Speech, reading, and writing are the basic forms of linguistic communication. Therefore, it is very important to diagnose any problems with them as early and completely as possible, particularly in children with special needs. One of the methods that focuses primarily on the diagnosis and therapy of such learning difficulties is the one developed by Fred Warnke. The diagnostic solutions of the method were motivated by the following assumptions: (a) Automation of hearing, vision, and motor functions can be improved based on the level of brain activity; (b) the development and automation of phonological analysis and synthesis are based on cooperation between the two brain hemispheres. The main purpose of this paper is to present and discuss some research results that show the usefulness of diagnosis of the first stage of the Warnke method, as well as the training determined by it, in improving the phonological memory, language, and reading and writing skills of a group of four Polish children with special needs. The range of automation of each function was estimated on the basis of the values obtained in the diagnoses (initial and final). The final diagnosis showed an improvement in the levels of speech, reading, and writing. Thus, the research has confirmed that the Warnke method diagnosis may help to broaden and complement the standard evaluation methods of phonological competence for Polish children with special needs. The outcomes were so encouraging that we decided to present them to a wider audience.
