The bill amends RCW 43.43.837 to strengthen the requirements for fingerprint-based background checks for individuals applying for positions that involve working with vulnerable populations, such as children and individuals with developmental disabilities. It mandates that applicants for roles like long-term care workers and direct care workers must submit fingerprints for a national background check conducted by the Washington State Patrol and the Federal Bureau of Investigation. The bill also clarifies key definitions related to applicants and service providers, ensuring that those with potential unsupervised access to vulnerable individuals undergo thorough vetting.

Furthermore, the legislation specifies the conditions under which fingerprint checks are necessary, particularly for individuals who have lived in the state for less than three consecutive years. It introduces a provisional hiring period of 120 days for applicants awaiting background check results, provided they are not disqualified based on initial findings. The bill also ensures that the costs of these background checks are covered by the relevant departments, removing financial barriers to hiring essential service providers. Additionally, it defines "transitional care facilities" and clarifies the meaning of "unsupervised" in the context of working with vulnerable populations, thereby enhancing safety and oversight in care settings.
