Figure 5-2. Average subscale scores of 15-year-old students in reading literacy, by country: 2009
1 The access-and-retrieve subscale involves finding, selecting, and collecting information.
2 The integrate-and-interpret subscale involves processing what is read to make internal sense of a text.
3 The reflect-and-evaluate subscale involves drawing on knowledge, ideas, or values external to the text.
NOTE: The average scale score in reading literacy is made up of all the items in the three subscales. However, the average scale score and the three subscales are computed separately through item response theory models. Therefore, the average scale score is not the average of the three subscale scores.
