Unit 1 Engineering Principles Sample Assessment Materials Mark Scheme
General marking guidance All learners must receive the same treatment. Examiners must mark the first learner
in exactly the same way as they mark the last. Mark schemes should be applied positively. Learners must be rewarded for what
they have shown they can do rather than be penalised for omissions. Examiners should mark according to the mark scheme, not according to their
perception of where the grade boundaries may lie. All marks on the mark scheme should be used appropriately. All the marks on the mark scheme are designed to be awarded. Examiners should
always award full marks if deserved, i.e. if the answer matches the mark scheme. Examiners should be prepared to award zero marks if the learner’s response is not worthy of credit according to the mark scheme.
Where some judgement is required mark schemes will provide the principles by which marks will be awarded and exemplification may be limited.
When examiners are in doubt regarding the application of the mark scheme to a learner’s response, the team leader must be consulted.
Crossed-out work should be marked UNLESS the learner has replaced it with an alternative response.
Specific marking guidance for levels-based mark schemes* Levels-based mark schemes (LBMS) have been designed to assess learner work holistically. They consist of two parts: indicative content and levels-based descriptors. Indicative content reflects specific content-related points that learners might make. Levels-based descriptors articulate the skills that learners are likely to demonstrate in relation to the skills being assessed in the question. The levels represent the progression of these skills. When using a levels-based mark scheme, the ‘best fit’ approach should be used.
Examiners should first make a holistic judgement on which band most closely matches learners’ response and place it within that band. Learners will be placed in the band that best describes their answer.
The mark awarded within the band will be decided based on the quality of the answer in response to the level descriptor, and will be modified according to how securely all traits are displayed at that band.
