything landing in "local habit," decide — this week — one thing you'll either simplify, delegate, or drop. That's your concrete output from this activity: not a reflection, a decision you'll act on.

If most of your time is landing in "local habit," that's worth raising with your coordinator directly — it's a solvable problem, not a personal failing.

Avoid This

Symptom: you're spending hours on template formatting instead of the statement of inquiry itself. Fix: separate the thinking work from the document work; do the thinking first on paper or in a notes app, then transfer to the template last.

Symptom: you're assessing everything holistically with a single grade, skipping the criteria strands. Fix: physically separate your marking into passes — one pass per criterion strand, at least until judging against multiple criteria at once becomes automatic.

Symptom: you avoid collaborative planning time because it feels like "just talking." Fix: bring a concrete draft (even rough) to every planning meeting so the time produces a decision, not just discussion.

Symptom: you assume moderation and reporting-platform administration are your job alone. Fix: check with your coordinator — these are typically shared or coordinator-led responsibilities.

Check Yourself

  • Can you name one task from your current week that belongs in "genuine MYP responsibility" and one that's a local school habit?
  • Do you know who leads moderation at your school — you individually, or your department/coordinator?
  • Have you identified, this week, one specific piece of local-habit time you're going to cut or simplify?
