Staff members are specially trained and work within a collaborative model of service. Teaching staff participate in on-going professional development to ensure they keep abreast of current research and educational practice. Education Assistants work alongside the Teachers in the classrooms or support the speech and language program by carrying out specific individual speech and language activities under the direction of the Teacher or the Speech Pathologist.

Peel Language Development School also has the services of school based Speech Pathologists who play an integral role in planning and implementing the specialised program with the help of Language Support Teachers, including coordination of assessment and monitoring systems.
