Woodwork Career Alliance Skill Standards
Industry-Approved Standards for the Woodworking Profession. This introduction to the Woodwork Manufacturing Skill Standards serves as the starting point for the development of industry-accepted operational procedures by which to measure performance and results produced by woodworking professionals. This unified North American Standard of Tool Skills & Evaluations has been being written by volunteers from all has been parts of the advanced wood processing industry, resulting in practical, useful skill sets for productive woodworkers. Skill Standards are being developed by The Woodwork Career Alliance as a means to support the woodworking industry in preparing productive woodworkers. It includes a voluntary assessment program that allows woodworkers to demonstrate their competency in in-plant woodworking skills and earn credentials that are recognized throughout North America. Skill Standards provide many advantages to maintain the reputation of today’s woodwork manufacturing industry and sustain industry professionalism in the future. Among these are: 4Professional recognition for our skills. 4Identification of the skills required by industry employers. 4Provision of benchmarks for performance. 4Helping trainers respond to industry requirements. 4Establishing a foundation for credentials. 4Validation of accredited training programs.
Who Benefits from Woodworking Skill Standards? Industry professionals by seeing increased interest in seeking a career path in the prestigious, modern woodworking industry. Company owners and managers by getting help in recruiting, training, and retaining skilled employees. Teachers of woodworking by access to guidelines for class planning and industry outcomes. Students thinking about their future by discovering a career and learning what they need to know to succeed. Shop managers through the ability to test and score employees on their woodworking skills. The Standards are tool operations which can be seen and measured. The level of skill required increases with each tool. A group of skills are assembled into a job description at the shop, and credentials can be issued to recognize accomplishment. Woodworkers by showing knowledge and skill through performance of each standard operation. As the woodworker learns and masters the techniques at the basic level, a clear path for increased skill is set out in the Standards. Experienced woodworkers will pass dozens of the tests to demonstrate their accumulated skills against a consistent industry standard. Use Skill Standards to develop training programs and curricula; to develop a credentialing program; to define job requirements; to recruit woodworking professionals; to plan career development paths; and to enhance labor value and mobility.

Three-Phase Project–2007-2013 The Wood Manufacturing Skill Standards, Evaluations and Credentials Project is a three-pronged effort, designed to take place over the period from 2007 to 2013. The first phase created a framework for development of the skills standards, and was completed in 2008. Phase two is focusing on development of skills criteria and evaluation documents, and will be completed in 2009. The third and final phase will launch a credentialing process for individuals who demonstrate that they meet the skill criteria. Work on phase three is anticipated to take place from 2009 to 2013 before full implementation in North America can be achieved. “These standards, evaluations and credentials will provide a lifeline to those struggling new business people and their employees,” states the grant application. The Skill Standards, Evaluations, and Credentials will serve all levels and sectors in the industry while advancing knowledge, skill and professionalism of the workforce needed to sustain and grow the woodwork industry.

Completing The Final Project When the Skills Standards manual is completed, it will include more than 100 machines and tools as well as the woodworkers’ relationship to them through skill standards, evaluation and a recognition or credit process. The Woodwork Career Alliance (WCA) started with the most valuable, foundational 30 machines and tools. These are the 30 that all woodworkers — from the student, to the apprentice and the master — will always have to know to use them. Even as the industry advances to new and improved technologies, including robotics and other possibilities in the future, there will always be a human that needs to understand and know these 30 operations in order to advance the state of the art. That is the crux of this first release of the Pilot Project of 2009: to put these skill standards and evaluation into the hands of business owners, their employees, educators and those who help WCA spread the word about this program. There are more than 70 more machines and tools to be included in the final project and WCA is actively seeking woodworkers, product specialists, educators and others who are willing to assist the WCA and apply for a spot on the skills standards defining and writing teams to complete the operations listed on the following pages.
How It Works There are 15 general classifications for the work included in the manual. Each classification has from 5 to 25 tools and machines within it. At this time — for the Pilot Program Edition, published in the Summer of 2009 — the 15 classifications are:
Layout Sawing Milling Shaping CNC (Computer Numerical Control)
Boring Sanding Clamping & Laminating Turning Joinery/Assembly Grinding & Sharpening Finishing Related Skills: To be developed in 2011 Technical Terms: To be developed in 2011 Appendix
All the writing and editing is done in an on-line collaborative work space called a Wiki. Much like the wellknown Wikipedia, the WCA Wiki is an open forum. Anyone may visit the space to see the work in progress. Interested subject matter specialists may join the space (there is no charge) and make contributions or edit the work of others. The current working sets of tools and machines are listed in a menu along the left edge of every page of the Wiki. At the very bottom of the menu is a gateway to the archive of ALL the work to date. Links in this gateway take the reader to a matrix of tools and machines inside each of the 15 general classifications. As with all things ‘internet’ changes are made from time to time. If you need access and can’t seem to get it, please feel free to contact any of the WCA Board members. Here are the links to the work as of this writing: The Wiki work pages: http://skillstandards.wikispaces.com The Alliance web site: http://woodworkcareer.org The following pages list the tools and machines in each classification for which Standards are currently being written or plan to be written by 2013.

Assessor Preparation Checklist: This checklist is intended to help the assessor prepare for and conduct an assessment for the Woodwork Career Alliance Skills Standards.
Carefully read through the assessment you will be
conducting, and make sure you understand the criteria you will be measuring.
Be sure you have the necessary stock prepared for the
candidate according to any specific directions listed. When ready, greet the candidate and make sure they
Print copies of the Skill Evaluation Record, Pre-opera-
tion checklist, and the specific operation(s) you will be measuring. It will be useful to have a clipboard to write on during the assessment.
are clear on which skill is being assessed. The candidate should have had the opportunity to read
through the assessment prior to their testing and have the opportunity to ask for any clarification.
Prior to the assessment, record any specific criteria to
be measured, such as finished product dimensions on the Skill Evaluation Record. Also record the candidate’s name and relevant information including the Operation and Skill Level being measured. Gather the necessary tools to measure the outcome.
These may include calipers, a tape measure, square, etc. Make sure these are properly calibrated to ensure accurate analysis of the finished product. If the operation requires the installation of tooling,
make sure the tooling to be selected is present. Level 2 typically requires that the candidate select and install the correct type of tooling, so it is advisable to have a variety of tooling types available so you can test their ability to select the correct tooling.
The objective of the assessment is to test their knowl-
edge. They may ask you questions, but be very careful that you are not giving instruction during the assessment. The observation typically passes quite rapidly. Be pre-
pared to observe and check off specific tasks as they occur. Analysis of the final product can wait until the end, and may or may not be done with the candidate present.
