I'm not close to this woman's level and I haven't done the research, but I have seen the same thing happen time and time again on the high school level. Many students arrived at Packemin with good grades from their middle schools. These students must take a placement test before enrollment and many are placed back in classes they have already passed. In addition, ninth grade teachers also give their classes a placement test and several weeks into the term kids are once again moved around. In the twenty plus years I taught there, I saw kids who could have succeeded fail. I saw kids angered because of their course placement just give up and go with the flow.
I always wondered what would have been so bad if these kids had been given the chance to succeed. Many would have gotten the extra help they needed and rose to the top. I clearly remember Michael, a bright ninth grader whose record, grades and parent showed he should be moved up a year. The placement test showed otherwise and the AP would not permit him to be in the correct class. Michael, a boy who started out wanting to be an engineer, a boy who clearly had the ability, never made it to pre-calculus in high school. I don't know what he is doing now, but when I last saw him, a career in mathematics was not in his plans. Nory, on the other hand, a young lady in the same situation was "smuggled" into a higher level class with the help of her counselor and a fellow math teacher. Nory ended up in AP calculus and is currently a student at Sophie Davis School of Medicine. Luis, another bright and extremely immature young man wanted to see how many letter patterns he could make with the choices on his entrance exam and of course scored poorly. Lucky for him, his talent was spotted early and several teachers inspired him to succeed. He just graduated college with a degree in computer engineering, soemthing his placement test would have prevented.
I'm not saying kids don't need remediation. Many do. But, there is more to the student than just an entrance exam. Maybe they need a chance to jump in. If they fail, so what? There is always a time to repeat. And, if we weren't so hung up on statistics, they would get this chance. I used to think money was the issue. Schools didn't want to spend the money to let kids repeat. Schools waste more money trying to get kids to pass remediation than they would if they just let them take what they need and what their records show they can do.
