Teachers were asked to indicate the proportion of their students they believed were experiencing specific difficulties. The response choices were percentage brackets: ‘0%–20%’, ’21%–40%’, ’41%–60%’, ‘61%–80%’, or ’81%–100%’. Percentage brackets were used so that teachers could more easily report how many students were experiencing difficulties, but they are broad groups. All responses in these percentage brackets were combined and used to calculate averages that could show more detail than, for example, ‘0–20%’.

The average proportions of students that teachers considered were showing signs of these difficulties by year level are shown in Table TT2.5.
