Westhampton Elementary School, (Westhampton, MA). Westhampton Elementary approaches professional development (PD) as a four-tiered system rooted in the academic, social, and emotional needs of the students and school community. This tiered system begins at the district level where school administrators work closely with the district’s curriculum director to program professional development activities that benefit the work of all professionals across the schools. The second tier is building-based. Throughout the school year, the school’s staff engage with PD designed through collaboration between the principal and the teaching staff that is strategically aligned with the school’s needs. The third tier occurs at the classroom level and focuses on classroom instruction and assessment. The principal encourages teaching staff to observe and be observed by peers and work collaboratively. The final tier of PD is determined by individual teachers. Every teacher is required to create both a professional practice goal and a student learning goal at the beginning of the school year. To address these goals, individual teachers attend professional workshops, complete graduate courses, and develop curriculum as needed.
