Achievement and test scales
Scale creation
  • An international reading performance scale and an international mathematics performance scale were constructed using item response theory (Rasch partial credit model).
  • For both scales, the international average is 500 points and the standard deviation is 100 points, with all countries being given equal weighting.
  • There are eight competency levels for both reading and mathematics tests.
  • Minimum and desired knowledge levels were developed for the HAK test.
 
List of achievement scales
  • Reading, mathematics, and HAKT achievement scores – Grade 6 pupils and their teachers
  • Reading competency scale – Grade 6 pupils and their teachers
  • Mathematics competency scale – Grade 6 pupils and their teachers
  • HAKT levels – Grade 6 pupils and their teachers

Questionnaire and background scales
SCALE CREATION
  • Indexes were compiled to summarize responses to the background survey questions put to pupils, teachers, and school heads.
  • The computation of these indexes followed the same development process as the test scores (item response theory, the Rasch partial credit model)
  • To facilitate interpretation of the indexes, results were adjusted to an international scale for which the average is 50 and the standard deviation is 10.
 
LIST OF BACKGROUND SCALES
  • School infrastructure index
  • Classroom equipment index
  • Personal possessions index
  • Academic qualifications index
