which design and methodology show i use on my research paper "What
impact does certification have on student achievement?".  I am willing
to pay more if you can help me with this project.

My personal opinion is that teacher certification has very little to
do with student achievement. Yes, teachers need to have expertise in
the subjects taught but I think it's much more important to have a
love for teaching -- and for the students. Teaching is as much an art
as a skill and teachers who can ignite the desire to learn and inspire
the student are more precious than all the certified experts who can
jump through all the administrative hoops.

I appreciate your comment although it doesn't help much.  Will you be
able to answer my question? Are you a researcher?
