Assessment criteria

Reproduced verbatim from the Pearson specification — the same grid the assignment brief carries. A unit grade is the highest band where all criteria in that band (and every band below it) are met.

Pass

5 criteria
A.P1Explain evidence and theories related to the composition of the atmosphere.
B.P2Describe evidence linking global warming to industrialisation.
B.P3Describe factors that can cause greenhouse gases.
B.P4Explain possible effects of climate change on the Earth’s atmosphere
C.P5Describe how effects of climate change could be addressed.

Merit

4 criteria
A.M1Discuss differences between early and present-day atmospheres.
B.M2Analyse evidence related to global warming and climate change.
B.M3Explain effects of human activities on the future atmosphere.
C.M4Explain methods that could help to address climate change.

Distinction

3 criteria
A.D1Evaluate evidence for, and understanding of, atmosphere changes over time.
B.D2Compare effects of pre- and post-industrial activities on the Earth’s surface and its atmosphere.
C.D3Evaluate methods used to address climate change.

Command verbs in this unit

The verb decides the depth expected — that is what separates Pass from Merit and Distinction work on the same learning aim.

ExplainDescribeDiscussAnalyseEvaluateCompare
Pearson's ladder runs Identify → Describe → Explain → Compare / Analyse → Evaluate / Justify / Assess. A Merit or Distinction criterion on the same aim always implies the Pass beneath it: an “evaluate” answer that never first “explains” fails, however polished it reads. Hover a verb for what it demands.

How checkb.tech checks this unit

Upload a learner's submission and checkb.tech reads it against exactly these criteria, reporting each one as met, partly met, or not met — with the evidence that informed the verdict cited, so every call is auditable.

The check runs against the official Pearson documents for this unit, and identical evidence always produces an identical result — the same script gets the same verdict every time.

It never awards a grade. You stay the assessor: confirm, dismiss, or act on every criterion before your assessment decision is final.
