Tailoring a measurement model of socioeconomic status: Applying the alignment optimization method to 15 years of PISA

Abstract This study aims to examine one of the key contextual constructs measured in ILSAs, socioeconomic status, within a single national context. Using PISA data from Sweden, this investigates whether items used indicate status can be create construct that is applicable multiple cycles Sweden. MI testing 2000 CFA solution across all demonstrates invariance at metric level. Once alignment optimization method was applied measurement model, fell thresholds for acceptable non-invariance. Therefore, posits retained questionnaire since tailor model SES
