The Full OPI Workshop is an intensive four-day introduction to the techniques of administering and rating the Oral Proficiency Interview. The rating scale and techniques for eliciting a ratable sample are highlighted in daily plenary sessions and then reinforced in language-specific break-out sessions. Participants have the opportunity to observe live demonstration interviews conducted by their trainer. Under the trainer’s supervision, they then conduct their own practice interviews with volunteer candidates. The group critiques and discusses both these practice interviews and their ratings. Following the workshop, participants may apply to become ACTFL OPI Testers.
