Course handbook

Know the route before you begin.

Here’s what you’ll need and what you’ll make. You can return to this guide during any lesson.

Who this is for

Learners ages 14+ and adults ready for the named prerequisite; no employment or private records required.

Prepare before lesson one

Review the existing everyday computer skills course.
Use any available browser and keyboard; a native screen reader is optional. The documented comparison pathway can be completed when a reader is unavailable.
Use only fictional task data. Do not disclose disability, diagnosis, passwords, or private learner work.

Your final project

Finish with proof you can use.

A personal non-sensitive task card and scoped navigation test using text size, zoom, keyboard and an available screen reader, with a truthful fallback comparison when a reader is unavailable.

What to include

Create a task-based access choice with available/unavailable tools and no sensitive personal data.
Retain baseline/adjusted settings and observed information/control access, with restoration recorded.
Complete and document the keyboard task or its exact observed barrier.
Record an actual native setup/tutorial or a clearly labeled documentation-based fallback.
Produce a task outcome comparison that separates actual observations, expected structure, and unavailable checks.
Deliver a non-sensitive repeatable access plan with actual results, alternate route, and exact verification limits.

Review and revise

Use these criteria to check your work and choose what to improve.

The implementation or declared simulation follows the supplied contract and retains inspectable original inputs.
Normal, boundary and rejected cases are recorded with expected versus observed results.
The changed case has a correct explanation and does not rely on hidden state.
The project includes source, outputs, instructions and honest tool, privacy and verification limits.

Three ideas to help you along the way

Three useful ideas

The rules behind the steps.

State the contract

Name inputs, permitted states and observable outputs before editing the implementation.

Preserve the evidence

Keep the actual source, changed input and expected/observed record so someone can repeat the work.

Test the boundary

Check a rejection or changed case and distinguish local practice from real service or native-tool behavior.

What do these words mean?

Key words

Key terms worth knowing.

focus: The current keyboard interaction target.
magnification: Enlarging the displayed page or view.
screen reader: Software that exposes structure and controls through speech or braille.
modifier: A configured key or key combination used with commands.
fallback comparison: A clearly labeled alternative that does not claim unavailable tool execution.
