Signs of reading and writing difficulties can often be diagnosed in preschool children and at the beginning of the first grade. Educators and teachers should determine during this sensitive phase whether and what learning problems a child has and how they can optimally support them. Teachers need diagnostic tools for early detection that are time-efficient. The group test by Barth and Gomm provides the right material for this purpose. The test allows for a quick assessment of whether children can recognize rhymes, identify the initial or final sounds of a word, and determine the syllables of a word. In short, it assesses the extent to which children's phonological awareness is developed, which is a significant precursor skill for literacy acquisition. The test manual for adults offers background information.
