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

6 criteria
A.P1Describe the correct use and calibration of balances and volumetric glassware for accurate measurements.
A.P2Explain the responsible preparation of primary standard solutions and titration techniques to calculate concentrations.
B.P3Describe the use of colourimetry to prepare calibration curves and determine concentrations of unknown solutions.
B.P4Explain ecological sampling techniques used, including quadrats and microscopy, to investigate plant distribution and tissues responsibly.
C.P5Describe the use of methods of thermal energy transfer and interpret cooling curves of different liquids.
C.P6Explain how to construct and measure series and parallel electrical circuits responsibly using ammeters and voltmeters.

Merit

3 criteria
A.M1Analyse the reliability of titration results by discussing concordant titres, systematic errors and uncertainty.
C.M2Analyse the accuracy and limitations of colourimetry and ecological sampling methods when investigating biological components.
C.M3Analyse experimental data to identify factors affecting resistance in electrical components and circuits.

Distinction

3 criteria
A.D1Evaluate the effectiveness of chromatographic and melting point techniques for determining the purity of organic compounds.
B.D2Assess the significance of environmental and biological factors in influencing plant growth and biodiversity distribution.
C.D3Evaluate how renewable energy investigations optimise solar panel performance under different environmental conditions.

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.

DescribeExplainAnalyseEvaluateAssess
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.
