TL;DR:
This study compares 11 variations on 5 qualitatively different approaches from recent literature for selecting optimal anchor items and indicates that for nearly all conditions, an easily implemented 2-stage procedure recently put forth by Lopez Rivas, Stark, and Chernyshenko (2009) provided optimal power while maintaining nominal Type I error.
