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

7 criteria
A.P1Explain the principles that underpin the design of different types of bridges
A.P2Explain the impact that material choice can have on the design of bridges
A.P3Explain the impact of different traffic levels on the design of a bridge
B.P4Explain the methods that can be used to construct tunnels.
B.P5Explain the impact of ground conditions on the design of tunnels.
C.P6Explain the approaches used to provide coastal protection
C.P7Describe the reasons why cofferdams and caissons are used in civil engineering projects

Merit

4 criteria
A.M1Discuss the benefits and drawbacks of different approaches to bridge construction in a given situation
A.M2Discuss the impact of the traffic levels on bridge design in a given situation
B.M3Discuss the suitability of alternative types of tunnel for a given situation.
C.M4Discuss the suitability of alternative approaches to coastal protection for a given situation

Distinction

3 criteria
A.D1Evaluate the interaction between design considerations for a bridge in a given situation
B.D2Evaluate the different approaches that can be taken to construct a tunnel for a given situation.
C.D3Evaluate the interaction between design parameters, methods of construction and approaches to coastal protection for a given situation

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.

ExplainDescribeDiscussEvaluate
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.
