For all questions relating to scope of practice, the NSRP always recommends to registrants that they refer to the NSRP definitions of practice areas. The URL is below:

Rather than issuing a blanket commentary on whether “CBT intervention for children and adolescents is considered a competency for MASP candidate registrants”, NSRP would recommend that registrants with the practice area of school psychology refer to its definition. Specifically, we recommend that you consider whether your use of CBT would relate to the following:School Psychology is the application of knowledge about human behaviour and development to the understanding of the social, emotional and learning needs of children, adolescents and adults, and to the creation of learning environments that facilitate learning and mental health.
You may find it helpful to review this with your NSRP Supervisor.
