When DD was in her first year of kindergarten (we start at 4 here and do 2 years), her vocabulary test came back with a very low score. I told them, "Well, you are only testing HALF of her vocabulary because you only test Dutch, and she also speaks English." If they had tested both, I'm sure she would have been above average. But, they don't make allowances for bilingual kids. So they enrolled her in this special class of 10 kids who needed extra help with language. Shortly after they did that, there was this article that came out about research of bilingual children. It said that children who are raised in a home with more than one native language start out with a delay in the vocab area when they start school, but they usually catch up quickly and then end up far exceeding their single-language peers. Sure enough, by the end of that school year, she was average on vocabulary and didn't actually qualify for that class anymore, but they had already enrolled her. So normally, if you start with the class, they have to go for the entire 2nd year of kindergarten, but because DD didn't even qualify anymore, they made us a deal that she only had to do a half year, and then if her test scores were average or higher, she could stop with the class. She scored above average and the teacher of the special class was so glad, because she didn't know what to do with DD. She told me DD was head and shoulders above the rest of the class and she could do the hardest work the teacher had faster than the others could do the EASIEST work...she didn't understand why DD was even in the class to begin with because she obviously didn't need it, when there were other kids who might have, but they could only take 10 kids. So she stopped going to that class and she is still off the charts above average in all the language things. She reads at high school level, she scores in the top probably 5% at least, and that's throughout the nation. So that article was bang on. It also said that for some reason, growing up in a bi-lingual household gives some sort of natural protection against dementia, because the part of the brain used for language is stimulated in a particular way with multi-languages, and by turning on that part of the brain, it suppresses things with Dementia or something...Really fascinating. But both my kids do really well in school, and a lot of that could be attributed to speaking 2 languages from birth, according to this study. Whatever it is, I'm glad my kids benefit from it.
