Should teachers be fired for poor academic performance by their students?

how much responsibility do you think teachers should take for the academic performance/test performance of their students? do you think teachers should lose their jobs?

In the past few years, in towns and cities across the country, teachers were fired or attempts were made to fire them because of poor performance by their students. The teachers argue, and the arguments are probably at least somewhat justified, that they are battling budget constraints that make teaching tools, books, etc. unavailable, problems in the homes, absenteeism, all kinds of problems where school may be low on the list of priorities for the child, yet the teachers get the brunt of the blame.

I saw a documentary on it (HBO? i don’t have a link), portraying the Baltimore MD school system, showing the administrators going to the kids’ homes to discuss their absenteeism, showing kids cutting class, hanging out in hallways, loitering, showing how the majority of kids that enter 9th grade will drop out, and showing the school administration conducting meetings with the teachers telling them they will be fired if the grades don’t get better. They showed the teachers saying they are up against many obstacles, most are out of their control. They showed Parents’ Night, where each teacher may have 1 or 2 parents show up the entire night. They showed the young, inspired teachers leaving for better school districts. You could see where the apathy, the frustration, the pessimism comes from on the part of the teachers and administration. It seemed like they cared but they were up against so much.

what do you think? should teachers be held responsible and possibly lose their jobs over poor academic performance and low test scores?
