Mark Scheme for June 2023
,MARKING
1. Mark strictly to the mark scheme.
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 or the RM Assessor messaging system, or by email.
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 required, 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 selected 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 of
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 provided, 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.)
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 (developed) 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 the first response.
1. 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 a tick to confirm that the work has been
seen.
2. Award No Response (NR) if:
o there is nothing written in the answer space
Award Zero ‘0’ if:
o anything is written in the answer space and is not worthy of credit (this
includes text and symbols).
Team Leaders must confirm the correct use of the NR button with their markers before
live marking commences and should check this when reviewing scripts.
