I taught 2nd grade for the Chicago Public Schools and I was just accepted to graduate school. Although I haven't started as an SLP (not even close!), I observed a lot of SLPs in the public schools. From what I saw, there is less "paperwork." Although you do IEPs as a classroom teacher, you obviously have to do A LOT more IEPs, but at least in Illinois they only need to be reviewed every three years, earlier if they're being dismissed from services. Lesson plans are far less extensive from what I could tell and I'm not sure they even have to be submitted and no grading of course, but you do need to complete assessments and create your schedule, which seemed complicated to me! Best of all, NO pressure from testing, which is a big reason I left teaching. Finally, you're paid more and from what I saw there is less work outside of the "classroom." I plan to fill this time with private clients once I get my Cs.
