I am a working teacher with a Masters from U of P. From my
learning team of 5. 4 out of 5 of us have jobs...good ones
too. The one who doesn't found out after student teaching he
didn't really want to be a teacher. I would say most of my
class did get hired.
That said, most of us teach at charter or private schools.
I'm the only traditional public school teacher, but I work in
a rural area. I think a U of P degree is not impressive but
will get you a job if you are a good interviewer. Since you
are science, you could look into middle school. That would
make you more marketable. Elementary in the metro area in
fairly saturated, but I'm sure there are jobs to be found.
