The Terms of Reference for this study are at http://www.icann.org/en/committees/dns-root/root-scaling-study-tor-05may09-e.... Interisle was selected to perform this study.

The steering group will be evaluating the report against the Terms of Reference and preparing recommendations for the Board and the public. Kind regards, Bart
