Methods: We conducted a mixed-methods evaluation of Montessori Approaches to Person-Centered Care (MAP-VA) at eight VA CLCs. Trainings were conducted as either a live virtual course or a pre-recorded asynchronous class. Two NPT constructs, coherence building and cognitive participation, informed qualitative interview questions, surveys, and analyses focused on staff movement from knowledge to action during initial implementation. Data collection included staff-completed standardized post-training exams (N = 906), post-training evaluations (N = 761), and optional validated surveys on perceptions of Montessori training (N = 307). Champions (peer-leaders) from each CLC completed semi-structured qualitative interviews post-training (N = 22). Findings: The majority of staff (83%-90%) passed all courses. Staff evaluated the training highly (80%+ agreement) on learning relevant new knowledge and confidence applying new skills. On average, staff felt MAP-VA would become a normal part of their work (7.68/10 scale), and reported increased familiarity with Montessori approaches after training (p = .002). Qualitative interview data from staff trained in Montessori supported three themes concordant with the NPT dimensions of coherence building and cognitive participation. (1) Coherence regarding Montessori: staff demonstrated an understanding of the program and mentioned the benefits of Montessori compared to their previous usual routines. Cognitive participation or engagement with Montessori: (2) staff had positive feelings about Montessori principles/applications and demonstrated a willingness to try the Montessori approach, and (3) staff made sense of the new intervention through early rehearsal of Montessori principles/practices and recognized opportunities for using Montessori in future interactions. Conclusions: Montessori virtual training resulted in high levels of coherence and cognitive participation among multidisciplinary staff, evidenced by high knowledge, self-efficacy, and readiness to act. The asynchronous and synchronous trainings were accessible, relevant, and supported diverse learners.
