Title: Off-grade usage of numeracy items: Investigating item invariance using a step-wise procedure

Abstract: The study being presented is part of the project "A Scale for Numeracy", where we aim to vertically scale the Norwegian national tests in numeracy for grade 5 and grade 8. In the design used to build the vertical scale, numeracy items are used off-grade, both in higher and lower grades. The study presented investigates if the 5th and 8th grade items behave invariant when administered in grades 6 and 7.
