About the Program
Day 1 will focus on an introduction to the science behind the stress-grading rules and how the rules impact the performance of timber; it will also examine issues associated with existing structures and with reclaimed or reused timber.

Day 2 will examine the WWPA stress-grading rules as they pertain to structural timber, and apply those rules to full-size samples via hands-on exercises. Since grading rules are similar across agencies, skills learned will apply beyond the species graded under WWPA rules.

Day 3 will continue with hands-on training, and will culminate with a written and practical examination.

Upon successful completion of the course, participants will be able to:

Understand the effects that defects in a timber have on its strength characteristics.
Understand the science behind the rules for visual grading.
Correctly apply industry-standard grading rules to stress-grade a timber.
Make informed decisions on assigning grade to timbers in existing buildings.
