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.P1Describe half-life in terms of radioactive decay.
A.P2Describe the different types of ionising radiation.
A.P3Describe the problems associated with the use of radioactive isotopes.
A.P4Describe how controllable nuclear fission and fusion reactions are.
B.P5Describe methods of producing a.c. and d.c.
B.P6Use V = IR to predict values in electric circuit investigations.
B.P7Describe how electricity is transmitted to the home or industry.
C.P8Describe the structure of the Universe and our Solar System.
C.P9Describe the suitability of different methods for observing the Universe.
C.P10Identify evidence that shows the dynamic nature of the Universe.

Merit

7 criteria
A.M1Use graphs to explain radioactive decay and half-life.
A.M2Compare the benefits and drawbacks of using radioactive isotopes in the home or workplace.
A.M3Describe the environmental impact of radioactive material from nuclear fission reactors released into the environment.
B.M4Compare the efficiency and environmental impact of electricity generated by different sources.
B.M5Assess, in qualitative terms, ways to minimise energy losses when transmitting electricity.
C.M6Describe how the Universe and the Solar System were formed.
C.M7Explain how evidence shows that the Universe is changing.

Distinction

5 criteria
A.D1Calculate the half-life of radioactive isotopes.
A.D2Justify the selection of a radioactive isotope for a given use within the home or workplace.
A.D3Evaluate the environmental impacts of a nuclear fission reactor accident, in terms of half-life.
B.D4Assess, in quantitative terms, ways to minimise energy losses either when transmitting electricity or when transforming electricity into other forms for consumer applications.
C.D5Evaluate the evidence leading to the Big Bang theory of how the Universe was formed.

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.

DescribeUseIdentifyCompareAssessExplainCalculateJustifyEvaluate
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. Know how electrical energy produced from different sources can be transferred through a country's system operator of electricity and gas supply to homes and industry.
  • C. Know the components of the Solar System, the way the Universe is changing and the methods we use to explore space

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.
