Washington State Dept of Early Learning has a website which permits anyone to view basic information about licensed child care facilities, including information about licensing complaints that are found to be valid (proven); it does not report CPS information. If you do not find the provider that you are looking for, the business could be unlicensed. Its a good source to use when looking at child care. Find it here:
