Public reading is free. Some external platforms offer optional paid services, accounts or exams; those are not needed to use this guide. Check each material’s edition, license and course relevance. Practical or regulated work still needs the appropriate instruction and authorization.
All trades
Build confidence with fractions, decimals, ratios, percentages and introductory equations. Read online before buying a textbook.
A useful first task: Try one worked example, then solve a similar exercise without looking at the answer.
Construction
Explore hazard awareness and the language of construction safety. Reading these pages does not issue an Outreach card or replace supervised instruction.
A useful first task: Make a list of terms to discuss with your instructor, including fall protection and equipment-specific training.
HVAC
Understand the certification route and follow the official test-topic links. These are reference materials, not authorization to handle equipment.
A useful first task: Identify the equipment category you intend to study and the approved testing organization.
Manufacturing
Explore the openly readable Welding Metallurgy course outline and learning materials. Check each item’s date and license before reuse.

Transportation
The FAA offers free maintenance handbooks covering general, airframe and powerplant material. Downloads can be large.

A useful first task: Explain the energy conversion in your own words and identify which equipment needs further formal study.
Energy
Explore wind-turbine components and how wind energy becomes electricity.
A useful first task: Label a simple system diagram before comparing mechanical, electrical and technician courses.
Healthcare
Read foundational anatomy and physiology openly. This is study support, not clinical instruction or a medical credential.
A useful first task: Practice anatomical terminology and basic body-system relationships; follow your course’s required edition.
Beauty and wellness
Explore workplace health and safety topics relevant to nail-salon work. Local practice and licensing rules remain separate.
A useful first task: List questions about ventilation, product information and ergonomic arrangements for a school visit.

Use the public model-code resource to understand food-safety terminology. The Food Code is a model; local adoption and requirements vary.
A useful first task: Learn the distinction between a model rule, local requirement and your workplace procedure.
Technology
Browse public learning modules for Microsoft technologies. Some exercises, progress tracking or cloud services may require a login or paid resources.
A useful first task: Choose reading-based beginner modules first and check prerequisites before activating any service.
Technology
Use openly readable lessons for web fundamentals and browser-based practice. It is a learning resource, not an accredited award.
A useful first task: Build a small accessible page and document what you changed and how you checked it.
Workplace skills
Discover occupational and workplace-preparation materials across several trades. Search and downloads do not require a contributor account.
