Language Testing and Certification Program

Latest News


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

New 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.)

DSHS medical interpreter tests are only open to candidates who took medical interpreter tests between 1/1/2018 and 7/31/2022 and are yet to be certified. These candidates have two chances in total to pass each test (written and oral) by 12/31/2022. 

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