I agree, but assume standardized testing takes a full 2 days / year and you either do it every 4 years (3th, 9th, 11th) or every year. Well every year costs an extra 2 days on 3 / 4 years and assuming 180 school days a year that's (2*3/4)/180 = 0.83%.
So, yea it's probably not that useful, but if you want to get upset over something focus on the terrible quality of textbooks or something that can have a slightly larger impact. Even the school lunch program has a larger impact on student performance.
PS: Or just mandate that standardized testing does not count as part of the minimum required instruction time per year.
I did carefully leave "standardized" out of my comment. I have a problem with the whole process of present->practice->see what stuck. It has been the most practical method for teaching large groups of people for a long time, but I think there is a lot of potential in using adaptive testing to mechanize the evaluation and tracking of what students understand, which hopefully leads to students getting more and better personal attention.
