Compare And Contrast The Customary Age Of Mastery

The customary age of production and the age of mastery are both similar and different in their own ways. First, let us define them and work from that starting point. The customary age of production is “the age by which 50% of all children can produce a given sound in multiple positions in words in an adultlike way.” The age of mastery is “the age by which most children produce a sound in an adultlike manner.”
These terms are similar in that they both focus on when the child can produce adultlike sounds. Furthermore, according to the reading this week, they are both “the most popular set of norms for phoneme attainment.” The book continues to state that they are credited to Sander. Thus, these ages of phonetic development are similar in many ways.
Te customary age of production is a stricter measurement because it requires the child to be able to produce a sound in different situations. In order to reach the customary age of production, they need to be able to include a sound, such as /t/, in numerous settings. For example, it should be accomplished in the initial, medial, and final position of words. Furthermore, they should be able to use it when it is placed within relation to other sounds. This enables the practitioners to gauge how well a child can produce a sound in isolation. The age of mastery does not necessarily have this requirement. This is obvious difference between the
