test for children?

[Hiromi Muranaka]

Dear all,

I am conducting research on the Japanese narrative acquisition of bilingual
children. My participants include pre-school and school children aged 4-5
and 8-9. Does anyone know whether there are vocabulary or grammar tests for
children in Japanese in order to test whether the children are language
impaired or not?

Thank you for your attention.

Regards,
Hiromi
