What's the advantage of being I first grade all day? I would look at the question from that perspective.
My eldest went to a dual immersion school. The kindergarten focused more on learning to count and basics, whereas the first grade was much more academic. Personally, I would look at the Spanish curriculum in both grades and try to aim for the one he'd benefit from the most.
How do they split their time in each grade? At my son's school, kindergarten was only 20% English, in order to spend as much time on the new language as possible. The split in grade 1 was 40% English and 60% the other language. If this school is similar, they may be trying to provide as much Spanish immersion as possible while realizing that he'll be fine moving to grade 2 English and hoping that he'll catch up in Spanish.
Also, what's the plan for year 2? Are they planning on putting him in grade 2 all day?
