Run-out-of-time (R.O.O.T.) Rule

If a candidate runs out of time before reaching the maximum number of items and the computer has not determined with 95% certainty whether the candidate has passed or failed, an alternate criteria is used.

• If the candidate has not answered the minimum number of required items, the candidate automatically fails.
• If at least the minimum number of required items were answered, the computer looks at the last 60 ability estimates:
  • If the last 60 ability estimates were consistently above the passing standard, the candidate passes.
  • If the candidate's ability estimate drops below the passing standard even once over the last 60 items, the candidate fails.
