NOFMA grading and milling standards have been established to ensure expectations are met regarding how wood flooring appears, ease of installation, sand and finish, and ultimately how it performs. Today those standards continue to be the industry measurement for wood flooring manufacturers.

NOFMA Grading Rules and manufacturing standards are proprietary to the members of NOFMA. The information in this section is intended to provide a general overview of the standards and why they are important. The only way to be sure the flooring you buy lives up to these standards is to specify NOFMA-certified flooring for your project.
