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

8 criteria
A.P1Explain the features and functions of typical hardware components found in two contrasting computer systems.
A.P2Explain the features and functions of the software used in two contrasting computer systems.
A.P3Explain the security threats, vulnerabilities and protection measures in two contrasting computer systems.
B.P4Explain, using examples, how different types of data are represented in a microprocessor and include number conversions and binary manipulation
C.P5Explain the standard architecture of a microprocessor.
C.P6Explain how an instruction is typically executed in a microprocessor.
D.P7Design, including a test plan, the solution to an onscreen computer program using structured tools.
D.P8Build and test a functional computer program to solve an onscreen problem.

Merit

4 criteria
A.M1Compare the suitability of technology and security protection measures found in two contrasting computer systems.
B.M2Discuss accurately, using examples, how data is represented and manipulated in a microprocessor.
C.M3Discuss accurately the standard architecture of a microprocessor and how an instruction is typically executed in a microprocessor
D.M4Develop a functional onscreen computer program that operates as intended, while documenting alternative design solutions and embedding commentary.

Distinction

3 criteria
A.D1Evaluate, using language that is technically correct and of a high standard, the suitability of the technology and security protection measures found in two contrasting computer systems, suggesting possible improvements.
BC.D2Critically analyse the operation of a microprocessor demonstrating how data is represented and manipulated and how the architecture affects performance.
D.D3Optimise the efficiency of a functional onscreen computer program that operates as intended and contains detailed commentary throughout.

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.

ExplainDesignBuildCompareDiscussDevelopEvaluateCriticallyOptimise
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.
