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.P1Explain the characteristics of the lubricants used and the process of and maintenance considerations for lubrication in two mechanical systems.
B.P2Explain the characteristics, applications and maintenance considerations of at least three types of consumable components used in two mechanical systems.
C.P3Explain the operation of and maintenance considerations for power transmission gears in two mechanical systems.
C.P4Explain the operation of and maintenance considerations for two other power transmission components in two mechanical systems.
D.P5Explain what safe working practices apply when performing two routine maintenance tasks.
D.P6Complete two routine maintenance tasks, using the correct process, on a mechanical system safely, and sustainably while inspecting the work.

Merit

4 criteria
A.M1Analyse the characteristics of lubricants used and the process of and maintenance considerations for lubrication in two different mechanical systems.
B.M2Justify the characteristics, applications and maintenance considerations of at least three types of consumable components used in two mechanical systems.
C.M3Analyse the operation of and maintenance considerations for power transmission gears and two other power transmission components in two mechanical systems.
D.M4Complete two routine maintenance tasks, using the correct process, on a mechanical system safely, sustainably and accurately, explaining the safe working practices that apply and inspecting the work.

Distinction

3 criteria
A.D1Evaluate, using language that is technically correct and of a high standard, the characteristics of lubricants used and the process of and maintenance considerations for lubrication in two different mechanical systems, suggesting improvements to the lubrication systems.
BC.D2Evaluate the characteristics and applications of at least three types of consumable and the operation of at least three types of power transmission components in two mechanical systems, including how they each contribute to the system and their maintenance considerations.
D.D3Refine, while using the correct process, two routine maintenance tasks on a mechanical system safely, sustainably, accurately and efficiently, explaining the safe working practices that apply and inspecting the work.

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.

ExplainCompleteAnalyseJustifyEvaluateRefine
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.
