An individual may first need to attend a community or technical college to gain the necessary grammar, computer and office skills required to become a personal assistant. Assistants in the medical or legal fields might need to earn a bachelor's degree or take classes on industry-specific terminology.
A personal assistant can complete her training on the job within a few weeks. Training for an assistant position in the medical or legal field can take several months to complete, as these industries require knowledge of the practices and terms that are specific to these fields.
Since a personal assistant often has more complex duties than a secretary or administrative assistant, she may need to learn how to do research, look over documents, manage clerical staff and draw up reports to succeed at her job.
A personal assistant can also earn certifications for job-related skills, but this is not a requirement. The International Association of Administrative Professionals issues the Certified Administrative Professional credential to individuals who have anywhere from two to four years of professional experience and successfully pass an exam.
Certification designation options for legal secretaries include the Accredited Legal Professional from NALS and the Certified Legal Secretary Specialist from Legal Secretaries International.
