MARKING INSTRUCTIONS
PREPARATION FOR MARKING
RM ASSESSOR
1. Make sure that you have accessed and completed the relevant training packages for on-screen marking: RM Assessor Online Training:
OCR Essential Guide to Marking.
2. Make sure that you have read and understood the mark scheme and the question paper for this unit. These are available in RM Assessor
3. Log-in to RM Assessor and mark the required number of practice responses (“scripts”) and the required number of standardisation
responses.
MARKING
1. Mark strictly to the mark scheme.
3
,H240/01 Mark Scheme June 2025
2. Marks awarded must relate directly to the marking criteria.
3. The schedule of dates is very important. It is essential that you meet the RM Assessor 50% and 100% (traditional 40% Batch 1 and 100%
Batch 2) deadlines. If you experience problems, you must contact your Team Leader (Supervisor) without delay.
4. If you are in any doubt about applying the mark scheme, consult your Team Leader by telephone , email or via the RM Assessor
messaging system.
5. Crossed-Out Responses
Where a candidate has crossed out a response and provided a clear alternative then the crossed-out response is not marked. Where no
alternative response has been provided, examiners may give candidates the benefit of the doubt and mark the crossed-out response where
legible.

Rubric Error Responses – Optional Questions
Where candidates have a choice of question across a whole paper or a whole section and have provided more answers than requir ed, then
all responses are marked and the highest mark allowable within the rubric is given. Enter a mark for each question answered into RM
Assessor, which will select the highest mark from those awarded. (The underlying assumption is that the candidate has penalised
themselves by attempting more questions than necessary in the time allowed.)
Multiple-Choice Question Responses
When a multiple-choice question has only a single, correct response and a candidate provides two responses (even if one of these
responses is correct), then no mark should be awarded (as it is not possible to determine which was the first response select ed by the
candidate).
When a question requires candidates to select more than one option/multiple options, then local marking arrangements need to ensure
consistency of approach.
Contradictory Responses
When a candidate provides contradictory responses, then no mark should be awarded, even if one of the answers is correct.
Short Answer Questions (requiring only a list by way of a response, usually worth only one mark per response)
Where candidates are required to provide a set number of short answer responses then only the set number of responses should be
marked. The response space should be marked from left to right on each line and then line by line until the required number o f responses
have been considered. The remaining responses should not then be marked. Examiners will have to apply judgement as to whether a
‘second response’ on a line is a development of the ‘first response’, rather than a separate, discrete response. (The underlying assumption
is that the candidate is attempting to hedge their bets and therefore getting undue benefit rather than engaging with the question and giving
the most relevant/correct responses.)
Short Answer Questions (requiring a more developed response, worth two or more marks)
If the candidates are required to provide a description of, say, three items or factors and four items or factors are provide d, then mark on a
similar basis – that is downwards (as it is unlikely in this situation that a candidate will provide more than one response in each section of
the response space).

, H240/01 Mark Scheme June 2025
Longer Answer Questions (requiring a developed response)
Where candidates have provided two (or more) responses to a medium or high tariff question which only required a single (deve loped)
response and not crossed out the first response, then only the first response should be marked. Examiners will need to apply professional
judgement as to whether the second (or a subsequent) response is a ‘new start’ or simply a poorly expressed continuation of t he first
response.
6. Always check the pages (and additional objects if present) at the end of the response in case any answers have been continued there. If
the candidate has continued an answer there, then add the annotation ‘SEEN’ to confirm that the work has been seen and mark any
responses using the annotations in section 11.
7. There is a NR (No Response) option. Award NR (No Response):
- if there is nothing written at all in the answer space
- OR if there is a comment which does not in any way relate to the question ( e.g., ‘can’t do’, ‘don’t know’)
- OR if there is a mark (e.g., a dash, a question mark) which is not an attempt at the question.
Note: Award 0 marks – for an attempt that earns no credit (including copying out the question).
8. The RM Assessor comments box is used by your Team Leader to explain the marking of the practice responses. Please refer to these
comments when checking your practice responses. Do not use the comments box for any other reason.
9. Assistant Examiners will send a brief report on the performance of candidates to their Team Leader (Supervisor) via email by the end of
the marking period. The report should contain notes on particular strengths displayed as well as common errors or weaknes ses.
Constructive criticism of the question paper/mark scheme is also appreciated .
10. For answers marked by levels of response: Not applicable in F501
To determine the level – start at the highest level and work down until you reach the level that matches the answer
To determine the mark within the level, consider the following
