Supplement S1: Financial literacy changes among rural and urban Colombian adolescents

Supplementary material for the article “Financial literacy changes among rural and urban Colombian adolescents,” accepted for publication in the International Journal of Evaluation and Research in Education (IJERE). This supplement documents the methodological and statistical analyses supporting a retrospective single-group pretest and posttest evaluation of a nine-workshop financial education program delivered in 2022 in rural and urban Colombian secondary schools. It reports the scoring keys for the 12-item objective financial knowledge battery (K12); the specification of the linear mixed-effects model and the school-clustered change regression; complete item-level results with Holm adjustment for all 21 retained items; missingness and internal consistency diagnostics; sensitivity analyses covering alternative scoring rules, record linkage, recorded timestamp intervals, baseline-conditional models, and ceiling frequencies; the record linkage reconciliation audit; and the institutional authorization and data governance statement. The analyses use a verified panel of 481 matched student pairs from 27 schools. Raw institutional records containing student identifiers are not publicly shared.
