Definition: A window is a time frame, an opportunity, during which an activity may occur.

What This Means: Windows are contrasted with deadlines or target dates as allowing a range of dates for performing a task. A window is defined with a start and an end date rather than merely a single due date. For example, instead of a statewide assessment being administered on May 1 everywhere, there may be a window from April 15 to May 15 allowed for administration.
