What is a Log Grader and Scaler?
A Log Grader and Scaler is a skilled worker responsible for determining the volume, species, and quality (grade) of harvested logs. They inspect logs in sorting yards, millponds, or log decks to calculate their marketable content and value before they are processed. Their accurate judgment directly impacts the cost of raw materials for sawmills and paper plants.
Typical Education
A High school diploma or equivalent is the typical entry point. While postsecondary education is not mandatory, employers often prefer candidates who have completed technical training or a two-year associate’s degree in forestry technology or a related field. Most specific measurement and grading skills are learned through moderate-term on-the-job training.

Day in the Life of a Log Grader and Scaler
This job is physically demanding and performed entirely outdoors, requiring resilience to all types of weather. Graders and Scalers must be constantly moving around large piles of logs, often working closely with heavy equipment operators.
Typical daily tasks often include:
- Measuring and Calculating: Using specialized measuring devices (like scale sticks) to measure the length and diameter of felled logs to calculate their cubic volume and weight.
- Inspecting for Defects: Jabbing logs and visually inspecting them for defects such as rot, splits, knots, excessive curve, or insect damage to determine the final grade.
- Grading and Marking: Applying paint marks or stamps of specified colors to the logs to indicate their species, quality grade, and intended mill site.
- Record Keeping: Recording data about the individual logs or entire truckloads into tally books or specialized handheld collection terminals (computers).
- Load Verification: Weighing log trucks before and after unloading, and verifying load specifications against supplier documents.
- Directing Movement: Identifying logs of a substandard or special grade and arranging for their hauling or transfer to the correct processing facility.
How to Become a Log Grader and Scaler
- Gain Foundational Knowledge: Obtain a high school diploma. Courses in math, forestry, and wood technology are beneficial.
- Seek Entry-Level Work: Begin working in a labor role in a sawmill, lumber yard, or logging operation to become familiar with log species and common defects.
- Complete Training: Receive on-the-job training under a senior scaler. This training focuses on mastering the specific grading rules and local standards used to assess wood value.
- Certification: In many states, log scaling and grading must be performed by an individual who is licensed or certified by a state agency or a cooperative grading bureau.
Essential Skills
- Attention to Detail: Meticulousness in spotting small defects and accurately measuring logs, as small errors translate to significant value loss.
- Physical Stamina and Agility: The ability to walk, climb, and maneuver safely over uneven piles of logs in all weather conditions.
- Integrity and Objectivity: The highest degree of honesty is required, as the scaler's judgment directly impacts the payment made to log suppliers.
- Mathematical Proficiency: Strong skills in arithmetic and using conversion tables to quickly calculate volume, board feet, and weight.
- Species Identification: Expert knowledge of local tree species by their bark, wood characteristics, and common defects.
Key Responsibilities
- Accurate Valuation: Providing precise volume and quality estimates for every log entering the mill.
- Quality Control: Ensuring that only materials that meet the mill's specific standards are accepted for processing.
- Inventory Management: Maintaining accurate, defensible records of all incoming log volumes and grades.
- Safety Protocol: Adhering to safety standards while working around moving logs and heavy loading equipment.
