From 2012 First Half survey cycle to 2015 First Half survey cycle, coursework units offered by ACU were evaluated using the SEU questionnaire. The SEU questionnaire was designed to collect student feedback on various aspects of learning and teaching quality at the unit level.
From 2012 Second Half survey cycle to 2015 First Half survey cycle, some lecturers/tutors used the SET questionnaire to gather student feedback on various aspects of the participating staff member's teaching.
Key aspects of SEU and SET instruments have been combined to form the SELT questionnaire. From 2015 Second Half cycle onwards, the SELT survey replaces SEU and SET surveys, for the evaluation of ACU coursework unit/teaching.
