How Is Our School Organized?

Our school is organized into interdisciplinary teams of teachers who are responsible for the academic, social, and emotional needs of their students. In addition, there are three other teams: a physical education team, an arts team, and a special needs team. Our team structure is designed to provide a strong sense of belonging between students and staff. Students are assigned to teams to ensure a balance between races, gender, ability, and former elementary school attendance.

We cluster our special needs students at each grade level. This allows us to maximize our support for them since we use a plug-in-model for our delivery of services. ESOL students are also clustered for the same reason. Each grade level comprises as one Super Team. As a result, teachers are able to share common concerns on a daily basis in team meetings, conduct parent conferences with all of a child's teachers in attendance, improve the efficient planning of team activities, and coordinate the instructional program for all subjects.

Support staff, specialists, counselors, and administrators are also assigned to each team. These staff members bring additional resources to support the instructional and administrative needs of the team.

Our practice of having the same guidance counselor stay with the same group of children for their three years at Cabin John Middle School has proven to be a real asset in terms of continuity and communication among staff and with parents.

How Important Is Professional Growth?

Great emphasis has been placed on teacher training at Cabin John and its significance to instruction in the classroom. Many of our staff are enrolled in classes, attend/and or present at conferences, and are members of curriculum development teams. Our active in-school in- service program looks at the needs of students through analysis of data and surveys. The objectives of our management plan are developed in partnership with the community and focuses on specific needs identified by both staff and community, using MCPS goals as our benchmark.
