     At Anacostia Senior High School we have a lot of problems. We have students suspended and we have

low test grades. I think this school is in need of improvement. The reasons why I believe this school needs

improvement are that children are getting suspended and missing out on class work, students are failing,

and the school is dirty.

     The first reason why this school needs improvement is that children are getting suspended and missing

out on class work. Students should not get suspended because it's like a vacation to them. They will not

change their ways. Instead of putting them out of school for suspension, we should have them in school.

In that way, students can still have good grades.

     The second reason why I believe this school needs improvement is that students are failing. If you come

to school every day you shouldn't fail. I can't blame it all on the students; it is the teachers' fault also. Some

teachers do not let students in the class. This school needs tutors. If students had tutors their grades could

improve. 

     The third reason why I believe this school is in need of improvement is that it is dirty. Who wants to walk

into a dirty school every day? I don't! If students help out, the building will stay clean. There should be no

writing on the walls or eating in the halls. We need to treat our schools like we treat our homes.

     These are my reasons why this school needs improvement. If we do these things we can get good grades

have a nice looking school, and students will improve their grades. By doing these things we can also have

the most decent school on the other side of the fiver.
