1. A. Custom Woodworking Fundamentals
A1 Materials and Processes · A2 Tools, Equipment, and Techniques · A3 Terminology
- Custom Woodworking: From a Plank to a Finished Cabinet – Custom woodworking is making furniture, cabinets and other wooden items to a design. You choose a material (solid hardwood or softwood, or manufactured boards like plywood and MDF), read a working drawing, plan a cut list, measure and mark accurately, cut (allowing for the saw kerf), shape and join parts with suitable joints, assemble with glue, clamps and fasteners, check quality, and finish the surface by sanding and applying a coating, always following safety rules.
2. B. Design, Layout, and Planning Skills

- The Design Process: From Problem to Product – The design process is a loop of steps designers use to solve a real problem for real people: investigate the need, define it in a brief and a measurable specification, generate many ideas, build a prototype, then test and evaluate it against the specification. Whatever fails sends you back round the loop. This repeating is called iteration, and it is how almost every product, app, building and artwork is improved.

- Basic Computer Organisation – A computer system has hardware (parts you can touch) and software (instructions). Input devices bring data in, the CPU (ALU + Control Unit + registers) processes it, and output devices give results. Memory forms a ladder: registers and cache are tiny and fastest, primary memory (RAM, ROM) holds running programs, and secondary storage (HDD, SSD, pen drive) keeps data permanently. Memory is measured in bits and bytes: 8 bits = 1 byte, and each bigger unit (KB, MB, GB, TB, PB) is 1024 times the one before.
4. D. Technology,the Environment, and Society
D1 Technology and the Environment · D2 Technology and Society
- Environmental Stewardship: Caring for the Planet as We Use Technology – Environmental stewardship means using the Earth's resources carefully so they last, and fixing harm where we can. Every product, from a phone to a hospital machine, has a life cycle: raw materials, making, transport, use and end of life. Each stage uses energy and makes waste. Good stewards keep products longer, choose efficient machines, follow the waste hierarchy (refuse, reduce, reuse, recycle, then dispose), send e-waste to proper recyclers and support laws and company practices that protect nature. Technology can harm the environment, but it can also help: solar panels, LEDs and smart sensors cut waste.
5. E. Professional Practice and Career Opportunities
E1 Health and Safety · E2 Custom Woodworking Business · E3 Career Opportunities
- Health and Safety: Hazards, Risks and Controls – A hazard is anything that can cause harm. Risk is how likely the harm is and how bad it would be: risk = likelihood × severity. A risk assessment finds hazards, decides who could be harmed, rates the risk, adds controls and is reviewed. Use the hierarchy of control: eliminate, substitute, engineering controls, admin (rules, training, signs), then PPE last. Safety signs use colour and shape. Workshops, art rooms and workplaces need guards, ventilation, labelled materials, clear exits and first aid. Laws in most countries make employers and workers share the duty to stay safe.
- Career Planning: From Knowing Yourself to Your First Job – Career planning has five steps. 1) Know yourself: interests, skills and values. 2) Explore career families and find out the work, study needed, pay and demand. 3) Plan a pathway with SMART goals and a plan B. 4) Search for jobs with a CV, cover letter, digital portfolio and interview practice. 5) Make the move from school to work and keep learning, because careers change over a lifetime.
