When children's sounds develop.
Below are the developmental age norms for sound development via the American Speech-Language Hearing Association:
*Age 3 ( p, m, w, b, d)
*Age 3 1/2 ( n, k, g, t, f)
*Age 4 (y)
*Age 5 (l)
*Age 5 1/2 (v)
*Age 6 1/2 (ch, sh)
*Age 7 (j)
*Age 8 (s, z, th, r)
This explains when 90% of children should have mastered the sounds listed. If the child has not mastered the sound by the end of the age listed, they will be screened for speech-language support. Language referrals can be made by the speech pathologist, classroom teacher, parent or other educational staff.
**A child with a lateral production of sound can be assessed at an earlier age.
**A child with dental structure that prevents successful articulation therapy is not eligible for speech.
**Students with sound errors/phonological processing errors that are consistent with normal development are not eligible for speech services.
