Moderation of SBA Scores
To ensure the reliability and comparability of assessment standards across schools, the HKEAA moderates SBA marks submitted by different schools, either through statistical moderation or expert judgment. For most subjects, the moderation is conducted by statistical adjustments supplemented with sample review of students’ work.

The HKEAA employs appropriate methods for moderating the raw SBA scores submitted by different schools, with the following aims:

  • to maintain comparability of SBA results across schools, and thus ensure fairness for individual students and schools;
  • to maintain the quality, reliability, and validity of SBA from year to year; and
  • to gather information that may be useful for making recommendations for improved practice (feedback to schools).
