Framing and Sheathing (NRCA) Framing and Sheathing (NRCA) candidates frequently overlook the interplay between lumber grading standards and load-bearing calculations, leading to missed questions on joist spacing and deflection limits. Many also confuse when plywood sheathing orientation matters versus OSB applications, particularly under wind and moisture conditions. Sheathing fastener spacing—often tested in scenario-based questions—trips up those who memorize generic guidelines rather than grasping why spacing varies by substrate and load type.
