Answer: The student questionnaires are administered to learners at school after they have completed the mathematics and science assessments. The teacher and school questionnaires are completed by the mathematics and science teachers, and the school principals during the testing time for the learners. These are then collected by the test administrators before they leave the school. The home questionnaire, introduced in 2015, was sent home with learners before the day of testing and learners were required to return the completed questionnaires on the day of assessment.
