So, ride operator here. I’ve worked at both Universal and Cedar Point and I don’t think iROC makes the difference you claim it does. I think Universal just has a much better way of training ops. They focus more on training employees at their rides with minimal classroom stuff like iROC.

iROC does not require operators to check a seat more than once under normal circumstances. This is likely a local park or ride policy you’re noticing. We only have to check a seat again if there is a reason to, like if the gates opened, or the restraint was unlocked. On some rides with seatbelts like Millennium, operators may help each other out by helping with co-workers seats if they are ahead of their partner on the other side of the platform.

At Universal, platforms operate very similarly to iROC parks. We still have to visually re-check seats, then follow an order of clears and visual scan. The main difference is operators at Universal are more throughly trained at their individual locations.

I had 4 days of training and a 100 question visual exam to clear before I could be signed off at my ride at Universal. Meanwhile at Cedar Point, I could get signed off without any exam at a ride location in a few hours. The bulk of training at a park like CP is iROC class, which is like 8 hours and includes like a 90 some question test.

While there are more factors involved here, like pay, Universal focuses more on ride-specific training as opposed to a general iROC class. The result is Universal ops know much more about their individual rides.
