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

10 criteria
A.P1Explain the principles and production of a laser and how it is used in diagnosis and treatment.
A.P2Explain the principles and production of imaging techniques used in
A.P3Describe four diagnostic techniques used in haematology.
A.P4Describe the screening procedures involved in preventing the transmission of blood-borne infections.
B.P3Explain the principles and production of external and internal radiotherapy.
B.P4Explain the principles and production of x-ray images, CT and CAT
B.P5Explain the causes of cell injury.
C.P5Explain the risks and side effects of ionising and non-ionising diagnosis and treatment techniques for operators and service users.
C.P6Explain the safety precautions for x-ray and MRI use for operators and
C.P7Describe how two biochemical tests are used to monitor the biochemistry of the human body.

Merit

6 criteria
A.M1Discuss the clinical uses of blood products and the reasons for screening them before use.
A.M2Analyse the screening procedures involved in preventing the transmission of blood-borne infections.
B.M2Analyse the suitability of different ionising radiation techniques used for diagnosis and treatment in relation to a specific service user.
B.M3Analyse how cell pathology is used in disease identification.
C.M3Analyse the risks and side-effects to operators and service users of
C.M4Assess how biochemical tests are used to monitor the human body.

Distinction

5 criteria
A.D1Evaluate the clinical use of blood products and the screening procedures involved in preventing the transmission of blood-borne infections.
AB.D1Evaluate the choice of ionising and non-ionising radiation diagnosis and treatment techniques in relation to a specific service user.
BC.D2Evaluate the effectiveness of cell pathology used in conjunction with biochemical investigations as a diagnostic tool.
C.D2Evaluate the health and safety precautions for service users and operators using ionising and non-ionising diagnosis and treatment techniques in relation to a specific service user.
C.D3Justify a choice of ionising and non-ionising diagnosis technique with

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.

ExplainDescribeDiscussAnalyseAssessEvaluateJustify
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 how non-ionising radiation instrumentation techniques are used for diagnosis and treatment of the human body
  • B. Understand how ionising radiation instrumentation techniques are used for diagnosis and treatment of the human body
  • C. Explore the risks, side effects and health and safety precautions for ionising and non-ionising radiation.

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.
