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

8 criteria
A.P1Describe the characteristics of the six main types of pathogens and a disease caused by each.
A.P2Explain causes of non-infectious diseases in humans.
B.P2Explain the stages involved in the human respiratory pathway
B.P3Carry out an investigation involving the effect of activity on respiration in humans
B.P4Describe ways infectious diseases can be prevented from spreading.
C.P5Describe causes and effects of three environmental diseases.
C.P6Carry out an investigation into a factor that affects the rate of photosynthesis.
C.P7Explain components of specific and non-specific defences for protecting the human body.

Merit

4 criteria
A.M1Explain the links between the structure and function of biological molecules and their role in living organisms.
B.M2Analyse primary and secondary data to explain the effect of activity on respiration.
B.M3Analyse methods used to reduce the effects of environmental pollutants.
C.M4Analyse primary and secondary data to explain the outcomes of an investigation into a factor that affects the rate of photosynthesis.

Distinction

4 criteria
A.D1Analyse how an infectious and non-infectious disease may progress over time and the effects this may have on affected individuals.
B.D2Evaluate the effects of harmful substances on the efficiency of respiration.
BC.D2Evaluate the role of organisations in limiting the spread of infectious diseases and environmental pollution. [Shared with Task 2]
C.D3Evaluate the roles of cell-mediated and humoral responses to pathogens.

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.

DescribeExplainCarryAnalyseEvaluate
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.
