Wisconsin Local Use Dimension Lumber Grading
Wisconsin Local Use Dimension Lumber Grading Certificate
The purpose of the Wisconsin Local Use Dimension Lumber grading certificate is to allow the use of locally milled dimension lumber in one- and two-family residential construction. By completing the in-person training and passing the associated exam, participants are given the proper training and certification to mill and sell lumber under the local use dimension lumber grading system. Certification is valid for five years, after which recertification is required by completing another course. As part of this course, participants will gain an understanding of basic wood science and material defects, obtain hands-on experience grading lumber, and gain the skills and certification needed to mill and sell for the construction of one- and two-family dwellings.

Certification courses are $30 and pre-registration is required. Additional course dates are posted as soon as they are announced.
