Working at City Schools can be hell but, depending on the school, ECE is probably the best teaching position to be in if you have the energy to run around with kids all day. No state testing, no grading, no wit and wisdom BS. Best thing you can do is learn Spanish, there is a large demand for that in the schools in South and East Baltimore, especially in ECE where the kids have not been in an English language environment before.

For alternative certs, apply for TFA (if you put Baltimore as the only city in your top choice list, 90% chance you’ll get it), apply for Urban Teachers, and apply for BCTR. If you get TFA, go for that just for that for the resume builder. If you don’t get it (it’s competitive), then decide between Urban Teachers and BCTR. BCTR is less of a time commitment, Urban Teachers will leave you more prepared/ give you a year of student teaching to go “oh, nevermind, fuck this” before you commit to your own classroom.

Like everyone said, do not accept any offer until you speak with teachers at that school (and, ideally, not ones that the principal directed you to). Half the principals in this town are sadists.
