An assessment system and method are provided for determining whether an item handled in a material handling system is stable and conveyable or unstable and non-conveyable. If an item is deemed non-conveyable, it is diverted or otherwise removed from the material handling system before it is transported downstream where it may affect the operation of the system or cause damage to the system and/or item. The system utilizes a dimension sensor system, such as including photo arrays, to measure contact region dimensions between an item being conveyed and the conveyor surface. The contact region is observed under constant conveyance rates, accelerating conveyance rates, and decelerating conveyance rates to determine whether the item orientation changes due to shifts in momentum. Any measured contact region changes are compared to a maximum allowed value, and if the measured change is greater than the maximum, the item is deemed non-conveyable.
