Become a Certified Authorized Provider to Conduct a DID

LIDDAs can request that the Texas Health and Human Services Commission certify an employee other than a licensed psychologist to conduct a determination of intellectual disability (DID). This can be especially helpful to LIDDAs that are facing an increase in the number of DIDs to be completed with the launch of Community First Choice.
