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 technology and characteristics of at least two additive processes used to manufacture components safely and sustainably.

B.P2Explain how the design of at least two components manufactured using traditional processes could be improved and adapted for additive processes

B.P3Explain what finishing processes could be applied to two components if they were manufactured using additive processes instead of traditional manufacturing processes.

C.P4Design a component encompassing a hollow section and/or a support that can be manufactured safely using an additive process.

C.P5Manufacture a component encompassing a hollow section and/or a support, safely using an additive and suitable finishing process.

C.P6Check the finished component for dimensional accuracy against the original design.

Merit

4 criteria

A.M1Compare the technology and characteristics of at least two additive processes used to manufacture components safely and sustainability.

B.M2Analyse how the design of at least two components manufactured using traditional processes could be improved and adapted for additive processes, including a justification for the finishing processes required.

C.M3Design a component encompassing a hollow section and/or a support that can be manufactured safely and effectively using an additive process.

C.M4Manufacture a component encompassing a hollow section and/or a support safely and effectively using an additive and suitable finishing processes, while checking the finished component for dimensional accuracy.

Distinction

3 criteria

A.D1Justify, using vocational and high-quality written language, the technology and characteristics of at least two additive processes used to manufacture components safely and sustainably

B.D2Evaluate how the design of at least two components manufactured using traditional processes could be improved and adapted for additive processes, including a justification for the finishing processes required.

C.D3Optimise the development of a component encompassing a hollow section and/or a support using additive manufacturing and finishing processes safely, effectively and efficiently, while checking the finished component for dimensional accuracy.

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.

ExplainDesignManufactureCheckCompareAnalyseJustifyEvaluateOptimise

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.
