CCHI is in the process of convening an Advisory Panel that will develop an evaluation process for LP tests and help create a national Registry of Accredited Language Proficiency Tests. Until this Registry is established, CCHI Commissioners approve LP testing vendors at their discretion, applying CCHI’s evaluation criteria.

If you are a testing vendor and wish CCHI evaluate your LP tests for inclusion on this list, please contact us at solutions@cchicertification.org and include “language proficiency testing” as part of your subject.
