Objective: To evaluate the psychometric properties of the Shortened Version of the Token Test (SVTT), the Peabody Picture Vocabulary Test (PPVT-III), and the Rey-Osterrieth Complex Figure (ROCF) using an item response theory (IRT) framework and to establish normative data for Waranka children and adolescents based on their ability scores.

Methods: A total of 436 healthy people aged between 6 and 17 participated in this study. The factor structure was evaluated using confirmatory factor analysis (CFA) and the difficulty and discrimination parameters using IRT through the two-parameter logistic model for the SVTT and PPTV-III, while for the ROCF, the graded response model was used.

To generate normative data (ND) for executive functions tests in the Waranka minority population of Ecuador. Four-hundred participants aged 6-17 completed the Symbol-Digit Modalities Test (SDMT), Trail-Making Test (TMT), Modified-Wisconsin Card Sorting Test (M-WCST), and Test of Colors-Words (STROOP). Scores were normed using multiple linear regressions, including age, age, natural logarithm of mean parent education (MPE), sex, bilingualism, and two-way interactions as predictors.
