Challenges in BILINGUAL Assessment

Second language learning looks like DLD
First language loss looks like DLD
Language Dominance
Age of first English exposure
Percent of current exposure
Test domain (by language experience)

Best Results when we test in BOTH

Experience in English

Child’s level of experience in English
Age of first exposure
Current exposure
What we test

Experience in the L2

1 year experience
30% or more exposure
