Section 1: Introduction
This booklet is for use by teachers who wish to be accredited to carry out coursework assessment inCambridge IGCSE Chemistry, Physical Sciences, Combined Science or Co-ordinated Sciences. It should be
used in conjunction with the IGCSE Science Coursework Training Handbook (Part 1): Guidance booklet.
1.1 Is this the right booklet for me?
This booklet is one of three entitled IGCSE Coursework Training Handbook (Part 2): Teacher Accreditation.
The other two cover IGCSE Biology and IGCSE Physics.
You should use this booklet if you wish to enter candidates for Paper 4, Coursework, in IGCSE Chemistry,
Combined Science or Co-ordinated Sciences.
Note that, if you teach Combined Science or Co-ordinated Sciences, you do notneed to complete tasks in
each of the subject areas. You may choose the one Biology, Chemistry or Physics with which you are
most comfortable, and submit tasks from just that one subject area.
If you teach Physical Science, you can complete tasks contained in the Part 2 Coursework Training
Handbooks for Teacher Accreditation for eitherPhysics orChemistry.
1.2 How to use this booklet
This booklet contains several tasks that you need to complete in order to become accredited to carry out
coursework assessment in any of the sciences.
In order to gain accreditation you should:
Work carefully through the IGCSE Science Coursework Training Handbook (Part 1): Guidance booklet,
which is available electronically on Teacher Support and can be ordered as hard copy from the
Cambridge Publication Catalogue. It is essential that you are thoroughly familiar with the contents of that
booklet before you begin to work through the tasks in this booklet.
Complete each of the tasks in this booklet.
Copy and complete the accreditation forms at the back of the book, checking that you have met all the
requirements of the accreditation tasks.
Send your completed forms, and all of the documents that form part of your submission, to the addressindicated on the forms.
Allow 46 weeks for your work to be checked by a coursework assessor. You will receive feedback on what
you have submitted. If there are any problems with your work that suggest you may not quite be ready
to assess coursework, you may be asked to resubmit. You may apply as many times as you wish to gain
accreditation, although there is a small charge on each occasion.

Section 2: Task One, writing worksheets and mark
schemes
Before you begin this task:
re-read Section 6: Constructing worksheets and mark schemes, in theIGCSE Science Coursework
Training Handbook (Part 1): Guidance booklet
make sure that you have the assessment criteria for awarding marks for C1, C2, C3 and C4 with you for
reference. You will find these in your IGCSE syllabus, or in the Part 1 booklet.
There are three parts to this task: 1a, 1b and 1c.
Note: if possible, try to ensure that your worksheets are on topics that differ from those in the Part 1
booklet, and those in this booklet.
Task 1a
Write a worksheet and mark scheme that you could use to assess skill C1, and that would allow access
to the full range of marks. You may choose to use either a tick list mark scheme, or a descriptive mark
scheme.
Task 1b
Write one worksheet that you could use to assess skills C2 and C3, and that would allow access to the full
range of marks in each of the two skills. Write a mark scheme for C2, and another for C3.
Task 1c
Write a worksheet and mark scheme that you could use to assess skill C4, and that would allow access to
the full range of marks.
