Training in Scientific Evidence Examination and Interpretation

General Courses

Case Assessment and Interpretation (CAI)

The basic principles of interpretation of evidence apply to all areas of forensic science. PFS provide training on how to arrive at a logically based expert opinion using the concepts of Case Assessment and Interpretation both to support the investigative phase and for evidence at court. Development of CAI was led by PFS’s Ian Evett who was awarded a CBE in 2016. CAI training can be provided as a general course or specific to evidence type.

Expert Witness and Court Room Skills

How to present evidence in written and oral form. Covers the criminal court system, roles of court officials, evidence interpretation, duties of expert witnesses, rules of evidence, the required attitudes and behaviours, principles of courtroom dynamics and communication. Includes statement writing exercises, cross-examination exercises and a full witness box exercise. It does not test academic background and can be delivered for any evidence type.
