Our mission at the Knee Regulatory Research Center is to provide a resource for professionals,
policymakers, and researchers about the scale, scope, and specific requirements
of occupational licenses in all 50 states and the District of Columbia. As a part
of that mission, we maintain a database of licensing requirements freely available
on our website. The database grew out of a Department of Labor grant-funded project
for the Commonwealth of Pennsylvania. Over time, it grew to be a resource to track
the requirements for any profession licensed in the US. We update the database
on a regular basis to ensure the data reflects the current regulatory landscape.
