ECE Practice exam...meanings

[mjno]

Hey Jeff,
Thanks again for the reply.

I also did a little research and found in the 2007 ECE Ethics content guide (after finally reading it) that the test actually consists of 160 questions and you have 3 hours to complete it. They graded both the exam and practice tests in what is called instant response theory (IRT) method (Snazzlefrag posted something on this a while ago). It is not like the Clep/DSSt scoring apparently they grade it on the difficulty of the questions to really asses what you know (If you really want to be bored just google IRT scoring unless you like statistics). The IRT method grants a higher score to harder questions then to an easier ones; that is why sometimes people that have taken these exams thought they did better/worse than they actually did on the tests. Lets say for example you have 20 questions and answered 15 easy questions right and 5 hard questions wrong then it may be equivalent to 2/3 of 20 correct (according to IRT scoring) instead of 3/4 of 20 correct because more weight is given to the difficult questions (I know I am starting to babble on). From what I understand the difficulty level of the questions is based on a curve (based on how many got what right or wrong) but the test itself as a whole is not.
I do appreciate your replies and based on the fact that you also have this test coming up I want to return the helping hand. I do not know when you are taking ECE Ethics but another thing to think about is that on October 1, 2007 they will be changing things up again.

Thanks again,
Mike
