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.
