• A key administrator: science supervisor, district curriculum coordinator, building principal, assistant principal, or science department chairperson with budget authority
• A team coach: teacher or supporter selected from among the team members to facilitate and guide the team as it works together to become more reflective about adult learning and the change process
• At least two science teachers: involved in the implementation of new instructional materials

Optional Team Members may include

• Additional Teachers: especially teachers representing other middle or high schools in the district, or teachers from content areas that will soon be selecting new instructional materials
• A district, or community supporter: recruited to support the team's efforts; can be a school board member, a consultant, retired teacher, pre-service teacher educator, or member of the business community.
