It is an unfortunate situation about these sample questions Phil submitted to PWNA. After PWNA publicized them, IKECA said the question were on their exam and filed a lawsuit. The question(s) on IKECA exam were purchased from Phil, meaning that IKECA owned the copyrights to those EXACTLY WRITTEN questions.
As with any test it is important to protect the integrity of it by not allowing it to be viewed except by the author(s), test taker, and the graders. Since this was the case it created a difficult situation for PWNA to verify that the questions actually had existed on the IKECA exam. Furthermore, since both groups were interested in protecting the quality of their exam it made it difficult to actually compare the two tests without compromising them. Since this was the case, I cannot factually state whether the question were or were not under copyright protection by IKECA. I was never privy to IKECA test questions.
It became increasingly obvious that this entire process could become very expensive for PWNA. Legal fees can accumulate very rapidly in these situations. As a board we had to look at this from a financial perspective. It was cheaper to settle the lawsuit than it was to fight it to either prove or disprove IKECA's claim.
Anyway the PWNA settled the suit out of court for $10,000 dollars with which IKECA said they were going to make and educational video for the industry. I believe the video was supposed to be given to Fire Inspectors to educate them about kitchen exhaust cleaning. I don't know what came of the project or the money. To date I still have not seen a video produced from IKECA on the subject. By the way this took place about 5 to 7 years ago.
I wish it had never happened but it did and PWNA has learned from it and moved on. I am not proud of it but am proud of the manner in which we dealt with it. Our decisions were based on what was best for the association and our membership. PWNA now carries insurance to protect us in the future. And we are much more apprehensive about how we put these programs together now.
I hope this answer your questions and we can put the issue to rest one more time.
