Do I need to send diplomas with my application?
A copy of the diploma is always needed, usually at the very beginning of the application. Authenticity of documentation is rarely necessary, except for regulated professions for which registration is required, such as doctors, architects, engineers, etc.
Should I supply references, letters of recommendation or proof of good conduct?
References and letters of recommendation are commonly used for high-level jobs. When listing referees, the applicant should inform the relevant person in advance and ask for their permission to include their name, phone number and job title in the CV.
Regulated professions usually need proof of good conduct as evidence of a clean criminal record.
