Standardized Testing: Why Do We Need It?

I personally dislike writing tests like this because they stress me out and I'm probably not the only one who gets stressed over them either. I think they are good to see where the students are at in English and Math but they shouldn't count for marks. I know OCA is just a test to see where you are in English because you're coming from middle school and it is a good test so you know what will be expected of you in grade 9 English class. Grade 9 EQAO is used for marks in Math class which I don't think is fair because some people get stressed on tests and actually do worse than they know they can. I know it doesn't affect marks by a lot but it could put someone into the position of failing right before exams. In grade 10 all students are forced to take the literacy test. If you don't get above a certain grade you can't graduate until you do or take a course to get the credit to graduate. This is not fair because a student who gets 90% in English class could fail somehow because of something stupid and have to take it again in grade 11. Overall I think these standardized tests are dumb and unnecessary. They should be used to see how the student is going not for marks.
