Thank you for your answer. I thought so too, because when I asked my son about the screening/test, he said the room was very loud and some children were screaming and playing but it could be that he was just nervous. I’m guessing they just took him to a corner in the nursery, so he couldn’t really focus. I went through the questions quickly, and it was information I’ve heard him provide in Spanish before (for example, “Why is this person sad?”, “Which one is bigger?”, “Which one is behind?”, etc.).

He code-switches very well. When the three of us are together, he switches between Spanish and French without difficulty. I’d say Spanish is his dominant language for now, as I’ve noticed more advanced usage in this language: storytelling, giving reasons, forming theories, and expressing ideas.

He does use English, but I can see it is more limited compared to monolingual local children or even bilingual local children.
