Learning outcomes
Assessment Objective B: handling, applying and evaluating information. Use the outcome map to find the explanation for a particular syllabus requirement.
These labels map assessment skills and practical techniques, separately from the numbered theory outcomes. P, MMO, PDO and ACE are practical skill areas; T labels follow the listed techniques, and B labels follow H1 Assessment Objective B.

B1 Organise relevant information
- Locate and present information from supplied sources
Read unfamiliar data with a purposeTurn measurements into a graph or calculation
B2 Select what matters
- Distinguish relevant evidence from extraneous detail
B3 Manipulate and translate data
- Move between numerical, symbolic and graphical forms
- Use units and suitable precision
B4 Find patterns and draw inferences
- Analyse trends and report conclusions supported by measurements
Turn measurements into a graph or calculationEvaluate evidence and explain the direction of an error
B5 Explain relationships
- Connect a measured pattern to a chemical mechanism or principle
B6 Apply chemistry to unfamiliar situations
- Use supplied definitions and familiar principles without relying on a familiar substance name
Read unfamiliar data with a purposeEvaluate evidence and explain the direction of an error
B7 Integrate knowledge
- Combine rate, reacting amount and measurement conditions in one argument
Read unfamiliar data with a purposeEvaluate evidence and explain the direction of an error
B8 Evaluate information and hypotheses
- Separate claim and evidence
- Recognise confounding variables, scatter and systematic error
B9 Justify a conclusion or action
- Use specific evidence and a causal chain
- Target an improvement to a real limitation
B10 Recognise model limitations
- State conditions and assumptions
- Limit a conclusion to the measured range and supported comparison
