It is a good idea to research paralegal schools and courses so to make sure the accreditation is accepted by the governing bodies. A good way to ensure this is to check that the learning credits are transferable to other schools and universities.
Accredited colleges and universities will have websites that detail their credentials, as well as links documenting their history, testimonials from ex-students and information from members of staff. Many tutors may also be licensed attorneys, so you will be sure that you are going to receive instruction from fully qualified members of the legal field.
Sham schools exist and it is for this reason that we state you should thoroughly research your chosen venue for learning. However, these sham schools tend to be easy to spot, and don't typically survive a long time. Research carefully, study hard, and you will be ready for an interesting and exciting career as a paralegal.
