    Language is mankind’s most used system as means of expression. To evaluate language development some standardized tests are required, but many of those are from foreign countries and must be validated; therefore, there is an interest in evaluate diagnostic features of Alfa scale in Colombian population. It was made an evaluation study on diagnostic technologies with transversal sampling, on 77 students ages 3 to 17 from randomly chosen schools. The inclusion and exclusion criteria were selected according to guidelines for the application of the scale. To develop this study, informed consent was obtained from the students’ parents. A descriptive analysis, criteria validation and reproducibility among Alpha scale methods with regards to the application of a linguistic evaluation protocol are shown. In this work, Alfa scale showed sensitivity up to 31.8% and specificity up to 57.9%. The reproducibility between the scale and the speech language evaluation for verbal expression presented a kappa of 0.36 (CI 95% 0.18 – 0.54). As a conclusion, Alfa scale’s diagnostic features in studied sample didn’t show a good performance. It is necessary to develop adaptations in vocabulary and syntactic structures to carry out the test in Colombia.
