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 design requirements for below ground drainage systems for surface water and foul water from buildings.
A.P2Explain methods of treating domestic sewerage in a given situation.
B.P3Explain the benefits associated with the separating of different types of solid domestic waste
B.P4Explain how different requirements and constraints impact on the methods used for the disposal of solid domestic waste.
C.P5Explain the relationships between factors that influence the water purification process
C.P6Explain the factors that contribute towards the use of different approaches to remove hardness from water.

Merit

3 criteria
A.M1Assess the design requirements for below ground drainage systems and treatment of domestic sewerage, using calculations to support decisions for a given situation.
B.M2Discuss methods of disposal of solid domestic waste, including the benefits of separating materials and how decisions are influenced by requirements and constraints for a given situation.
C.M3Discuss the influence of design factors in the selection of methods to purify and distribute drinking water in a given

Distinction

3 criteria
A.D1Justify the suitability of alternative approaches to below ground water drainage and domestic sewerage treatment, including reference to calculations, maintenance requirements and testing for a given situation.
B.D2Evaluate how requirements and constraints impact on the selection of methods for the sorting and disposal of solid domestic waste for a given situation.
C.D3Evaluate how availability of sources, purification, storage and distribution requirements impact on the supply of drinking water in 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.

ExplainAssessDiscussJustifyEvaluate
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. Understand below ground drainage systems and methods for treating sewerage
  • B. Examine methods for disposing of solid domestic waste
  • C. Examine the processes used to produce and distribute drinking water

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.
