The efficiency of feedback content has received much attention in prior feedback research, but students' feedback perceptions have hardly been studied. A structural validation was conducted of a feedback perceptions questionnaire amongst 1535 secondary education students. The structural validity of the scales was confirmed: fairness (FA), usefulness (US) and acceptance (AC) constitute the joined component 'Perceived Adequacy of Feedback' (PAF), which in turn positively predicts willingness to improve (WI) and affect (AF).
