How is the reliability of the exam being ensured?
PTC is responsible for the reliability of the exam. All questions are subjected to the item review and exam review process, where they are reviewed, evaluated and referenced based on appropriateness, currentness, clarity and correctness. All items are also subjected to item analysis after the test has been administered and before candidates receive their scores. This process begins before each examination reaches its final form and is currently underway for the December exam.
