Excerpt from the article:

Some court interpreters in California who specialize in Mandarin, Russian and Armenian say they are getting squeezed out of long-held jobs because of a certification process they believe is flawed.

Many say they have taken the state-mandated written and oral tests several times but were unable to pass despite having demonstrated fluency and skill. The issue has created professional problems for some, and it could have broader implications as the courts’ ability to find qualified interpreters becomes further strained.
