This document provides an overview of the structure and content of AAPPL Rater Training 2018. It is organized into six parts that will introduce raters to AAPPL and the rating process. Raters are asked to complete some introductory tasks including reviewing forms, a syllabus, introductory video, and demo test to build their knowledge before beginning the self-guided training modules. The training covers applying concepts of language performance and proficiency to AAPPL tasks, orientation to the rating criteria, and practice and certification rounds for rating interpersonal and presentational language samples.
