OCR (Oxford Cambridge and RSA) is a leading UK awarding body, providing a wide range of
qualifications to meet the needs of candidates of all ages and abilities. OCR qualifications
include AS/A Levels, Diplomas, GCSEs, Cambridge Nationals, Cambridge Technicals,
Functional Skills, Key Skills, Entry Level qualifications, NVQs and vocational qualifications in
areas such as IT, business, languages, teaching/training, administration and secretarial skills.
It is also responsible for developing new specifications to meet national requirements and the
needs of students and teachers. OCR is a not-for-profit organisation; any surplus made is
invested back into the establishment to help towards the development of qualifications and
support, which keep pace with the changing needs of today’s society.
This mark scheme is published as an aid to teachers and students, to indicate the requirements
of the examination. It shows the basis on which marks were awarded by examiners. It does not
indicate the details of the discussions which took place at an examiners’ meeting before marking
commenced.
All examiners are instructed that alternative correct answers and unexpected approaches in
candidates’ scripts must be given marks that fairly reflect the relevant knowledge and skills
demonstrated.
Mark schemes should be read in conjunction with the published question papers and the report
on the examination.

H446/01 Mark Scheme June 2024
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 posted on the RM Cambridge
Assessment Support Portal http://www.rm.com/support/ca
3. Log-in to RM assessor and mark the required number of practice responses (“scripts”) and the number of required standardisation responses.
YOU MUST MARK 10 PRACTICE AND 10 STANDARDISATION RESPONSES BEFORE YOU CAN BE APPROVED TO MARK LIVE SCRIPTS.
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% (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.
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.
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)

H446/01 Mark Scheme June 2024
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.
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 a tick to confirm that the work has been seen.
7. Award No Response (NR) if:
• there is nothing written in the answer space
Award Zero ‘0’ if:
• 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.
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.
If you have any questions or comments for your team leader, use the phone, the RM assessor messaging system, or e-mail.
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 weaknesses. Constructive criticism of the
question paper/mark scheme is also appreciated.
10. For answers marked by levels of response:
