This article provides a 10-year review by the test developers of the Canadian English Language Benchmark Assessment for Nurses (CELBAN™). From 2004 to 2014, the development, implementation, national administration, and operations of CELBAN and CELBAN-related products and services were the responsibility of the test developers and team at the Canadian English Language Assessment Services (CELAS) Centre at Red River College, Winnipeg, Manitoba. The CELAS Centre team experienced both challenges and opportunities during this 10-year period. As CELBAN expands, and in light of its current profile as a high stakes language assessment tool, a time for reflection and review is warranted. This retrospective review of CELBAN provides an overview of its history, administration, operations, and growth, as well as challenges experienced and lessons learned by the CELAS Centre team. Further research and development ideas are also posited by the CELBAN test developers.
