Is anyone out there aware of research that has sought to establish the relationship between Spanish learners' scores on the ACTFL Proficiency Placement Test (APPT) and their scores on the ACTFL Oral Proficiency Interview (OPI)?
I realize that the APPT is not meant to determine official proficiency levels at all, but I'm curious as to how well the APPT, as an instrument of reading and listening interpretive proficiency, can predict oral interpersonal proficiency. If there is research on these exact instruments, or on how well interpretive proficiency can serve as a predictor for interpersonal proficiency in general, that would be great.
