TA: Pros and Cons

I've been having a lot of trouble with coming up with a subject. My biggest problem is that I come up with subjects that don't seem to have two sides. Originally I wanted to do standardized testing with an emphasis in exit examinations. However, I think I found a new subject. But I thought doing a pros/cons on my original subject would make a good practice, since that's what we're doing in class, sort of.
Pros for standardized exit testing:
1)You could cut down standardized test to a single exit exam in junior high and one in high school.
2) It would theoretically guarantee a minimum standard between all schools in America.
3) It would make a high school diploma much less subjective for each school.
4) You could use these tests to help sort students into magnet schools or into classes that they need.
5) It would be a good standardized test to base a school's academic achievement off of.

Cons for a standardized exit test:
1) Standardized tests can show racial/social discrimination which could adversely affect students.
2) This still leaves the problem of teaching how to take tests instead of studying actual material. It’s the problem of teaching kids what to think instead of how to think.
3) It’s not the exit test that’s important, but the entrance test into college, because no one can do much with a high school diploma anyways, even if it did guarantee certain skills.
4) It would keep back students who didn’t want to go to school, which would create a great deal of dead-weight in the senior classes of high schools.
5) It’s possible a national standardized test would create even more useless bureaucracy in the government that would hinder instead of hurt people.

6) If it doesn't directly work for the student's interest, then it probably isn't a good policy, and it's hard to make this work for a majority of student's best interest.
