A review of the research literature indicated that there were probable orders in which students develop understandings and skills for calculating with percentages. Such calculations might include using models to represent percentages, knowing fraction equivalents, selection of strategies to solve problems and determination of percentage change. To further describe the hierarchies, an assessment instrument was constructed and piloted before being refined and trialled with lower secondary students. Rasch model analysis was applied to the results.
