The Department's latest weekly update on the ARRA (released on 10/21) included the following:
The Department submitted to OMB and internal clearance the notice of final priorities, requirements, definitions, and selection criteria; the notice inviting applications; and the application for the $4.35 billion Race to the Top competitive grant program.
The internal document clearance process can take a while (a bunch of offices must approve), and getting OMB and White House sign-off can take even longer (again, lots of cooks in the kitchen), but this suggests that these important RTT docs aren't far from being finalized and released.
