The central argument of this essay is that Montessori teacher training offers a unique perspective on professional preparation, which is grounded in the core values—and paradoxes—of Montessori education. The author highlights three concepts—culture, craft, and coherence—that are common to the lexicon of teacher education but experienced distinctively in Montessori education. The essay probes several conceptual puzzles aimed toward reconsidering key ideas related to the development of cultural and technical expertise.
