Each PISA data collection effort assesses one of the three subject areas in depth (considered the major subject area), although all three are assessed in each cycle (the other two subjects are considered minor subject areas for that assessment year). Assessing all three areas allows participating countries to have an ongoing source of achievement data in every subject area while rotating one area as the main focus over the years. In the fourth cycle of PISA, reading was the subject area assessed in depth, as it was in 2000.
