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.P1Capture the circuit schematic and simulate the correct operation of at least one circuit from each type of single function analogue circuit.

B.P2Build one circuit from each type of single function analogue circuit safely and determine the characteristics of each.

B.P3Explain, using theoretical calculations and test results, the correct operation of one circuit from each type of single function analogue circuit and suggest suitable applications.

C.P4Design a modified single function analogue circuit, using calculations of component values and simulation methods.

C.P5Build and test safely a permanently constructed modified single function circuit.

D.P6Explain how health and safety, design, build and general engineering skills were effectively applied during the development of the analogue circuit.

D.P7Explain how relevant behaviours were effectively applied during the development of an analogue circuit.

Merit

5 criteria

B.M1Capture the circuit schematic and simulate accurately at least one circuit from each type of analogue circuit.

B.M2Build at least one circuit from each type of analogue circuit and test the characteristics accurately.

B.M3Analyse, using theoretical calculations and test results, the correct operation of at least one circuit from each type of analogue circuit.

C.M4Develop accurately a modified single function circuit that operates as intended, while documenting alternative solutions.

D.M5Recommend improvements to the development of the analogue circuit and to the relevant behaviours applied.

Distinction

3 criteria

AB.D1Evaluate, using language that is technically correct and of a high standard, the operation of at least two circuits from each type of analogue circuit, comparing the theoretical calculations and results from safely conducted experiments and simulations.

C.D2Refine, during the process, the operation of a modified single function circuit to improve its performance.

D.D3Demonstrate consistently good technical understanding and analysis of analogue circuit development, including the application of relevant behaviours and general engineering skills to a professional standard.

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.

CaptureBuildExplainDesignAnalyseDevelopRecommendEvaluateRefineDemonstrate

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.
