The phonological awareness, understood as the ability of reflection and manipulation of speech sounds, is related to succeeding in the written language acquisition process. This research aimed at evaluating the effectiveness of an intervention program to develop metaphonological skills and aid the learning of writing for Brazilian Portuguese-speaking children. A total of 90 children between 5 and 6 years old who attended the literacy classes participated in this research. A quasi-experimental design was used in three steps: pre-test, intervention and post-test, with the application of exams to the children. The results showed that the metaphonological skills have an aiding role at the beginning of the written language acquisition process, and that they can be developed through intervention programs in different application conditions.
