IBIS Window Age Calculator

The Window Age Calculator - Millenium Edition (WAC-ME) is a tool that might prove to be useful for recruitment scheduling. Simply click on the text box and use the pop-up calender to create all of the Window dates. Since, there still seems to be some confusion and debate about these dates, I felt that this could also be used as a list for the various problems (see below under Notes and Comments).

Enter birthdate (click on text field):

Notes and Comments:

- The defined window ranges seem too restictive at the sub-6 month border and too liberal at the 9 month end. We are already violating the limits with out first recruit, due in on December 6th. This candidate will be 4 days too young. I think we should redefine the actual window ages.

- Note: The screening instruments do not all cater to these rules. For example, the screening instruments like the Telephone Screening Interview (TSI) can be administered far outside these dates.
