Max Riser Height - Codes and Regulation
I'm a little bewildered at this one, the answer goes against any common knowledge I've experienced and just seems flat out wrong. Hoping someone from NCARB sees this and if I'm wrong please explain how.
The NCARB post-exam feedback associated with a question in the Codes & Regulations section of PPD Practice Exam explains that 6 inches is the "Max Riser Height".
What code/regulation is this stemming from? 2018 IBC Section 1011.5.2 stipulates a 7" maximum riser height.
I'm happy to provide more information but I am weary to take screenshots of even the practice exam. The question is related to the given height of a ramp and the number of risers that would be required to hit the same height.
Thank you :)

Hello Samuel,
Taking screenshots of the practice exam and posting them here is perfectly fine since that is a publicly available resource to candidates. I believe however that I found the item you were referring to. At the end of the scenario in the question it says that "each riser must be no more than 6" high". It is not saying this a code requirement but a parameter for this specific case. While 7" is the maximum allowed by the model code, 4" is the minimum so this 6" requirement would be permissible.
When taking the exam, make sure to use the information directly stated in a question to answer it. That information may not be exactly to the building code but it would also not ever be in direct violation of it either.
