Part 1, done

Focus and rationale

Schools can run several development plans; one completed plan is shared with the IB in the self-study.

The question

How might we make internal marking consistent across subjects, so predicted grades become a guide students can trust?

Where we are

In the last session on file, 15 of 22 predicted grades were within one grade of the final result. Teachers mark alone, and nobody has agreed the standard across MYP 5 and DP 1.

Where we want to be

By May 2028, at least 4 in 5 predicted grades are within one grade of the final result, in every subject group.

Why it matters

Students and universities rely on predicted grades, and feedback only helps when the standard behind it is shared.

Who leads it

Anna Vester leads it, with Helen Okonkwo and Marco Ellison

Part of school priority 1: The same work gets the same grade, whoever marks it, in MYP and DP.

Part 2, needs you

Impact on students

Predicted grades within one grade of the final result

68%, 15 of 22. Aim: 80% by May 2028

Next reading: mock results against predictions, February 2027.

Two teachers marking the same sample agree within one band

No reading yet. The first is the TOK exhibition internal standardisation.

Part 5

Understanding and application

Not written yet. What to consider next: Who agrees the standard across programmes, and who can overrule a teacher's grade? The priority this plan serves: The same work gets the same grade, whoever marks it, in MYP and DP.

Action, Waiting on Jonas, starts Wed 11 Nov

One joint MYP 5–DP 1 standardisation cycle in every subject group

Owner: Marco Ellison, MYP coordinator.

This cycle is waiting on who agrees the standard across programmes. It has not started.

Open the decision

Needs a decision

Who agrees the standard across programmes, and who can overrule a teacher's grade?

Raised 12 May. Named on 12 May, 9 Jun and 25 Aug. Not decided. 7 SLT meetings are on the record. 3 of them named the disagreement. None closed it.

Opened 12 May 2026, 162 days open

The joint MYP 5 and DP 1 standardisation cycle in this plan is waiting on it. With Jonas Berg, head of school.

Before Jonas decides

What Harbour already says Teachers in the DP mark the same work together before predicted grades are sent.
What the research says One source on comparative judgement for non-exam assessment. It does not say how a small department should run it. Cambridge Assessment, comparative judgement for non-exam assessment
What Harbour decided before Raised 12 May. Named on 12 May, 9 Jun and 25 Aug. Not decided.
A move to try Name one owner for the standard, and write down what they may overrule.
Check in six weeks Do two teachers' marks on the same sample agree within one band?
