Audiology & Speech-Language Pathology Interstate Compact
The ASLP Interstate Compact has been enacted in many states, but only a small number are currently issuing/accepting compact privileges via CompactConnect. Most member states are still pending operational implementation — verify per-state status before relying on compact privilege.
Washington has enacted the ASLP Compact but is not yet operationally issuing or accepting compact privileges. Until Washington completes implementation, you must apply for a Washington SLP license by endorsement — even if you hold an active compact license in another state. Verify current status with the Washington Board of Speech-Language Pathology before assuming compact privilege is available.
