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

4 criteria
A.P1Identify metallic, covalent and ionic chemical bonding from given physical properties of chemical substances.
A.P2Describe the structure of metallic and non-metallic elements, the structure of metallic, covalent and ionic chemical bonding and the effect of bond type on the physical properties of chemical substances.
B.P3Describe an engineering application of an electrochemical process.
B.P4Explain an engineering application of a chemical and an electro-chemical process.

Merit

2 criteria
A.M1Compare the structure of metallic and non-metallic elements, the structure of metallic, covalent and ionic chemical bonding and their effects on the physical properties of chemical substances.
B.M2Evaluate an engineering application of a chemical and an electrochemical process.

Distinction

2 criteria
A.D1Sources of information
B.D2Sources of information

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.

IdentifyDescribeExplainCompareEvaluateSources
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.

Learning aims

  • A. Investigate the atomic structure and the types of chemical bonds found in common substances.
  • B. Understand the engineering applications of some chemical and electro-chemical processes

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.
