I used that phrase in a paper I wrote for class this week, about parent/educator (therapist) collaboration. I really appreciate the definition and application. To quote from my conclusion :

As indicated in the research, it is necessary for lines of communication to remain open. This allows information about special education, IEP meetings and goals, and other important knowledge that would support the student, to be available and shared between parents and educators. When this collaborative relationship is successful, the synergistic effect will enable optimal success from the beginning of services through transition to the student’s chosen post-secondary role in life.
