Question:  I remember some time ago hearing that an assessment cannot be opened either before or after the ARD window, only during.  Is this true?  

Answer: The requirement in the RAI User’s Manual limits the ARD selection to no later than by midnight of the end of the ARD window. It does not put a limit on how early you open an assessment.

The point that could be challenged would be how you would know that a particular ARD is the best ARD to select, the further you are from that date when you select it.
