Wisconsin Local Use Dimension Lumber Grading
Instructors: DNR Forest Products Team
The purpose of the Wisconsin Local Use Dimension Lumber (WLUDL) grading certification is to allow the use of locally milled dimension lumber in one- and two-family residential construction. By completing the training program 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 you will:
- Gain an understanding of basic wood science and material defects
- Obtain hands-on experience grading lumber
- Gain the skills and certification needed to mill and sell for the construction of one- and two-family dwellings
This program is open to any individual interested in obtaining the WI LUDLG certification.
