I recall taking the Terra Nova "tests" along with a myriad of other useless and time-consuming "tests" when in elementary school. In high school we had the New York State Regents exams. When I was in school you were not required to get a Regents diploma, but you are now. But instead of holding every student to a higher standard, they just lowered the passing grade. And Regents exams just aren't for everyone. If you don't plan on going to college, and you plan to attend a vocational school or just get a job, there's no reason to get a Regents diploma. It's a lot of unnecessary work that some people just aren't going to be able to do. It isn't a matter of intelligence, either. And since Regents are just a New York (and I think California) thing, most colleges don't care one bit about whether you passed the Regents or not.
I took the "Math A" Regents three times, and scored a 17, 63, and 42, respectively. I would've needed a 65 to pass. I wasn't required to get a Regents diploma, so it didn't really matter. And I ended up leaving public school to homeschool anyhow. But it scares me to know that there are kids out there in New York state who won't graduate high school because they can't pass the Math A Regents exam. There's even an art Regents now! I did alright on my earth science, biology, and global studies Regents. The funny thing is that the English Regents doesn't happen until 11th grade. My 9th grade English teacher gave our class the previous year's 11th grade Regents as our final for some reason. I scored a 98, two years before I was due to take it.
I took the SAT twice, in 7th and 8th grades, as part of the Johns Hopkins program. We won't even talk about my scores and how I don't believe that anything can be learned about my intelligence or path in life because I don't know what owl:___ as kitten:rhinocerous.
Standardized/achievement tests are, in my opinion, a useless, unnecessary, time-consuming waste. Instead of spending endless weeks of classtime doing practice tests of this nonsense, why don't we teach our kids how to read and how to function in the real world. And I don't blame the teachers; I understand that they're just doing what their state/district/curriculum requires them to do. I know that many teachers are against standardized testing as well.
