Field notes
Pages from the drawing table, not advice for every school at once.
These notes record decisions we keep making: where a bar should start, what to pull from the cupboard, how many sheets a staff-room wall can hold.
Ruling a mathematics band so the year head can see the middle
How a mathematics score band is ruled for a Thai secondary year group so the middle of the cohort is visible before the staff meeting.
What to pull from the cupboard before an O-NET afternoon
A practical list of mark sheets and old chart books to gather before a school sits down with its O-NET scores.
Four subjects is enough for a staff-room wall
Why a staff-room wall chart of school examination results should stop at four subjects, and how long the sheets should stay up.
When the top of the cohort is thin and the middle is wide
Reading a school examination cohort whose high scores are few and whose middle band is broad, without turning the chart into a verdict on the class.
