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.P1Sources of information
A.P2Describe the function and operation of a mechanical system
B.P3Describe the function and operation of different components used in a mechanical system
B.P4Select components to be used in mechanical system maintenance
C.P5Sources of information
C.P6Identify mechanical system faults using fault-finding aids and techniques
D.P7Sources of information
D.P8Identify the hazards and risks before carrying out routine maintenance procedures on a mechanical system

Merit

4 criteria
A.M1Use mechanical system and component data sources
B.M2Explain the function and operation of a mechanical system and its components and the relationship between a mechanical system malfunction and component faults
C.M3Use fault rectification equipment to replace faulty components in a mechanical system
D.M4Demonstrate safety awareness and how to keep safe when carrying out routine maintenance procedures on a mechanical system

Distinction

3 criteria
AB.D1Justify the selection of components used in mechanical system maintenance
C.D2Explain the use of fault-finding aids and techniques and fault rectification equipment when identifying mechanical system faults and replacing faulty components
D.D3Explain the hazards and risks and which control measures should be used when safely carrying out routine maintenance procedures on a mechanical system

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.

SourcesDescribeSelectIdentifyUseExplainDemonstrateJustify
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 function and operation of mechanical systems and the components used in them
  • B. Select components used in mechanical systems during maintenance
  • C. Safely carry out fault-finding and fault-rectification techniques on mechanical systems and their components
  • D. Safely carry out routine maintenance procedures on mechanical systems

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.
