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

4 criteria
A.P1Identify electronic components from their symbols and their physical appearance.
B.P2Safely construct working electronic circuits.
B.P3Safely construct a useful working electronic system that meets an identified purpose.
C.P4Carry out checks and electrical measurements safely to test circuits.

Merit

4 criteria
A.M1Describe the function of electronic components.
B.M2Calculate expected values of voltage and current for different places in electronic circuits.
B.M3Explain how the electronic system meets its purpose and identify any weaknesses.
C.M4Discuss the importance of reliability of measurements on circuits.

Distinction

3 criteria
A.D1Evaluate the advantages and disadvantages of using integrated circuits.
B.D2Evaluate an electronic system and suggest improvements.
C.D3Evaluate electrical measurements of voltages and currents against calculated values.

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.

IdentifySafelyCarryDescribeCalculateExplainDiscussEvaluate
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

  • B. Build electronic circuits and systems safely
  • C. Check, measure and test electronic circuits

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.
