Evaluation with Claude

In Claude Workflow Practice, the way a learner handles evaluation shapes how Claude is used and evaluated. Evaluation compares behaviour on representative tasks using explicit criteria. This intermediate lesson focuses on a decision or output that another person can inspect.

Learning objectives

Explain evaluation in the context of Claude Workflow Practice.
Apply Claude to a bounded practical task.
Evaluate the result using explicit quality criteria.

Evaluation: from context to evidence

Evaluation connects bounded input to a reviewed output in Claude Workflow Practice.

Bounded input

Define the purpose, intended user and Claude constraints.

Evaluation

Build a test set with pass conditions, edge cases and failure categories.

Reviewed output

Compare the observed result with a normal case, boundary case and stated limitation.

Takeaway: Evaluation is credible only when the result can be traced back to its purpose, inputs and constraints. Evaluation is the decision layer between the starting context and evidence that the result is fit for purpose.

Evaluation compares behaviour on representative tasks using explicit criteria. For Claude, distinguish performing an operation from demonstrating that it suits the stated purpose. Build a test set with pass conditions, edge cases and failure categories. Record assumptions that could change the conclusion.

Apply evaluation deliberately

State the Claude Workflow Practice task and the decision it supports.
Prepare a small Claude case with a known input and difficult boundary.
Build a test set with pass conditions, edge cases and failure categories.
Compare the observed result with the expected behaviour and explain differences.
Save the evidence, limitation and next action in a review record.

evaluation evidence record
Review point	Evidence
Purpose	The specific Claude outcome and intended user
Method	The evaluation decision, input and version or context
Result	Observed output plus a checked boundary case
Limitation	What the result does not establish and the next safe action

Common mistakes

Using Claude before defining what evaluation must achieve.
Checking only the easiest Claude Workflow Practice example.
Reporting a result without its input, assumptions or limitation.

Practice activity

Apply the lesson

For Claude Workflow Practice, complete a bounded Claude task demonstrating evaluation. Keep the original input, numbered method, normal test, boundary test, observed results and a 100-word self-review naming one limitation and next improvement.

Check your understanding

In Claude Workflow Practice, which evidence best supports a evaluation result produced with Claude?

A polished Claude output without its input The input, expected behaviour, normal and boundary results, and a limitation A screenshot showing the tool opened A claim that the method always works

Lesson summary

For Claude Workflow Practice, evaluation means: Evaluation compares behaviour on representative tasks using explicit criteria.
A credible Claude result includes a checked boundary, not only a successful example.
The next lesson builds on this evaluation evidence record.
