MANHATTAN, N.Y. - iSportsWire -- What does it actually take to lead a school where every student succeeds? Not buzzwords. Not another professional development binder. According to veteran educators Michael Sonbert and M. Antonio Vance, it takes a willingness to ruffle feathers, say the hard things, and hold every adult in the building accountable. Their new book, Unshakable Leadership: 21 Strategies for Success in Urban Schools and Beyond, published by ISTE+ASCD and set to be released June 25, 2026, is the no-nonsense playbook K–12 leaders have been waiting for.

Forged in the fires of challenging urban school environments, the book cuts through education's chronic love affair with jargon to deliver something refreshingly practical: strategies you can implement on Monday morning. Sonbert and Vance organize their 21 strategies around the pillars that make or break schools — crucial operational processes, the leadership team dynamic, instructional quality and coaching, and the all-important school culture. For each strategy, they lay out why it matters, how to roll it out, what pitfalls to avoid, and how to make it stick.
