There are important changes to medical interpreter testing. To increase our certification capacity, DSHS LTC has expanded test options for medical interpreter candidates.  

Starting January 1, 2023, all medical interpreter candidates who wish to pursue a DSHS medical interpreter credential and medical interpreters with expired credentials need to test with one of the third-party testing entities. (Please visit the Test Information page for detailed information on third-party medical interpreter testing.)

There are no changes to the Social Service interpreter tests and Document Translator tests (open to all candidates).
