Inside One State's Bold Plan to Keep Special Education Teachers Pennsylvania's training and mentoring program works to retain teachers serving students with disabilities.

@sparccenter.bsky.social research shows why #SpecialEd teachers leave: lack of support. PA’s Attract‑Prepare‑Retain initiative is fixing that with targeted mentoring and training (and early results from @caldercenter.bsky.social).

Thanks to CALDER's @zeyuxu.bsky.social, @cedr.bsky.social, and Rachel Dao for their work on this paper!
