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 factors that need to be considered when designing heating
B.P2Produce a pipework layout for a domestic situation that includes the positioning and requirements of all key components.
B.P3Assess the required heat output for the emitters in each room for a domestic property.
B.P4Assess the boiler output requirements for a given domestic property.
C.P5Select a boiler to meet the needs of a given domestic property.
C.P6Produce schedules of materials and equipment that meet some of the needs of a given domestic property.

Merit

3 criteria
A.M1Analyse the factors that need to be considered when designing heating
B.M2Produce a detailed heating design that meets the needs of a given
C.M3Justify the selection of a boiler, materials and equipment that meets most of the needs of a given domestic property.

Distinction

3 criteria
A.D1Evaluate the factors that need to be considered when designing heating
B.D2Produce a comprehensive heating design that fully meets the needs of a given domestic property.
C.D3Evaluate the selection of a boiler, materials and equipment that fully meets the needs of a given domestic property.

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.

ExplainProduceAssessSelectAnalyseJustifyEvaluate
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 the design requirements for a LTHW system
  • B. Undertake the design of a LTHW installation for a domestic property
  • C. Develop a specification for materials, components and ancillary equipment for a domestic LTHW system

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.
