A learning liaison is a campus-based instructional coach. These educators are former classroom teachers who have specialized training and expertise in curriculum/instruction design and development. Their primary responsibility is to build instructional capacities within GCISD's teaching staff. Their services include coaching individual teachers, modeling instructional strategies, providing professional learning to teams and groups, facilitating Professional Learning Communities, supporting assessment development and data analysis, interacting as a member of the campus leadership team, and serving as a conduit to campuses for Curriculum and Instruction Department support. (See also Instructional Coach. In GCISD, instructional coaches serve in either a campus-based role, referred to as a Learning Liaison, or in a centrally-based role, referred to as an Instructional Coach, within a department on the Curriculum and Instruction team.)
