Objective. This study sought to characterize the psychometric properties of the Preschool Language Scale - 3 (PLS-3) using a sample of 477 Colombian children between the ages of 4 and 7 from the city of Bogotá, D.C. Method. To achieve this, analyses of discrimination coefficients, difficulty and the tetrachoric relations matrix were carried out. Results. Appropriate levels of reliability, high sensitivity to the evolution of comprehension and linguistic production of the children as well as low indices of difficulty in some reagents were found. Conclusion. These results are discussed in the light of discrimination indices in tests of typical and atypical linguistic development.
