Schools should drop underachieving students

"This was not stated previously by my opponent, and it was presented by his argument that it is justified to drop the student for the sole reason for getting 70% or lower. It appears as if my opponent agrees that if the teacher is not doing her job correctly, the student does not deserve to be dropped. Thus, proving my opponent wrong." -> A school test is a test that is in accordance to the standard of that schools educational system. Therefore, a test that does not adhere to those guidelines is invalid as it is not testing what was intended. Therefore, the student could not be consider an underachiever by this school system which gives it no reason to drop the student. Misrepresenting the Pro's arguments: "Regarding my opponent's argument, my opponent's logic is that if the child gets below 70%, it is best for everyone if we drop the child." -> I stated that dropping the student was the best course of action for the other students. Nowhere do I mention everyone since that would be a clear generalization. "1. The U.S., which had some of the highest graduation rates of any developed country, now ranks 22nd out of 27 developed countries. 2. A high school dropout will earn $200,000 less than a high school graduate over his lifetime. And almost a million dollars less than a college graduate" -> This arguments are from the perspective of the dropouts which I have not debated. I will merely counter that these statistics don't account for the future difficulties and lower salary that the others students (they will be under qualified) will encounter because of the slower learning pace in a school system that keeps its underachievers. Generalization: "3. In the U.S., high school dropouts commit about 75% of crimes" -> This study is about the current high school dropouts which involve many students who voluntarily dropout of high school. Therefore, this study cannot be accurately implied to the hypothetical students that would be forced out of the educational system. -> In addition, correlation does not imply causation. There could be a third variable such as the type of neighborhood in which the child grows up since poorer neighborhood are correlated with abusive family homes. Bias: "Now, with forced dropouts, it is greatly expected to see a decline in jobs (thus theoretically causing a decline in the entire GDP), and increased criminal activities." There is no guarantee that the GDP will go down. GDP is based on productivity not on how many workers are present in the workforce. In addition, those who dropout of school would simply take a minimum wage jobs therefore they are not outside of the workforce. Theoretically, the GDP might even increase since the remain students (the majority of the student at the school) would be more prepared for the workforce and thus more efficient. "It is very possible that the child can progress later on. The emotions of the child can change, and he/she becomes an achiever in his/her later years." -> It is possible but unlikely since humans are creatures of habit and have strong tendency to conserve their energy (to do the minimum, especially if they lack interest). In addition for a person to alter their personality requires a lot of time and effort. "Students should only drop out, when they feel it is best for them." Why should the interest of a few students trump the ones of the many? The school system should factor the interest of all of its students in its decision not just those with difficulties.
