Final answer:
The 'fit and proper' criteria typically encompass legal requirements like age and residency, ethical considerations including good moral character, and professional or personal competence such as possessing expertise or readiness for a job.
Step-by-step explanation:
The three fundamental criteria for determining whether an individual is "fit and proper" for approval/registration in various contexts such as voting, holding public office, and other professional certifications are often based on a combination of legal, ethical, and professional standards.
Legal Requirements: This includes the adherence to specific age, residency, and citizenship conditions such as being at least 18 years of age, being a lawful resident, or having resided in the country for a determined amount of time. For instance, voter registration requirements may demand an eligible voter to meet certain conditions that prove they are entitled to vote in that jurisdiction.
Character and Ethics: The assessment of good moral character is crucial. This might involve scrutinizing past behaviors, criminal records, financial history, and public standing to ensure the individual upholds the ethical standards expected of the position or registration they are seeking.
Professional and Personal Competence: A demonstration of the necessary skills and knowledge is required. For professional certifications, this might include proving expertise in a relevant field. For holding public office, factors such as work history, health, and readiness to perform the job's duties are considered.
