NBCOT Navigator®—Your Source for Continuing Competency and Professional Development

As an OTR or COTA certificant, you have access to a tool suite called the NBCOT Navigator. The NBCOT Navigator is a virtual platform housing a web-based assessment delivery engine and certificant dashboard.  The platform is designed to interface with a series of tools and resources to support certificants’ continued competency.  Through the platform, certificants can identify and access resources related to specific practice areas, receive feedback and track performance on an array of assessment tools, and organize documentation of completed professional development. 

These innovative resources address all areas of occupational therapy, including orthopedics, mental health, school-based, home health, rehab inpatient, rehab outpatient, skilled nursing, education and research, health and wellness, work and industry, pediatrics, and administration management.

Since it is available online 24/7, NBCOT Navigator also offers greater flexibility when and where you participate in certification renewal activities, reducing the need to step away from clients, work, or home.
