General Marking Guidance

• All learners m ust receive the sam e t reatm ent . Exam iners m ust

m ark the first learner in exact ly the sam e way as they m ark

the last .

• Mark schem es should be applied posit ively. Learners m ust be

rewarded for what they have shown they can do rather than

penalised for om issions.

• Exam iners should m ark according to the m ark schem e not

according to their percept ion of where the grade boundaries

m ay lie.

• There is no ceiling on achievem ent . All m arks on the m ark

schem e should be used appropriately.

• All the m arks on the m ark schem e are designed to be

awarded. Exam iners should always award full m arks if

deserved, i.e. if the answer m atches the m ark schem e.

Exam iners should also be prepared to award zero m arks if the

learner ’s response is not worthy of credit according to the

m ark schem e.

• Where som e judgem ent is required, m ark schem es will provide

the pr inciples by which m arks will be awarded and

exem plificat ion m ay be lim ited.

• When exam iners are in doubt regarding the applicat ion of the

m ark schem e to a learner’s response, the team leader m ust be

consulted.

• Crossed out work should be m arked UNLESS the learner has

replaced it with an alternat ive response.

• Mark schem es will indicate within the table where, and which

st rands of QWC, are being assessed. The st rands are as

follows:

i) Ensure that text is legible and that spelling, punctuat ion and

gram m ar are accurate so that m eaning is clear

ii) Select and use a form and style of writ ing appropriate to

purpose and to com plex subject m at ter

iii) Organise inform at ion clearly and coherent ly, using specialist

vocabulary when appropriate.
