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.P1Determine graphically the support reactions and primary forces acting in the members of a pin-jointed, statically determinate framed structure.

A.P2Calculate the support reactions and primary forces acting in the components of a pin-jointed, statically determinate framed structure.

B.P3Conduct experiments safely to determine the shear forces and bending moments in simply supported and cantilever beams when subjected to simple loading.

B.P4Explain, using experimental results and theoretical calculations, the shear forces and bending moments in simply supported and cantilever beams when subjected to simple loading.

C.P5Calculate the axial stress produced in a rigidly held simple structural component when subjected to a combination of axial loading and temperature change.

C.P6Calculate the maximum bending stress, the factor of safety in operation and minimum radius of curvature for a simply supported beam carrying concentrated and uniformly distributed loads.

C.P7Calculate the maximum shear stress for a single shear lap joint and a double shear butt joint for given loading.

Merit

5 criteria

A.M1Determine accurately the magnitude and nature of the primary forces acting in the components of a pin-jointed, statically determinate framed structure.

B.M2Conduct experiments accurately to determine the shear forces and bending moments in simply supported and cantilever beams when subjected to simple and complex loading

B.M3Analyse, using experimental results and theoretical calculations, the shear forces and bending moments in simply supported and cantilever beams when subjected to simple and complex loading.

C.M4Analyse accurately the axial stress produced in a rigidly held complex structural component when subjected to a combination of axial loading and temperature change.

C.M5Develop accurately a design for a complex structure that does not fail when subject to bending and shear loading.

Distinction

3 criteria

A.D1Demonstrate accurately the most appropriate method for finding the forces in the central members of a pin-jointed framed structure, justifying the rationale.

B.D2Evaluate the simple and complex loads acting on simply supported and cantilever beams, comparing the results from safely conducted experiments and theoretical calculations, and suggest improvements to the experimental method used.

C.D3Optimise the physical parameters of a structure ensuring it is fit for purpose when subject to axial, bending and shear loading.

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.

DetermineCalculateConductExplainAnalyseDevelopDemonstrateEvaluateOptimise

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.
