SACMEQ IV Study OUTCOME MEASURES
Assessment domain(s)
- Mathematical literacy/Mathematics/Numeracy
- Reading/Reading literacy
- Others: HIV/AIDS and TB knowledge
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
- TBKT levels – grade 6 pupils and their teachers – in South Africa only
Questionnaire and background scales
Scale Creation
- Indices were compiled to summarize responses to the background survey questions put to pupils, teachers, and school heads.
- The computation of these indices followed the same development process as the test scores (item response theory, the Rasch partial credit model).
- To facilitate interpretation of the indices, 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
- Home condition indices (roof, wall, floor)
- Socio-economic status index
- Lighting source index
