Some therapists specialise in working with children from multicultural backgrounds where English is an additional language. Such children may have difficulties learning the language spoken at home as well as English. A therapist will not see them unless they are having problems in both their first language and English. The therapist will need to ascertain the level of the child's difficulties in the first language by gathering information from the parents and the child, often using interpreters or co-workers. If children have a problem in their first language as well as in learning English, then the speech and language therapist will work with the families to help the children develop the underlying skills necessary for language learning.
