We will select 14 interpreters for both the Graduation to Certification program and the GTC comparison group. Interpreters in the GTC comparison group will complete the same pre- and post-evaluation measures as the GTC program group. Those in the GTC comparison group will have their RID performance test paid for by the grant, similar to those in the GTC program group. Being able to compare the results of the two groups will enable us to draw conclusions about the GTC program with greater confidence. Both groups play an important role in understanding more about supporting early-career interpreters as they pursue RID certification.
