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 selection of a building service control system, its components and some of its operational features for a given scenario.
B.P2Produce a systems diagram for a simple building services control system.
B.P3Describe the sensors, actuators and controllers to be installed for a simple building services control systems, for a given scenario.
C.P4Select an appropriate building services control system for a given scenario.
C.P5Select the appropriate control components for use within a building services control system for a given scenario.
C.P6Explain the behaviour of the controls selected for a simple building control system, for a given scenario.

Merit

3 criteria
A.M1Assess the selection of a building services control system, its components and most of its operational features for a given scenario.
B.M2Produce a detailed control system design that mostly meets the requirements of the building services control system.
C.M3Select an appropriate building services control system and control components, including detailed control strategy and detailed schematic drawings, for a given scenario

Distinction

3 criteria
A.D1Justify the selection of a building services control system, its components and all of its operational features, for a given scenario.
B.D2Produce a comprehensive system design that fully meets the requirements of a building control system, for a given scenario
C.D3Justify the selection of an appropriate building services control system and control components, including details of the control strategy and schematic drawings which clearly communicate the designs, for a given scenario.

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.

ExplainProduceDescribeSelectAssessJustify
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.
